    Fitting The Humeral Level Brachial Plexus Amputee With Externally Powered Myoelectric Control
    (1999) Stevens, Gordon; Farnsworth, Troy
    Brachial plexus injuries present unique challenges to both the patient and prosthetist, The brachial plexus injury can be classified in many categories: complete or incomplete lesion, with either an intact or amputated limb as a result of the injury. The intact yet flail limb presents with lack of sensation, shoulder subluxation, severe pain, and is often subjected to unintentional burns and cuts. Many brachial plexus patients with an intact limb elect to undergo limb amputation to reduce complications or improve function with prosthetic fitting options. Unforttmately, some patients continue to experience similar post-amputation complications. Fusion of the shoulder joint is a surgical option in an attempt to decrease pain and reduce shoulder subluxation. This procedure may be performed before, after, or in association with amputation of the extremity.

    Optimal Design Of A Myoelectric Socket For The Through-Shoulder Amputee
    (1997) Stevens, Gordon
    The traditional shoulder socket is a cap over the shoulder which leads to gapping of the myoelectric contacts. An improved socket design leaves the upper aspect of the socket open and achieves suspension on a wedge formed by the upper back and upper chest The wedge guarantees excellent myoelectric contact at all times. The socket is finther stabilized by a lateral strut and a T-section that surrounds the cage lower rib. All other areas are left open. When combined with a new X-shaped Neoprene suspension, this socket permits the free motion of the acromion to be used for adjusting the terminal device in space and for activating secondary devices such as mode selection switches or separate controls for wrist motion. This socket design has been tried on both a bilateral shoulder patient and a transradial/shoulder amputee. FINAL PAPER NOT RECEIVED AT PRESS TIME
