Prostheses, Upper Limb, Hook, Myoelectric
Definition : Hook prostheses operated by myoelectric power and designed for partial functional replacement of a missing hand. These prostheses are typically external devices made of metal (e.g., cobalt-chromium alloys), hard plastics (e.g., polyethylene), carbon fibers, or a combination of materials; they may include totally or partially implanted components (e.g., sensors, electrodes). The prostheses are usually fixed with a socket to the wrist and require some degree of customization. Myoelectric controlled hand prostheses typically incorporate small electrical motors and electrodes within the socket to pick up electrical signals that trigger hook operation as the muscles in the residual limb contract. They may be used alone as a replacement for a missing hand or as the terminal component of a below-the-elbow, above-the-elbow, or total upper limb prosthesis in patients who have congenital abnormalities or who suffered amputations due to illness (e.g., diabetes) or traumatic accidents.
