A pre-prosthetic training device is provided. The device provides an interim prosthetic device that aids in the standing, weight bearing, and balancing exercises during post-surgery rehabilitation therapy that are required before a prosthesis fitting. The device includes a residual limb support for receiving the residual limb of an amputee, an adjustable pylon for adjusting the height of the residual limb support, and a support base including a plurality of support legs for providing support to the pylon and residual limb support. The residual limb support includes a cushion having a recessed portion sized to receive the distal end of the residual limb of an amputee and for providing comfort and stability thereto. The residual limb support further includes an upper open end and a sidewall including a tapering portion that provides vertical and lateral access, respectively, of a residual limb into the residual limb support.

A prosthetic device comprising an upper member, and a lower member having a conical terminating section, the conical terminating section fitting into a conical void defined in the upper member. A prosthetic device kit, comprising an upper member and a number of lower members each having a conical terminating section in which the conical terminating sections of each lower member fit into a conical void defined in the upper member.

An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.
