ABSTRACT:
A method for testing for dysfunctional discs in which a spinal contact member contacts a disc under a low force to obtain the position of the contact member with the disc in its normal or usual unstressed position, the same disc is contacted with the contact member under an elevated increased standard force to obtain a second position of the contact member, and the two positions are compared to determine the condition of the disc. A complete contour of the spine is obtained and recorded. Apparatus used includes a roller which bears against the spine and rolls from disc to disc with the roller being mounted on a vertical calibrated rod. Means are provided to vary the pressure applied to the rod.
