The movement is a quick drawing toward the adjuster of the second, or contact, finger, which has been, as it were, hooked over the transverse. The transverse is thus drawn sharply forward and the vertebra rotates around its vertical axis so that the spinous follows, or tends to follow, the transverse in the same arc of movement.
ROTARY No. 3
Position
Patient sitting erect, both feet evenly on floor and hands not braced. Stand in front of the patient but to one side or the other as for Rotary No. 2. Use right hand for adjusting right subluxations and left hand for lefts.
Contact
As for No. 2, contact is with palmar surface of second finger but may be shifted to third finger for the lower vertebrae if desired. The thumb is usually placed on the mandible and aids the opposite hand, placed on the other side of the head, in turning and otherwise controlling the head.
Movement
Turn the head away from the adjusting hand until the neck muscles feel taut as a result of position and not of contraction. The movement then is given as a sharp jerk of the contact hand forward.
