Prosthetic wrists need to be compact. By minimizing space requirements, a wrist
unit can be made for people with long residual limbs. This prosthetic wrist uses
two motors arranged across the arm within the envelope of the hand. The drive is
transmitted by a differential so that it produces wrist flexion and extension,
pronation and supination, or a combination of both. As a case study, it was
controlled by a single-prosthesis user with pattern recognition of the
myoelectric signals from the forearm. The result is a compact,
two-degree-of-freedom prosthetic wrist that has the potential to improve the
functionality of any prosthetic hand by creating a hand orientation that more
closely matches grasp requirements.
