Cable-Operated Transradial Prosthesis

INDICATIONS/BENEFITS

When considering the benefits of body-powered control, it is necessary to make a distinction between body-powered hooks and hands. Body-powered hooks are very functional for a variety of activities. They are lightweight, relatively low cost, and simple in design. Hooks have proven to be very functional and are especially well suited for use for heavy-duty activities. They are less prone to damage in excessively dirty, wet, and corrosive environments than externally powered devices are. Body-powered hands, however, do not have these same attributes, as will be discussed below. Body-powered control offers good proprioceptive feedback through the cable and harness system. This type of feedback has been described as extended physiological proprioception where the control system provides feedback regarding force, position, and velocity of the prosthetic component.
