With thumb and remainder of adjusting hand properly placed, use the other hand upon the head as follows: First flex the head forward on the chest as far as possible, then rotate it slightly so that the face is turned a little toward adjusting hand. Then flex the head sidewise until a resisting pull of muscles indicates that they have been stretched taut. It is well during the third movement described to let the forearm swing down at right angles to the hand so that it presses firmly against the ends of all the Cervical transverses, distributing the force among them. Or, after placing contact hand rest the elbow in the angle at the base of the neck and let the forearm extend upward along the side of the neck. Then flex the wrist until the hand will rest upon the patient’s head and perform the movements of the head as described above. [Illustration: Fig. 20. The “T. M.,” No. 2. Note position of right arm and hand of adjuster.] Movement A quick, simultaneous movement of both hands in opposite directions, _two-thirds_ of which is given with the hand which holds the head. The thumb in contact with the spinous process moves slightly inward toward the median line but its chief use is to hold the vertebra very firmly. To this end part of its force is directed forward against the shoulder and through the ball of the thumb. Failure to place the head properly or in securing sufficient flexion of the neck before move is attempted are the chief causes of failure. Force must be delivered quickly and sharply and the best adjustment of this kind is usually the one in which the head and hands move through the least space. Uses This movement is obviously useful only for the correction of _rotation_, since the force is directed sidewise against the spinous process. The “T. M.” was originally intended as a Cervical adjustment, but its greatest use is now from C 6 to D 2 inclusive. Above the sixth its use is questionable because of the possibility of moving more than one vertebra or some other than the one desired. “THE RECOIL” (Pisiform Contact) Position of Patient This movement is best given on bifid bench of the type commonly known to the profession. Place patient on forward section so that its rear edge rests just below the axilla; this may be ascertained by passing a hand under patient’s arm after he is in position, when the edge of the bench should be felt about an inch below the hanging arm. The thighs should rest on rear section so that the pubic symphysis is free of the bench. The semicircular pubic cut is an advantage in that it avoids injury without making necessary too great a suspension between sections. Thus the abdomen and the lower part of the thorax are suspended between sections. Under them an abdominal support may be used but it must have the quality of elasticity in a high degree and must lie always below the plane of the other two sections or it will interfere with a perfect adjustment.
