Abstract: A pelvic traction belt for transmitting a longitudinal traction force and a rotary traction force through the pelvic area to the spinal column of a human wearer located generally in the supine position. The pelvic traction belt includes a circumferential section for encircling the pelvic area of the wearer with the circumferential section having opposing end portions constituting the front of the circumferential section when being worn and a back portion intermediate the end sections. A traction tail is included as an integral part of the back portion of the circumferential section and depends generally perpendicular therefrom for communicating generally upwardly between the legs of the wearer for transmitting the longitudinal traction force and the rotary traction force through the pelvic area to the spinal column. Fasteners are included for removably securing the end portions of the circumferential section around the pelvic area of the wearer.

Abstract: The range of motion that an individual can move his head or other body portions can be measured and recorded in an apparatus having a base with a plurality of switches mounted thereto in a plurality of predetermined positions with each switch being actuated by movement of the base as the individual moves his particular body part through available angles in predetermined directions. The switches actuate a display board, having lights and/or a graph, to maintain a display of the available range of motion the individual can move his head or other body portion.
