For a right subluxation turn the face toward the _left_ and use _right_ hand for contact hand. For a left subluxation turn the face to the right and use left hand for contact hand. Contact Thumb of contact hand is placed upon and against the side of the spinous process so that it presses firmly. The thumb is extended almost at right angles to the hand which rests upon the patient’s shoulder with fingers extending, and gripping, over the clavicle. Be sure of the solidity of the position. Next place the other hand upon the patient’s forehead and press the head backward, or toward the side of the contact hand, until the neck is well flexed and the tissues tightened between the now opposing hands. [Illustration: Fig. 19. The “T. M.,” No. 1.] Movement When this tightened condition is reached a quick decisive movement of _both_ hands in opposite directions, but chiefly of the hand applied to the head, will secure an easy movement of the vertebra. This move is a very valuable adaptation of the old crude and other dangerous “T. M.,” of which No. 2, below, is another, more like the original move but possessing several “safety” features. “T. M.” No. 2 Position of Patient The patient sits erect on a flat seat with both feet resting upon the floor as during palpation. Placing Hands After careful palpation and selection of a vertebra to be adjusted in this way, stand directly behind the patient. If the vertebra is subluxated to the right use right hand for adjusting (or contact) hand, if to the left use left hand. Hold the hand so that the thumb is at right angles to the hand and tense and firm. Place the palmar surface of the end of the thumb against and upon the tip of the spinous process and grasp the neck firmly with the fingers, which extend over the base of the neck and toward the clavicle. The other hand is placed easily on the top of the head. Position of Head The completing of position after contact has been made is governed by two considerations; the need for relaxing the neck muscles and for so supporting the vertebrae above the contact that movement will take place only at the point of contact. If the neck muscles are contracted the movement is almost always defeated and should always be abandoned to avoid strain. To secure the desired position ask the patient to relax his muscles and allow you to place his head as desired. If he seeks to place it himself the necessary muscular contraction on his part will defeat the movement. The movements of the head must be passive.
