Abstract:
1. A device for measuring a subject's trunk rotation in a seated position, the device comprising: a frame attached to a seat wherein the frame elevates the seat from ground; a bracket, directly attached to the frame; a measuring arch, directly attached to the bracket; wherein the bracket spans a geometric center of the measuring arch, the bracket being coplanar with the measuring arch; a main arm comprising a first end and a second end, the main arm being coplanar with the measuring arch and the bracket, the first end of the main arm rotatably connected to the bracket at the geometric center of the measuring arch; a secondary arm, rotatably attached to the second end of the main arm and extending past the measuring arch; and a pole connected to the secondary arm, the pole being perpendicular to a plane defined by the measuring arch, bracket, and main arm; wherein movement of the pole about the geometric center of the measuring arch enables measurement from the measuring arch to provide the measurement about a subject's trunk rotation.
