A locking coupler device for connecting a residual limb socket to a lower limb prosthesis is provided having a body with a top mounting surface, a bottom mounting surface, an anterior area and a posterior area. The top mounting surface is adapted to connect to the residual limb socket at a defined location on the top mounting surface. The bottom mounting surface is adapted to connect to the lower limb prosthesis at a defined location on the bottom mounting surface. The top and bottom mounting surfaces are horizontally offset such that a longitudinal centerline of the residuum limb socket is located from about 0.5 to about 4.0 inches anterior of a longitudinal centerline of the lower limb prosthesis when the residual limb socket and the lower limb prosthesis are attached to the top and bottom mounting surfaces, respectively, of the coupler device. In addition, the top mounting surface is inclined posterior to anterior at an angle from about 5&#xb0; to about 20&#xb0; relative to the bottom mounting surface.

Prosthetic angled locking coupler device

There is provided a mechanical orthotic device and method. The orthotic device and method utilize a torsion spring to provide resistance to restrain pivotal movement of upper and lower members between an extension and a flexion position.
