Optimal Design Of A Myoelectric Socket For The Through-Shoulder Amputee
Repository Usage Stats
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
