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.
