Consider here which way the vertebra is to be moved; if toward the right use right hand and if toward the left use left hand for adjusting. Draw the adjusting hand straight around until the first finger, about the middle of the proximal phalanx, rests against and _behind_ the transverse process. It is important that the finger be drawn _straight_ around, and not upward or downward, except with the second Cervical with which the finger may pass slightly upward to the transverse. To insure correct placing of finger let patient’s head be absolutely at rest, supported by the Hook Support with face turned slightly away from the adjusting hand. Reinforce contact finger with the other three fingers held close together behind it. The thumb may or may not be placed against patient’s jaw as desired, but one must be careful not to lose exact contact by drawing adjusting hand upward from a lower Cervical in an attempt to reach the jaw. Use of Second Hand Meanwhile the other hand supports the head and holds its weight as described under the Hook Support, q. v. Turning Head Next, holding the first finger gently but firmly pressed against the transverse process, turn the head in the direction of the subluxation and away from the adjusting hand. That is, if the vertebra be subluxated to the right turn the face toward the right, the use of the terms “right” or “left” referring to the spinous process. Movement When the head is drawn around so that the vertebrae are thoroughly separated on the side toward which movement is to be directed, and the patient’s muscles are thoroughly relaxed though it is felt that further rotation of the head would put them upon a tension, give the movement. It consists in a quick throw of the adjusting hand, force transmitted from shoulder through an outward fling of the elbow, directed upward and inward against the transverse process. It replaces the articular process against its fellow, moving one vertebra, smoothly and easily. _All_ force should be delivered with contact hand. The hand moves through very little space. The principle of the movement is transmitted shock. [Illustration: Fig. 13. The Rotary, No. 2.] THE ROTARY No. 2 A transition in technic between No. 1 and No. 3. Position Patient lies face upward on closed table, head resting upon forward section. Adjuster stands at side of patient, choosing the side according to the subluxation so as to face across the table in the direction toward which spinous process is to move. Palpation is difficult in this position on account of the increase in the curve of the Cervicals, so that it is best to follow a record previously made. Having found the subluxation make contact as follows. Contact
