Abstract:

A jacket which functions as a measurement tool for providing information regarding the flexural conduct of the wearer. The jacket has a plurality of self-contained electrical measurement devices mounted thereon, each of which is designed to measure the angle of tilt of a particular portion of the spine in an act of leaning. In a preferred embodiment, the jacket has three clinometer frames which project through slots formed in the rear of the jacket so as to be positioned adjacent the sacrum, lumbar and thoracic portions of the spine. Mounted in each clinometer is an electrical measurement device which responds to changes in its axial angle to vary its electrical output signal proportionately. In a preferred embodiment, the electrical measurement device comprises a gravity-actuated potentiometer which utilizes a movable mercury contact as an angle sensing means. Each clinometer is individually powered and has its output response fed to a gauge which may be easily visually observed by the wearer.
