Abstract

Wrist function is essential for correct positioning of the hand; however, few available prosthetic wrists provide powered flexion/extension. Users must compensate for this lack of function by performing compensatory body movements that may cause injuries and lead to device abandonment. Using the Gaze and Movement Assessment (GaMA) metric, we evaluated task timing, endpoint trajectories and 3D angular joint kinematics when using a 1-DOF wrist compared to a 2-DOF wrist in combination with a 1-DOF hand. We hypothesized that with the 2-DOF wrist, kinematics would be more similar to normative data and that users would perform fewer compensatory movements than when using the 1-DOF wrist.
