The SS22L torsiometer is a single output device used to measure axial rotation about a single plane (e.g., forearm pronation/supination). Telescopic endblocks compensate for changes in distance between the two mounting points as the limb moves. The gauge mechanism allows for accurate measurement of polycentric joints. Use TAPE2 medical adhesive tape to attach to the body. Requires one MP3X/45 channel for output.
The SS22L and SS23L single-output devices measure limb angular movement.
See SS21L and SS22L dual-output devices for simultaneous measurements around two orthogonal rotational axes (e.g., wrist flexion/extension and radial/ulnar deviations).
See SS24L single-axis goniometer to measure finger joint movement.
