Abstract

This study explores the function of a 2-degree-of-freedom (DOF) prosthetic wrist compared to a single-degree-of-freedom wrist for people with below-elbow amputation. The study involves five participants who wore a custom-made 2DOF wrist system and an Ottobock Transcarpal hand, using pattern recognition-based control. Participants did in-lab tests in two conditions: wrist rotation only and wrist rotation with flexion/extension. Functional outcomes, including the Southampton Hand Assessment Procedure, Box and Blocks Test, Jebsen Taylor Test, Activity Measures for Upper Limb Amputees, Clothespin Relocation Task, and Assessment for Capacity of Myoelectric Control, were measured. Preliminary results show little difference between the two conditions, possibly due to the additional addition length, mass, or control complexity.
