Abstract: A prosthesis having a stump-receiving socket and a plurality of inflatable bladders with a means for the user to vary the pressures therein. The inflatable bladders each include a relatively soft, flexible membrane made of a suitable material such as polyurethane. The membranes are shaped to meet the anatomical characteristic of the wearer. Those membranes located adjacent the weight-bearing portions of the stump will provide a relatively soft uniform surface to support the stump. For those locations near the weight-bearing portions of the stump that should not be subjected to pressures, the adjacent bladder areas are non-inflatable and, therefore, not force inducing. The static pressures in the various bladders are independent of each other and may be regulated by the user.
