Abstract: A prosthetic appliance disposes a plurality of elongated, resilient members in a circular configuration around a pivot point representing a skeletal joint such as an ankle, wrist or shoulder. The resilient members are resilient and adapted to deformable respond to pivoting forces of the fulcrum, and forcibly deform in response to the pivoting of the shaft forcing the fulcrum against the resilient members. The circular orientation of the resilient members pivot the shaft orthogonal to the base from which the resilient members extend, such that the resilient members bias the fulcrum and shaft in the orthogonal position at a rest position. Forces drawing the shaft off-center disposed the fulcrum against one or more of the resilient members and causing resilient deformation and counterforces against the fulcrum back to the centered rest position. In response to pivoting movement, the resilient members apply increasing forces for biasing the pivoting shaft.
