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.
