ABSTRACT:
A headpiece and headpiece coupling arrangement to be used in conjunction with a chiropractic treatment table, allowing the practitioner to select any one or more of six different modes of movement of the headrest relative to the main portion of the treatment table is disclosed. In addition to the somewhat conventional pivotal motion about a horizotal axis, the present invention provides the practitioner with pivotal motion about a vertical axis, linear extensin or traction, rotation of the headpiece about a longitudinal axis coinciding with the patient's spinal column, auxiliary flexion of the headpiece about a horizontal axis, and an abrupt limited motion for bringing a patient's head forward and downwardly, imparting a snapping action to the cervical spine. The latter two modes of movement are mechanically linked to the rotation of the headpiece.
