Influence of prosthetic socket design and fitting on gait

Abstract

This chapter deals with lower-limb prostheses and, more specifically, the relationship between socket design and the quality of gait and mobility. Prosthetic sockets and suspension systems provide an intimate contact with the residual limb, and their interaction is important for overall comfort, fit, and mobility function. Even though technological advances have led to the enhancement of socket/limb interfaces, prosthesis users still suffer from a variety of problems, particularly related to the high and repetitive loading of the limb during gait. In this chapter, socket designs are reviewed, along with clinical issues relating to their use. This is followed by an examination of the effect of the socket/limb interface on the quality of gait. The chapter concludes with future perspectives and trends in prosthetic/limb interface approaches and technology.
