Abstract
A unique 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 five 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 horizontal axis the present invention provides the practitioner with pivotal motion about a vertical axis, linear extension or traction, rotation of the headpiece about a longitudinal axis coinciding with the patient's spinal column and an abrupt limited motion for bringing a patient's head forward and downwardly, imparting a snapping action to the cervical spine portion.
