Upper Extremity Dummy Design
The instrumented upper extremity has seen several design changes since its inception in the mid-1990s. The most recent modifications were made to the wrist and forearm. In order to evaluate better the wrist loads expected from interaction with a door mounted hand grip, a two-axis load cell was added to the distal forearm to measure wrist bending moments. The range of motion of the wrist joint was modified to increase its biofidelity. In addition, the forearm was modified to include the ability for mid-shaft pronation as well as a potentiometer to measured this rotation.
