There are many different ways of imparting suggestions to a hypnotized subject; and as, in the other phases of hypnotism, hysterical patients present the greatest variety of manifestations, when subjected to suggestive influences. The most characteristic phenomena are those known as "muscular" suggestions. If we analyze an emotional attitude, such as that of sending kisses to a loved person, or that of threatening an enemy with the fist and outstretched arm, we notice that the whole frame takes part in the special action. The eyes dilate, the muscles of the face move, and an appropriate play of the features accompanies the leading gesture. This collaboration of several parts of the body in the production of a common effect depends upon the existence in our nervous system of certain mechanisms subservient to the function of mimetic language or physical expression. Now if in the hypnotized subject we throw a limb into such an expressive attitude, we immediately see the usual concomitants of the movement follow suit; the trunk and other limbs fall into a harmonious posture, the carriage of the head is modified likewise, and the expression assumed by the face and eyes is so perfect as to equal or surpass the best efforts of the most consummate actor. It is difficult for any one who has not witnessed the spectacle to realize the perfection of mimicry reached by the hypnotized hystero-epileptic. The cause of this phenomenon is not far to seek: the impression conveyed by the nerves from the part placed in the attitude has called into action the whole nervous mechanism presiding over the movements generally associated with this attitude. But this is not all. Duchesne has analyzed minutely the anatomy of the expression of the human face, and by means of electric currents localized in certain muscles or combinations of muscles, imitated with great success the facial play indicative of the various emotions and feelings of the mind. Now if in our subject we likewise electrically stimulate certain muscles, and artificially produce an expression of anger, or terror, or love, or disdain, the corresponding attitude is at once assumed by the neck, arms, and body generally. Those of our readers who have access to the book will find remarkable illustrations of these phenomena in Dr. Richer's beautiful work,[1] for the accuracy of which all those who have had the opportunity of studying hypnotic manifestations in hystero-epileptics will be ready to vouch.
Whole series of muscular actions may be initiated by appealing to the so-called "muscular sense" by similar methods of suggestion. Thus, if a hanging rope is placed in the hands of the patient, she begins to climb with incredible energy and alacrity; when placed on all-fours, she runs in that position all over the room, regardless of knocks and collisions. Or, if the movements of washing with invisible soap be communicated to her hands, she will persist in the mimicry for an indefinite time. It is sometimes difficult to check an action so started
