CHAPTER XIX

TREATMENT BY RE-EDUCATION

The author of the article "Tic" in the Dictionary in Sixty Volumes of 1822 urges the necessity of care and perseverance in the correction of the involuntary movements characteristic of the disease. In 1830 Jolly recommended different exercises in the treatment of convulsions, as a means of interrupting the sequence of certain spasmodic phenomena. Blache's[220] adoption, in 1851, of medical gymnastics in cases of "abnormal chorea" was attended with excellent results; and Trousseau, as we have seen, extolled the value of exercises systematically applied to the muscles involved in non-dolorous tic. The principle of the treatment consisted in the regular execution of given movements by the muscular groups affected, to the rhythmical accompaniment of a metronome or the pendulum of a clock.

In these instances we have a forecast of the modern methods of re-education, so successfully employed to combat tic.

Letulle advises an appeal to the intelligence, good sense, and will of the patient in the endeavour to provoke an inverse effort at the moment when the tic begins, or even before. It is the prerogative of the physician to indicate suitable exercises and to encourage and aid the patient in his attempts. Even the most inveterate of tics may thus be controlled and made to disappear. On the other hand, the _Traité de médecine_ ignores the subject, while Lannois' paper in the _Traité de thérapeutique_ contains the statement that in the treatment of myoclonus--under which term various indefinite convulsive movements are comprehended--no method has hitherto been of any avail. Yet in another section of the same book we discover some sound advice anent tics and choreas of hysterical origin, emanating from the pen of Pierre Janet.

It is well to study the influence of the attention on these conditions; some tics are contingent on the direction of the patient's attention to them, others appear solely during times of distraction.... Education of movements by some form of drill may be of the greatest utility.

These general therapeutic indications are applicable to all kinds of tic, independently of their form and localisation. Moreover, they conform to the procedures advocated by Brissaud since 1893.

So long as tic is regarded as a purely external phenomenon, treatment is bound to be insufficient; but recognition of the relations between the convulsion and the mental state of the subject has made possible a rational therapeusis. There can be no doubt, thanks to the laborious work of Bourneville, that systematised mental discipline has sometimes a surprising effect on congenital psychical imperfections; and where the patients have attained a higher level of mental development, re-education has shown itself to be the method _par excellence_.

The credit of initiating treatment by forced immobility is due to Brissaud, who in the year 1893 first utilised the method in cases of mental torticollis. In the face of the risks of surgical intervention and the unsatisfactory nature of existing therapeutic measures, Brissaud emphasised the value of motor discipline in tic,[221] and it was not long ere rules were formulated and precision introduced into the application of the method.[222] The results were certainly encouraging, so much so that improvement could be promised if treatment was sufficiently protracted; cure, indeed, followed in various instances.

Brissaud's method is a combination of immobilisation of movements with movements of immobilisation. Speaking generally, the patient is directed to perform certain appropriate exercises under given conditions. Some of these exercises are intended to teach him how to preserve immobility, while the object of others is to replace an incorrect movement by a normal one. In the case of the former, immobility is alike the goal in view and the means of attaining it, while by recourse to suitable movements, in the latter instance, the same end is sought.

It is essential to remember that the exercises must be graduated. To begin with, the subject of tic is required to remain absolutely motionless, as for a photograph, for one, two, three seconds--in fact, as long as he can without fatigue. Very gradually the period is increased, for patients have their good and their bad days, and too great a demand on one day is apt to be succeeded by a relapse on the next. One must rest content with even the most insignificant gain at first, and soon the seconds will grow into minutes, and the minutes into hours. It is desirable to specify on each occasion the duration of the expected immobility. Place the patient at the outset in the position in which his tic manifests itself least often, and do not cease to encourage him by affirming that he can and must remain immobile. Once the séance of immobilisation can be maintained for as much as five or six minutes, begin to modify the patient's attitudes. If he has been comfortably seated during the opening performances, try him when he is standing, and as soon as he has accomplished this, vary the position of his head, arms, trunk, and legs, repeating the séance in each case. Eventually he will learn to maintain immobility of certain parts of his body while he is walking, or while he is executing given movements with his arms or legs. In all these performances direction must be specially directed to the patient's tic. The method is obviously simple, so much so that he may be inclined to question its utility and may fail to grasp its import. One must not hesitate, however, to explain its purpose; indeed, the rapid and intelligent appreciation of the method on the part of the patient is a _sine qua non_ for success. Patient and doctor most co-operate in defence and attack; and their union will culminate in triumph. Simultaneously with this discipline of immobilisation the subject must be taught the discipline of movements. The idea is to make him perform slow, regular, and accurate movements to order, addressing oneself to the muscles of the area in which the tic is localised. They must be very simple at first, and the exercises must be very short. The séance should never be prolonged beyond a few minutes, making, with the immobilisation, not more than half an hour. This time will, of course, soon be increased, but it is of prime importance to avoid fatigue. The performances should be gone through three, four, or five times a day, and always at the same hours. One of them at least ought to be under the personal direction of the physician, whose duty it is to modify, instruct, exhort, reprimand, as the case may be. In his absence the supervision of the exercises must be left to some responsible individual, who has an eye for faults as well as for progress. Statements by the patients themselves are to be considered with reserve.

The repetition of the prescribed exercises should take place in front of a looking-glass, whereby the patient may be exactly informed of any mistakes in gesture or attitude. He cannot otherwise judge of the degree of immobility attained, and may deceive himself, although he has the best intentions in the world, as to the real state of affairs. He does not know whether he is holding himself straight or not, as a general rule, but a glance in the mirror will correct his fault. A careful register must be kept of the progress he makes. Little by little the jurisdiction of the physician will be reduced, provided the patient maintains his interest in his own treatment. Indifference and discouragement are fatal, and it must be the physician's aim to prevent their occurrence.

Séglas has reported the history of a woman with mental torticollis, who submitted to treatment by Brissaud's method, and a remarkably quick alleviation was the result. At the end of three weeks, however, she allowed her interest to slacken, and ere long the benefits obtained were entirely frustrated.

It cannot be too often repeated that even though the tic disappear, the patient must not be abandoned to himself, but must be persuaded to continue his exercises. This is the price of success. As time goes on, it is true, he encounters fewer difficulties in his way, and once he is conversant with the method, he may be able to work out his own salvation.

In the case of children, the efforts of the medical man may often be seconded by parent or teacher, who has assisted at the first lessons and is in a position to superintend their repetition. On the other hand, treatment may be nullified by deplorable weakness on the part of father or mother. One of the reasons for the existence or at least the persistence of tics in children is that there has been no attempt at their correction when they were still "bad habits." Neglect or indulgence is an etiological factor of the first importance, as we have already seen. Many a time we have had occasion to note this, notwithstanding the protestations of the family. Fear of aggravating the mischief is sometimes advanced as a reason for non-interference. Nothing could be more misleading.

The method which seeks to check the youthful _tiqueur_ by the multiplication of threats and penalties is not to be countenanced; it produces the opposite effect to what is intended. Clearly the educational therapeutic measures we have been advocating demand a patience and an ingenuity on the part of both doctor and patient which we have no desire to minimise, but it is along these lines that success is to be reached.

A noteworthy adjunct to treatment is to sketch out a daily routine for the patient to follow regularly and punctually. His mental disarray is patent not merely from his disorders of motility, but in the unmethodical and changeable habits of his everyday life. To introduce discipline into his manner of living is a most wholesome step. To find something with which to employ his leisure time, to direct his energies into suitable channels, will prove to be eminently beneficial, not merely for the child but also for the adult. Those who tic ought to be able to contract good habits as readily as bad, provided their instructor be sufficiently persevering and inventive.

There is an infinity of occupations for the patient to put his hands to, and this variety suits his unsettled mood and his wavering attention; but longer efforts will be secured from him if his interest in his task can be engaged and stimulated as well. It is a good plan to make him write down each day what he does and how it is done, and to have him rehearse from time to time. Such pedagogical details are far from being superfluous; adults, moreover, are quick to gather their significance and to demonstrate their advantages in practice. That their fickle will must be reinforced they know well; how to achieve this end they are unaware. This fact explains their eager acceptance of the support furnished by these "moral crutches."

Generally speaking, there is no call to interrupt treatment once it is commenced, although occasionally we have found this desirable. The fatigue of the first few days, almost unavoidable as it is, and accompanied by new sensations, need occasion no alarm. We should acquaint our patient of its explanation, and so obviate the mental depression which its existence is apt to engender. Its ephemeral nature will soon become plain, for a rest of a few days suffices for its disappearance.

In some instances resort to procedures reminiscent of antagonistic gestures seems to have been of avail.

One of our patients,[223] suffering from facial tic, was directed to perform, as far as practicable, the opposite movements to her grimaces. If her mouth was drawn to the right, she forthwith made a corresponding twitch to the left; if her mouth was shut spasmodically, she was instructed to open it widely and quickly. By such simple methods, applied to all her tics, speedy control was regained, and once she had mastered the theory of the process, the practice of regular exercises and the development of antagonistic movements soon effected a complete cure.

Training of the antagonists has also been recommended by Hartenberg,[224] in a case of scratching tic. The patient was urged to approximate the hand to the affected cheek very slowly, and almost at the moment of contact the order was given to extend the arm briskly; this gesture of opposition, moreover, was stimulated by faradisation to the extensors of the forearm. The method, of course, is practically identical with that adopted by Frenkel,[225] of Heiden, who provoked energetic contractions of antagonistic groups by teaching the patients to overcome increasing resistances. Prudence, however, must be observed in carrying out these ideas, otherwise we run the risk of replacing one tic by another.

* * * * *

After the above general sketch of the essentials of the method, we may give examples of its application to particular instances.

For a tic of the eyelids, in especial for blinking tics, we make the patient open and shut the eyes to order, keep them closed or apart for a space, shut one eye and then the other, and repeat the same sequence in different positions of the head. It is a good plan to enjoin simultaneous action of the oral musculature. The cessation of tonic contractions of the eyelids with opening of the mouth has been remarked several times, and Oppenheim finds an analogy in the observations of Gunn and Helfreich, who have seen ptosis disappear as the mouth is opened.

If the eyeballs are involved in a tic, insist on dissociating the movements of head and eyes; make the patient follow an object slowly with his eyes while the head is stationary; or let the head deviate to right or left, up or down, while the eyes remain fixed on some particular point.

When the lips are the seat of involuntary muscular action, have the patient show his teeth, open and shut his mouth, purse his lips; make him speak and conform his expression to his speech; let him read aloud slowly, and fix his attention on his subject.

As a specimen of treatment for a facial tic, we may cite the subjoined programme:

Every day, and three times a day, at the same hours--nine, one, and six--the patient is to look at himself for two minutes in a mirror, preserving absolute immobility the while; to read aloud for two minutes, to speak in front of the glass for two minutes, to walk backwards and forwards in front of the mirror for two minutes. During the ten minutes of these exercises he will endeavour to keep his facial musculature under control. If the tic assert itself in the course of one of the exercises, he will recommence the latter, if necessary twice; the third time he will leave it till the next séance.

For tics of the head and neck, such as tossing tics and mental torticollis, inclination and rotation movements are indicated, of which an instance may be quoted:

Mademoiselle R. is quick in learning how to correct her muscular faults. Her actions are gradually becoming more complete and ample, and if she performs her allotted task with little animation, at the least there is no question of her indefatigable willingness. In less than a month she has been able to fix her regard, open her eyes widely, turn her head, uninterrupted either by halts or twitches; she can remain motionless in front of a looking-glass for as long as a minute. Equally satisfactory progress hat been made in the art of reading aloud; she breathes more regularly, and articulates more distinctly.

Thus the patient has come to realise that she need but give her attention to the involuntary movements for them to cease, and there has been a synchronous advance in her mental activity and power of concentration. Her nonchalance and timidity have diminished; she is no longer indifferent to her surroundings, nor furtive in her glances; she enters into conversation with zest, and her movements are characterised by decision.

Take another example of treatment, for a case of mental torticollis:

Stand or sit in front of a mirror and endeavour to maintain an absolutely correct position of trunk and shoulders.

Lift the arms vertically and turn the head to the right, then lower the arms while the head remains as it is.

Bend the body forward, and stretch the arms out till they touch the ground, the head meantime being rotated to the right. Then rise up again with the head in the same attitude. After two or three efforts it will be found that the head can be kept straight for a few seconds.

In tics of the limbs, shoulders, hands, feet, innumerable movements will suggest themselves for practice. The young girl with a tic of genuflexion, under the care of Oddo, supplies an excellent proof of the value of Brissaud's method:

The immobilisation of movements was realised by the mother forcing the child to remain motionless in a fixed position for augmented periods. As for movements of immobilisation, the patient made peregrinations of increasing length under the mother's eye, the order being repeatedly given to suppress the genuflexions. At the same time, massage and passive movements to the limbs and joints were prescribed, with a view to diminishing the articular cracks--the exciting cause of the bizarre tic from which the girl suffered.

In the course of ten or twelve days the genuflexions had entirely vanished, and a return of the pain in the coxo-femoral articulation aided materially in consolidating the effects of the treatment.

Tics of speech should be handled in the same way as stammering. "We do not treat stammerers, we educate them," says Moutard-Martin. There can be no gainsaying the convincing results obtained by Chervin's technique.

For years there has been unanimity of opinion on the value of respiratory gymnastics in the treatment of stammering. The plan is to make the patient inspire deeply and quickly, and follow this with a prolonged expiration. Difficulties of articulation and phonation may be overcome by recitation, by declaiming, by scanning utterance, by dwelling on the vowels, etc. Various authors have laid stress on the advisability of concomitant therapeutic treatment.

In cases of stammering (says Olivier), all surgical interference is to be deprecated. Operations on the nose or throat are directed toward the removal of obstructions in the air-ways, but they are merely a preparatory step to the adoption of the education method. No one of the vaunted "cures" for stammering is infallible, since all depend in the last resort on the will power of the patient, nor is there anything mysterious about them. Isolation is not always indicated; what is indispensable is reinforcement of the will.

The intimate relation between tics of speech and various kinds of stammering has led to the application to both of the same re-education methods. Pitres,[226] in particular, bases his line of treatment for tics in general on regulation of respiratory activity, as he has observed that tics diminish or die away with a deep and regular respiratory rhythm. His plan is as follows:

Supported against a wall, with shoulders braced back, the patient is instructed to take slow and deep inspirations, raising his arms the while, and letting them fall with expiration. This performance is repeated three times a day, for ten minutes at a time.

The method has been elaborated by Tissié, and Cruchet also has thereby obtained excellent results, which he has put on record in his thesis.

The patient is placed upright against some support, his heels together and his arms by his side. For the first three minutes he recites aloud, drawing a slow deep breath at frequent and regular intervals. Then he proceeds to make similar long inspirations and expirations, elevating his arms synchronously with the former, and depressing them with the latter. The exercises may advantageously be repeated every three hours to begin with, then their duration may be increased and the intervals lengthened, until the séances are extended to fifteen minutes three times a day. Their continuance will vary with the individual, but the ultimate aim is to reduce the period and to spin out the interval still more, until eventually their object has been attained and they may cease.

A concrete example may be given:

A young man had suffered for eleven years from generalised tics of peculiar intensity. Every few seconds violent twitches of an electric-like rapidity seized the muscles of his head, trunk, and limbs, to the accompaniment of abrupt cries and inarticulate growls. A sojourn of a few weeks in hospital, and the acquisition of the most elementary technique in athmotherapy, resulted in a complete cure ere many months had passed.

Tissié explains the action of this method on tics by a special action of regular respiration on psychomotor centres. Raymond and Janet incline to the opinion that attention depends on respiratory activity, but Tissié[227] argues there is antagonism between deep respiration and maintenance of attention, and Cruchet supports this hypothesis.

If we prescribe respiratory exercises, we are temporarily suppressing the attention, and reducing psychical activity to a minimum. Thus tic, which is a reflex of thought, does not occur, and if the exercises are renewed often enough, the habit will gradually be lost.

In our opinion, it is precisely the bestowal of the attention on the allotted task that has such a salutary effect. Whatever be the movements, they demand of the patient a momentary halt, a momentary interruption of those ill-timed motor reactions that make concerted action impossible. Observation shows that the degree of successful control is in proportion to the degree of concentration of the attention. The novelty of the exercise in itself acts as a stimulus, but when this novelty wears off, faults are prone to reappear. Hence the necessity of varying the procedures, and of rendering them always interesting; in the end the habit of supervision is contracted, and the patient feels increasing satisfaction in watching his physical infirmities daily diminish and the resources of his will daily widen.

Respiratory drill is an admirable method of procuring this result; it acts in the same way as any of the other exercises. Its use is not confined to tics of speech or of respiration, for thoracic muscles are involved in tic much more frequently than is commonly supposed. By resort to this technique Madet cured an expiratory hiccough[228] in a man of forty-six, who was afflicted in addition with twitches of head, trunk, and hands.

Systematized exercises have of course the advantages of exercise in general; motor, sensory, and psychical functions alike are stimulated and regulated, and tend to become normal. In particular, muscular exercise is a striking way of disciplining volition. Accordingly, we never fail to prescribe such pastimes as gymnastics, in any of its forms, rowing, fencing, cycling, lawn tennis, etc.; games which demand attention, skill, and decision are useful auxiliaries, and manual occupations of a more delicate nature ought not to be forgotten, provided they require of the patient a certain amount of immobility. Every case, needless to say, must be treated on its merits, but the general indications we have supplied can easily be modified to suit the individual.

The various procedures directed, under different names, to the suppression of tic by re-education, are all modelled on the same plan. Köster attributes the disease to exhaustion of higher co-ordinating centres, and counsels their reinforcement by appropriate exercise. Oppenheim, in his _Lehrbuch der Nervenkrankheiten_, adduces evidence of the value of what he calls _Hemmungstherapie_, which is merely an application of the principles and therapeutic rules laid down by Brissaud in 1893, and described by one of us in 1897, apropos of mental torticollis. The same may be said of the line of treatment pursued by Dubois, which appears to be based on the pathogenic interpretation given by Oettinger,[229] according to whom the brain of tic patients is incapable of conserving the image of sustained immobility, and thereby loses the habit of voluntary immobilisation. The essence of treatment, therefore, consists in habituating the subject to rest motionless like a statue in a position conducive to repose, and for a given time.

As has been already remarked, the polymorphism of tics is such that the plan of treatment selected must be necessarily elastic if it is to be altered to suit individual cases. What is the point in enjoining absolute immobility on a patient whose blepharotic is never in evidence unless he is walking about?

* * * * *

We may now proceed to narrate the details of various cases of tic treated by the combined method of disciplinary movements and immobility, taking the history of O. as our first example.

_October 15, 1901._--Séance of absolute immobility in the upright position, with the head straight, for five seconds; to be repeated in front of a mirror for five minutes, with intervals for rest of fifteen seconds. Movements of rotation of the head to left and right, with progressively lengthening pauses in each of the extreme positions. Respiratory exercises with elevation and depression of the arms eight times a minute, decreasing steadily to four a minute. These exercises are to occupy a quarter of an hour morning and evening. Explain to the patient the action of the sternomastoids and how they combine to fix the head. Make the patient lie on his back and move his head antero-posteriorly.

_October 19._--O. has still his tics, but he can already remain motionless on command, and is conscious of satisfaction in so doing. Just as his exercises come to an end there is always a momentary recrudescence of the tics, but a very appreciable calm follows.

_October 21._--Immobility is maintained well for half a minute. The patient is to resume his cycling and fencing, physical exercises which he has abandoned for more than a year.

_October 25._--O. considers himself greatly improved. He has gained insight into the way of combating his tics, and his self-confidence is on the up grade. For several days he has devoted his attention to his tic of blinking, with the result that he can open his eyes longer and more easily.

_October 28._--He evinces a preference for certain of the exercises: if they please him, he performs them accurately; if they do not, they are neglected.

_November 20._--The head tics are still rather violent at times. A period of intellectual and bodily fatigue has supervened, but he tries his fencing again, and to his profound satisfaction he has managed to keep free of tics during the bouts. He is recommended to avoid all possible causes of cerebral and physical exhaustion.

_December 3._--He continues to make satisfactory progress. His habit of supporting his chin on his cane is abandoned, though an attempt to dispense with the latter entirely, when he is out in the street, has ended disastrously. He is content to hold it in his hand and strike his leg with it from time to time.

_December 13._--Whenever O. is tempted to tic again, he stands in front of a mirror and commences to sing, and while the song lasts his tics remain in abeyance. His trick of sitting crossways on a chair and rubbing his chin against the back is also discarded, with the result that the callosities have vanished. As far as his walking is concerned, he has adopted the plan of endeavouring to get from one point to another without allowing his tics to assert themselves, and his efforts have been crowned with success.

_February 3._--The patient has recovered his self-confidence, and the compliments of his friends prove an additional restorative. It is true the tics still recur, but their number is less, their duration shorter, their severity considerably diminished. What O. is best able to appreciate is the disappearance of the state of _mal obsédant_ that accompanied them.

Take another example in the person of young J.:

In his case our object was to discipline him by successive modifications of his caprices. The first important result achieved was the suppression of his precious mattress--a result not obtained without difficulty, for the mere mention of it sufficed to provoke floods of tears and ebullitions of anger. He was then sent into the country for a few days to forget his heart's desire, but the labour was lost. No sooner had he arrived than he discovered another mattress in a barn, and transferred his affections to it.

Eventually the day came when he was finally convinced of the absurdity and inconvenience of his practice, and when the tender yet firm remonstrances of his parents prevailed. The prospect of congratulations awaiting him, and his own keenness to get better, stimulated him to fresh efforts, and the reward was success.

Not long after, however, he began to complain of mental suffering from the restraint laid on him, and the distress was undoubtedly genuine. We accordingly gave him permission to stretch himself on his bed at certain fixed times and for a fixed period, which was to be reduced each day by some minutes. He entered into the spirit of the regulations so happily that in less than a month the period spent in the horizontal position had sunk from two hours and three quarters to an hour and a half daily, and at last it was dispensed with altogether.

On his "nervous movements" re-education by immobility and methodical exercises had a beneficial influence, and he acquired the faculty of controlling his variable and attitude tics. Repetition of the séances under the eye of the physician, drill in front of a looking-glass, symmetrical and synchronous exercises for the arms, as well as ordinary practice in dressing and undressing, buttoning and unbuttoning clothes, eating, drinking, etc, with the left hand--all contributed materially to his progress. Many other re-educative prescriptions were enjoined on the patient; suffice it to say that in three months he was able to dress and feed himself, to behave properly at table, and to restrain himself generally, in spite of the obstacles provided by his babyish tricks and natural weakness.

Further, the advance he has made has reacted profitably on his mental condition, and if his fickleness and vacillation persist, at the least the trend of the educative exercises has been in the direction of reinforcement of the will. Hence is it that he is now more attentive, less introspective, less capricious; he is no longer overwhelmed at the gravity of his condition; he is conscious of having taken its measure, and of his power to master it.

We have also applied Brissaud's method to the treatment of variable chorea, with no less encouraging results. Its worth in cases of mental torticollis has been noted by several authors as well as by ourselves. A cure resulted in a peculiarly difficult instance recorded by Martin[230]:

A young man of twenty-six suffered from melancholia and hypochondriasis. He used to complain that his limbs were hopelessly rotten, that his hands, feet, legs, were gone, vanished; his head and neck had ceased to exist. So easily was he irritated that to most questions he vouchsafed no answer. His sentiments of affection were much blunted; a visit from his mother evoked no pleasurable sensation. All day long he used to lounge on a couch, his head sunk on his breast, and inclined somewhat to the right. The attitude was exaggerated if he was addressed, but while he could raise his head, by the help of his hand, to regard his interlocutor, it resumed its position of flexion as soon as he withdrew the support. Confined to the left side of his face was a tic which consisted in abrupt and jerky elevation of the corner of the mouth. On request, he would gain his feet laboriously and walk with abdomen protuberant, back arched, and legs apart. From time to time the neck musculature on the left side was the seat of convulsive movements. The left sternomastoid and trapezius were in a state of tonic contraction, and on any attempt being made to correct this vicious attitude, spasm occurred, and the patient resisted to his utmost.

On March 10, 1900, treatment was begun; an effort was made to gain the patient's confidence by explaining that a cure was within the bounds of possibility, and by demonstrating to him that his limbs, which were in a state of slight contracture, could be moved by his hand. The procedure was renewed three times a day, and followed by baths and massage.

By April 15 the contractures had disappeared, and he could perform any movement of relaxation himself. His attention was now drawn more particularly to his head, which was still in a faulty position, and annoyed him considerably. Advantage was taken of an improvement in his tractability to make him perform some movements of his neck. At first the mere effort produced a spasmodic contraction, but he was able to move his head very slightly up and down. After five months of such treatment, occupying on an average three hours a day, his mental torticollis was finally reduced to subjection, an interesting feature of the case being the parallelism between the physical and the psychical improvement.

On three occasions since we have noted a recurrence of the torticollis, but each time it has been both brief and easily overcome. The cure has been maintained now for upwards of a year, and four months ago the patient resumed his work.

We must impress ourselves with the importance of recognising the proneness of tics to relapse. Any triviality which may have a prejudicial effect on the patient's will-power is calculated to facilitate the reawakening of a bad habit. Such relapses are commonly transient, and are instructive in so far as their manifestation sometimes differs from the original tic and entails alterations in treatment.

L., for instance, whose condition was one of permanent rotation of the head to the right, had a fit of depression after eight days of treatment and noteworthy improvement, a depression so severe that she questioned the practicability of a cure, and forthwith her head began to turn to the right again. On this occasion, however, the tic was an intermittent one, consisting of clonic contractions of the cervical muscles chiefly, without antagonistic gesture. For five days the fit persisted, and was sufficiently acute to render omission of the exercises advisable.

After some days' rest a beginning was made with the treatment again, under the direction of one of us and in the presence of her father. We took care to place ourselves always in front and to the left of the patient, on the side opposed to her torticollis. The position allotted her at table was such that in order to converse with her parents she had to turn to the left.

Not long thereafter a second fit of depression occurred, but on this occasion her head began to rotate to the left. She had been under treatment for six weeks, when she made the remark one day that her head seemed once more to be drawn to the right. She hastened to add, moreover, that she had discovered a means of remedying the mischief--viz. by putting her left hand to her left cheek--a corrective proceeding nothing short of paradoxical.

It was about this time that the pains and dragging sensations in the muscles of the neck subsided. On the other hand, for days on end, then for gradually diminishing periods, there existed a slight trembling of the head, due to muscular exertion, and explicable by the contraction of small cervical muscles on one side and their antagonists on the other.

On more than one occasion we have remarked this trembling as the forerunner of a cure. It vanishes spontaneously as the amelioration of the patient's condition becomes more definite.

Several months may intervene between relapses. Descroizilles cites a case of convulsive movements of the head and shoulder of three years' duration, which yielded to exercises in a few weeks. The tic reappeared six months later, and, resisting treatment by gymnastic discipline, was cured by suspension. Three months later it returned once more.

Facts of this description emphasise the desirability of considering rapid cures with reserve; where the improvement, on the contrary, is insensible, the results are much more likely to be permanent. Unforeseen complications, again, may arise once a cure is affected.

One of our patients[231] had been rather quickly relieved of a mental torticollis by the usual therapeutic measures, and we had allowed him to resume his avocation, when he suddenly appeared in a depressed and despairing mood a month later to say that he was worse than ever. The rotatory tic had not returned, it is true, but its place was taken by another phenomenon. If, as he walked along with head straight, his attention was suddenly directed to the right, he seemed at once to become "crystallised"; he halted, and could not deviate his head as he wanted, and at the same moment something appeared to choke him; in three or four seconds all was over, and his action unimpeded. As a result of these attacks he sank into a wretched state of more or less permanent anguish. A visit to his country home was of little avail; no sooner had he arrived than his head began to twist about in every direction, although, try as he would, he could not move it backwards. We accordingly prescribed absolute rest in bed, a strict regime, hydrotherapy, and unfailing regularity in the performance of gymnastic exercises. Not long after a fresh torticollis developed, by which the chin was deviated to the left and the head tilted to the right. Once more we initiated a scheme of regular drill, and in the course of a short time a satisfactory cure ensued. During the last three years we have had frequent opportunities of seeing our patient, and can certify that he remains mentally and physically normal.

Facts such as these teach us two things: the task of the physician is not ended with the disappearance of the tic, for it is the pathological mental state of the patient which renders him so easy a prey, and if we can modify that state by re-education, we may count on the cure being permanent. For a long time, however, we shall be well advised to talk simply of improvement. In the second place, relapse or slowness of progress is no reason for despair; treatment may have to be persevered with for a year or years, till the patient learns how his muscles act, how to maintain immobility, and how to effect a voluntary movement--notions which his fickle mind has hitherto neglected to grasp. Education of the will in the direction of control is calculated to bring him into line with normal individuals.

A radical cure is not without the bounds of possibility, but it depends greatly on the patient himself; his success is contingent on his faithful repetition of exercises long after the tic is gone; for while a cure results whenever the tic ceases to incommode its subject, fatigue or emotion on some future occasion may reawaken the tendency to involuntary movements, and only a methodically trained will can triumph over the temptation to relapse.

With this reservation, one may expect permanence in the cure, provided the affection is of recent date and the patient gives evidence of his assiduity and desire for relief.

MIRROR DRILL

Among various re-educational procedures which are worth mentioning for their practical value, a place must be given to what has been called mirror drill by one of us.

We all know that the term mirror writing is in use to specify that mode of caligraphy which looks exactly like ordinary writing when it is reflected in a mirror or if the paper is held to the light and seen from the reverse side. Mirror handwriting may be done with either hand. If the right hand be employed, the characters are traced from right to left and are centripetal in relation to the axis of the body. If, on the contrary, it is the left hand that we use, the letters go from right to left, but they are centrifugal.

Innumerable examples of this condition have been described and various theories elaborated. Apart from such cases, it is a matter of common observation that if any one be asked to write synchronously with the two hands, his left hand will tend spontaneously to adopt the mirror form.[232] The experiment may be tried on some one who has never made the attempt to write with the left hand, and has never heard of mirror writing. Ask him to abandon his left hand completely to the movements it may be constrained to fashion while the right hand is tracing the required words, and let his eyes be closed; in practically every case the left will make mirror characters. It may therefore be contended that mirror writing is the natural writing of the left hand, an opinion supported by Vogt, Durand, etc., and more recently by Ballet,[233] who remarks that this variety of writing for the left hand is natural in left-handed people who have not been influenced by education.

The actual form of the characters is of little significance. We have often repeated the experiment and substituted Greek, German, typographic and stenographic letters, but always with the same result. It is perhaps worthy of note that in simultaneous writing considerable modification of the letters traced by the right hand occurs; they become hesitating and childish; the lines are sinuous and irregular, and the characters themselves ill distinguished. The same holds good for drawings.

On the other hand, the first attempt of the left to make mirror writing to order is frequently laborious. Mingled with true mirror characters will be found ordinary letters automatically traced, for automatism of left-hand movements is not the inevitable sequel of automatism of right-hand movements. From time to time the visual image of a normal letter rises in the mind, an image which does not correspond to that which the hand is endeavouring to express, whence doubt, reflection, arrest, and, usually, error. If, however, the subject allows his left hand to write, without preoccupying himself with the shape of the letters it is making, or with his eyes shut, automatism reasserts its sway and mirror writing results.

Of course a person who is asked for the first time to use his left hand in writing may force himself to trace ordinary characters, but to do so he must evoke the visual image of each letter and seek to reproduce the contours of this image slowly, yet often inaccurately. There is nothing automatic in this. Hence it is that ordinary writing with the left hand demands prolonged education and patient effort, and may never attain any rapidity, whereas mirror writing with the same hand is acquired with facility in a more or less automatic manner.

It may well be that the natural left-hand mirror writing of which we are speaking is a purely motor phenomenon, since the calling up of the visual images of letters, so far from proving of assistance, is calculated rather to obscure and hamper it.

It has been pointed out by Ballet that variations in the aptitude for left-hand mirror writing exist, especially in the case of those who cannot write without the aid of the visual image of letters. Since they copy this image in using the right hand for caligraphical purposes, they are tempted to do the same when the left is in use. In fact, the facility with which one learns mirror writing seems to depend on one's power of writing without recourse to these images. The explanation of the ease with which the left hand reproduces, in the guise of mirror writing, the movements of the other, is to be sought in the symmetrical arrangement of the muscles in relation round the body axis. Physiologists tell us, further, that the simultaneous contraction of two symmetrical muscles is more readily attained than that of two asymmetrical muscles. The law of symmetry and the law of least effort correspond.

What is true of writing is no less true of all other forms of motor activity. In physical exercises the surest results are achieved by the synchronous contractions of symmetrical muscles, whereas education is much more arduous should this lesson from experience be ignored. For instance, nothing is easier than to make the arms describe circles in the same direction, but rotation in opposite directions is very difficult. Few people can revolve their thumbs in opposite ways. This is a matter of common observation among teachers of physical culture. The rapidity with which the action of swimming can be learned is in striking contrast to the slowness with which the art of fencing is apprehended. Little effort is required of the music beginner if his pianoforte exercises demand the activity of symmetrical muscles for their execution; on the other hand, the playing of a scale by the two hands in unison comes only with long practice, since it entails the simultaneous use of asymmetrical muscles.

Facts such as these are of more than passing interest. One cannot afford to neglect their import where muscular education is concerned, whatever be its nature, whatever be its object. Yet there is an unfortunate tendency to concentrate attention on the development of the skill of one arm only, and that the right. Sometimes the use of the left arm for certain purposes is criticised adversely, and of course most people are congenitally less able to work with it. But habit, example, and even fashion, combine to render the right arm preponderant in everything, to the detriment of the other. It is a common occurrence to attribute awkwardness to this left arm, when its inferiority is really nothing else than a sign of faulty education. In many cases the left is as good as the right; its apparent _gaucherie_ is because of its attempt at executing movements which are similar to those of the right, instead of those which are correspondingly opposite.

Thus experience shows that the education of the right upper limb is reflected on the left upper limb, although the subject may be sublimely ignorant of the fact. But though this influence be latent, it is none the less real, and may prove of service if occasion arise. Weber, Fechner, and Féré[234] have all devoted attention to this subject.

From the therapeutic point of view, considerable significance attaches to these facts. Temporary disablement of the right arm, such as follows fracture or arthritis or writers' cramp, need not be disconcerting, for the patient can proceed to utilise the faculty for mirror writing which his left hand has unconsciously acquired. In all affections which are accompanied by troubles of motility it is an excellent plan to apply the prescribed muscular exercises to both sides of the body, and the regularity with which they are performed on the sound side will have a corrective influence on the mirror movements of the affected side. We assume, of course, that there is no irremediable destructive lesion which interferes with the continuity of paths joining functional centres, otherwise the education of the normal limbs could not be expected to produce any beneficial effect on the other. It is especially in motor disorders of functional origin that mirror movements prove useful, and the frequent unilaterality of these disorders readily allows of the institution of a re-educative mirror drill. Speaking generally, the faculty of writing supplies us with the best means of attaining our end, for the variety of exercises it offers is likely to rivet the patient's attention, and he has proofs of his progress under his eyes. The goal in view is not, of course, the attainment of caligraphical perfection--the subjects of tic are seldom guilty of bad penmanship; but the execution of the required movements demands a voluntary constraint that cannot but be profitable.

After the séances of absolute immobility, then, our custom is to set daily exercises in writing, drawing, painting, tracing, ornamentation, etc., varying the indications in accordance with individual tastes and aptitudes. At the same time, we insist on the patient's devoting both hands simultaneously to his task. It will be found advantageous to devise movements for the fingers, then for the hand, the forearm, and so on, and to instruct him in each successively. Thus, one may begin by having him make the movements in space, then with chalk on a blackboard placed vertically, then on the same placed horizontally, or on the ground; or he can be asked to trace symmetrical designs and ornaments on a wall. The essential points are that he use both arms simultaneously, symmetrically, and accurately, and that all inopportune gestures be inhibited.

In several of our cases procedures such as these have been adopted. O. was not long in acquiring the faculty of writing with both hands, the left tracing mirror characters. The object of the exercise was to oblige him to maintain tranquillity and a correct position of his head and neck, while his hands were simultaneously employed. By this means, as well as by synchronous drawing exercises, he soon became so deft that he learned to conserve almost complete immobility during the performance, to his great satisfaction. No less creditable results were attained with L. and with young J.

The method appears to us to be indicated above all in cases where the left arm is the seat of tic. Any one who can use a pen with his right hand is not long in acquiring the faculty of mirror writing with his left. In this way the simultaneous execution of a normal movement with right hand and left is facilitated, and the sound limb imposes regularity on the other. Whatever be the localisation of the tic or tics, this is the technique to adopt. It presents this advantage, that its combinations and permutations serve to stimulate the patient's interest, and he, at the same time, is required to keep a watchful eye on his involuntary actions; so is his will disciplined.

REST IN BED

In the majority of cases absolute rest in bed is not desirable, but a youthful patient should always be sent to bed early, and be allowed to lie long; twelve hours in bed is not excessive. This rule is one which must not permit of exceptions; whatever be the excuses invented by the parents, we should see that it is rigorously obeyed. Two or three hours' rest some time in the course of the day may be enjoined, provided the period be fixed and uninterrupted. To break in on frequent siestas with little promenades or with times of unrest is not productive of any good.

If it is impossible to maintain discipline during the day, absolute rest in bed for a longer or a shorter period may be counselled; the sedative effect of this measure cannot be gainsaid, especially when, for no apparent reason, exacerbations develop, with increase of emotional, obsessional, or other psychical phenomena.

ISOLATION

Isolation is a rather severe proceeding, which, however, one must not hesitate to utilise in rebellious cases, or if the patient's mental state precludes the possibility of prolonged application of systematic discipline. Wyemann[235] cites a successful case, where a youth of seventeen, with a bad family history, suffered from convulsive movements in association with coprolalia, and was cured of the latter by isolation. Some would even recommend the removal of the patient to a hospital for mental disease. Such a step, however, is rather premature, for he may already have begun to improve where he happens to be, and it is not always certain that a sojourn of this character will be beneficial.

Before isolation is resorted to, it is important to familiarise oneself with the patient's mode of life, to ascertain whether it is capable of modification in accordance with one's ideas for treatment, and to determine the exact influence of his environment on him. We have frequently had occasion to remark how potent is this environment as an etiological factor; with young people, in particular, negligence on the part of parent or guardian places the child in jeopardy. To combat this unfortunate tendency must be our aim, as soon as we are convinced of the risk.

Sometimes it is sufficient to draw the attention of the parents to the disastrous consequences of indulgence or indifference; but we shall show our wisdom in not relying too much on promises, however sincere and solemn. These parents may be perfectly honest in their protestations, but they are often as changeable and weak as their offspring, and lack that very firmness and perseverance which they imagine themselves capable of exhibiting. Thus, in spite of their undoubted intelligence and good will, their efforts at control are unsatisfactory, and under such circumstances the withdrawal of the patient from his family circle is urgently indicated.

We cannot think, nevertheless, that the asylum is the ideal--there is risk in the contiguity of other neuropaths or psychopaths; and while the value of rigorous isolation consists in its stimulating and quickening effect on the patient's self-control, whereby the day of his return to ordinary life is hastened, yet it too frequently happens that the old temptations are as powerful as of yore, and that the same causes which operated when his tics first made their appearance reawaken vicious tendencies more or less imperfectly masked.

Most subjects learn to still their tic during the physician's brief visit; further, most achieve a similar result while they remain inmates of a special institution; but as soon as they find themselves in their old quarters, so soon does the impulse to tic dominate them again. In fact, their victory is incomplete; the ground they gain is not held. The goal to strive after is the repression of their tic under all conditions, apart from extraneous intervention and influence. Once he has been instructed in the methods of inhibition, the _tiqueur_ has no one but himself to fall back on when face to face with the allurements of his daily life.

These reserves made, it is clear that removal of the patient from his environment has its advantages, but it is better to maintain only a degree of isolation, and to allow him to come into his own circle from time to time, under a wise supervision. The ideal measure would be to consign him to the care of an attentive and devoted teacher, whose superintendence would be permanent. In this respect, unfortunately, all that we can do at present is to indicate what we think a desideratum, for while well-to-do families may have their tutor, we do not know of any one who has held a corresponding office as an instructor of children with tic. The realisation of this novel proceeding might present genuine difficulties in practice, but we may hope that once parents, patients, and physicians are acquainted with the nature of tics and the efficacy of the re-education method, many prejudices against that fruitful therapeutic contrivance will vanish.

PSYCHOTHERAPY

Immobilisation and regulation of exercise and occupation do not constitute the whole of the treatment; they form merely its objective side. Psychotherapy is another factor, of capital importance.

In the words of Brissaud, psychotherapy is an _ensemble_ of agencies calculated to demonstrate to the patient where his will is at fault, and how to exercise to the best advantage what of it is left. To come to particulars, his defect lies in his inability to check a cortical caprice. These are not rhetorical unrealities, nor is there anything mysterious about the method; it demands no special competence beyond the gentle and encouraging firmness of the ideal teacher. The physician can constitute himself instructor without having to borrow from the more or less occult practices of hypnotic suggestion. In fact, we must make it clear to the patient that the co-operation of the latter is indispensable, and that it is his will which is to come into action. The personal influence of the teacher will be exerted in sustaining his pupil's efforts, in making him take note of the progress effected, in keeping him to the allotted times for exercise and drill.

Thus, and thus only, is psychotherapy to be applied to tic. Lucid and sincere explanations and kindly counsels are wanted, not ceremonies and mysterious paraphernalia. Resoluteness, patience, clemency, and good sense are the weapons in the physician's armamentarium; docility, faith, and perseverance, on the patient's part, will enable him to emerge victorious. As soon as the compact is made, the battle against bad habits, where there is neither truce nor quarter, commences in earnest. The victim to tic will speedily unlearn the habit of perpetuating bad habits; he will, in addition, learn the habit of not contracting bad habits. In this way a double benefit--physical as well as moral--will accrue.

As a consequence, psychotherapeutical treatment directed specially to the subject's mental condition is scarcely necessary. The plans adopted to inhibit inopportune motor manifestations will prove of value for psychical imperfections.

Education might almost be considered a species of prophylactic treatment, intended to obviate the possible development of tics. Bourneville has verified this statement in his experience at Bicêtre:

Gymnastic exercises, and other measures directed towards the development of the child's faculties, ought to be conducted with kindness and gentleness, and by the aid of boundless devotion and patience the methods of the authorities are bearing unexpected fruit every day. We are convinced that the infrequency of tic in such as have reached puberty is attributable rather to the zealous application of a sound pedagogical method than to anything connected with the age and physical development of the child.

Results that steadfast and patient nurses and teachers are obtaining in an institution like Bicêtre may surely be obtained by the physician in his private practice, if the parents of a youthful candidate for tic would appreciate the importance of discipline and unite, intelligently and assiduously, in the task of education. How common it is to find them solicitous only of loading his tender brain with learning, instead of endeavouring, with all their mind and heart, to restrain deplorable bad habits that may one day blossom into tics, to the distress of all concerned! The physician's earliest duty is to warn the parents of the dangers of indifference, and thereafter to install himself as teacher, if the disease should manifest itself in spite of his precautions. He has no choice in the matter, and he should have the frankness to say so, indicating at the same time on what his convictions rest. He need have no fear of damaging his professional prestige by the simplicity of his methods. Let him not promise what he may not be able to perform; encouragement, not deception, must be his watchword. Along these lines lies his duty as a physician; there, too, will he find that his treatment will be fraught with success.

APPENDIX

_Les tics et leur traitement_, of which an English translation is here presented to the medical profession, was published at the close of the year 1902. In it our knowledge of the vexed subject of tics and spasms has been summarised and reviewed, and its reception in France, together with the fact of its having been translated into German without delay, prove that it has been regarded as the standard work on a topic the importance of which is being daily emphasised. At all the recent Congresses on the Continent the tics in one or other of their aspects have provided fruitful matter for discussion, whereas in England they have hitherto been greatly neglected. In the brief space of time that has elapsed since the book was produced there have been many and varying contributions to the subject, as a reference to the Bibliography herewith appended will show. Without doubt the reawakening of interest is in considerable measure due to the stimulus provided by the labours of MM. Meige and Feindel, yet it cannot be maintained that they have said the last word. In order that English readers may have before them the latest available information on the tics, various paragraphs from Meige's monograph (1905) have been incorporated, as has already been remarked in the Prefatory Note.

It is desirable, however, to indicate briefly certain points on which opinion is still divided, points on which the results of the most recent observations help to shed some light. Probably it has not escaped the reader's attention that the authors have with commendable wisdom refrained from dogmatising on some of these, although they are always able to give reasons for their adherence to one or other view. But in one respect at least the attitude which they have adopted has been unmistakable, and that is in regard to the fundamental importance of agreement in the matter of terminology.

The amount of misconception that exists about what constitutes a tic is almost beyond credence; indeed, only those who have had occasion to examine the literature can have any adequate idea of it. Discussions at neurological and other societies not infrequently reveal how vague are the notions of many who must have more than a passing acquaintance with the disease clinically. Now, a great deal of this misconception would disappear if the distinction between a tic and a spasm elaborated by Brissaud were adhered to, as the authors so strenuously advocate. It is quite unnecessary to insist further on this point, but, on the other hand, it is only fair to state that even in France the views of Brissaud, Meige, and Feindel do not command universal acceptance.

M. Cruchet, of Bordeaux, to whom frequent reference is made in this volume, has in several communications on tic expressed himself at some length, and some of these have made their appearance since the publication of _Les tics et leur traitement_. According to him, the original meaning of the word "tic" is a movement arising in a "bad habit," and there would never have been any confusion had the term "tic douloureux" not been introduced. We know well enough the exact significance of this term, but its use led to, the adoption of the cognate term "tic non-douloureux," and in the latter group two absolutely different conditions have been confused--viz. true tics, and spasms in Brissaud's sense. The difference between the two is now recognised everywhere in France; but in England and America, as Risien Russell points out in his article in Clifford Allbutt's _System of Medicine_, tic is still applied to such conditions as facial spasm and the involuntary movements of trigeminal neuralgia, whereas it should be reserved for what we usually call "habit spasm" and "habit chorea." The advantage of the word "tic" over these rather cumbrous terms must be patent to the unbiassed mind.

It is, however, in his persistent affirmation that a tic, to be a tic, must be clonic, that Cruchet disagrees with the tenets of Meige and Feindel. He has abandoned the use of the term "organic tic" in favour of spasm; and he maintains that "tonic tic" and "tic of attitude" should give place to "habit attitude" and "convulsive attitude," as the case may be. His definition of tic is in the following terms:

Tic consists in the execution--short, abrupt, sudden, irresistible, involuntary, inapposite, and repeated at irregular but frequent intervals--of a simple isolated or complex movement, which represents objectively an act intended for a particular purpose.

Curiously enough, however much this definition emphasises the clonic element in tic, Cruchet makes a subdivision into habit tics and convulsive tics, of which the former "are exactly comparable to normal movements, except that they are involuntary at the moment of their execution, are performed for no reason or purpose, and their frequency is unusual." Their difference from convulsive tics is merely one of degree; a habit tic may become a convulsive tic, and some are convulsive from the beginning. A habit tic, if the movement be a slow one, is closely allied to the "attitude"; and it is not always practicable to draw a distinction between them.

Thus Cruchet himself admits that the clonic element in tic may be minimal, so that the differences between him and our authors are by no means so insuperable as might be imagined. What he calls a habit tic is equivalent to the stereotyped act of the others, who hold, it will be remembered, that the movement of tic differs from the normal movement not merely by being involuntary, irresistible, inapposite, and so on, but also by being exaggerated.

It cannot be denied that in many cases of tic this exaggeration of the normal movement is anything but obvious; many conform absolutely to the definition of Meige and Feindel, except that the movements are not violent, or grotesque, or "caricatures." To withhold the term "tic" on this account would be rather unfortunate, especially since no standard exists whereby to estimate exaggeration. Enough has been said, however, to demonstrate how insignificant are the discrepancies between the rival definitions.

Another question recently raised by Cruchet is the possibility of the persistence of tic during sleep.

The evidence he has adduced in favour of this has now been accepted, as far as tics of the neck are concerned, by Meige. They are leas abrupt and less frequent, it is true; otherwise, they are identical with the movements of the waking hours. A case of a hiccoughing tic persisting in sleep has come under my own observation within the last few months. Now, it is not difficult to understand that a movement such as tic, which occurs during the conscious state in spite of the will of the subject, may arise when consciousness is diminished. In fact, one wonders why they are not more frequently remarked, seeing that they are habitual movements, and habit movements are by no means uncommon in sleep. It is highly probable, of course, that the observation of the watcher is not minute enough, but there is another reason. The peculiarity of all, or almost all, of these habitual movements in sleep is that they are rhythmical--we may instance the head nodding and head rolling of children; but it is a noteworthy fact that they are often regulated by respiration. When it is recalled how respiratory drill is eminently calculated to diminish the frequency and lessen the severity of very many tics, it will be admitted that the regularity of the respiratory movement in sleep is the most likely explanation of the infrequency of tic during that period.

One other matter may be shortly alluded to. In Cruchet's terminology, a tic is an anomalous gesture, and cannot be applied to an anomalous attitude, since the latter is tonic rather than clonic. For an anomaly of attitude he suggests the use of the word "deformity." Hence "habit deformity" is comparable to habit tic, and "convulsive deformity" to convulsive tic. As a habit tic may develop into a convulsive tic, so a habit torticollis may degenerate into a convulsive torticollis. There is no reason why the operation of habit as a factor should not effect the latter transformation exactly as it does the former; and as habit is held to be a psychical phenomenon, it is easy to conceive why the term "mental torticollis" should have arisen, and been so widely accepted. But it will be readily understood that while Cruchet affirms that no mental torticollis can ever be a tic, in his sense of the word, this is due solely to his refusal to consider any movement which is tonic as partaking of the nature of tic. In all other respects, the description which he gives of mental torticollis shows that it is nought else than a tic in Meige's sense.

In an article on convulsive torticollis which has been contributed by Meige to the _Pratique medico-chirurgicale_ (1907) he emphasises afresh the distinction between torticollis-spasm and torticollis-tic. The former is provoked by an irritative lesion in the motor nerves supplying the muscles of the neck, or in their nuclei of origin, and the character of the contractions ("contracture frémissante" [Meige], "contractions parcellaires," "contractions paradoxales" [Babinski]) in a definite peripheral nerve area is not likely to be mistaken. In other cases the objective phenomena distinctive of spasm are awanting: the characteristics of tic, on the contrary, are conspicuously present, and among these cases, where psychical disturbance plays a preponderant rôle, are to be found those described by Brissaud as mental torticollis.

It is to be noted that these writers alike decry the surgical treatment of torticollis, and perhaps not without good reason. Nevertheless the method must not be condemned on theoretical grounds merely, and it is permissible to believe that their experience may have been unfortunate. The records of the National Hospital provide many instances of surgical interference in torticollis and allied conditions of the neck, the results of which make one hesitate in expressing a dogmatic opinion. It is, however, impossible to enlarge further on the subject in this place.
