Abstract: A cable tensioner for a wearable item includes a rotatable dial, a rotatable reel that receives a cable wound therearound, a fixed portion, and a gear mechanism rotatably coupling the rotatable dial and the rotatable reel. The rotatable dial and rotatable reel are rotatable relative to the fixed portion. The rotatable dial is axially movable relative to the fixed portion between a first position, wherein the gear mechanism has a first gear ratio, and a second position, wherein the gear mechanism has a second gear ratio less than the first gear ratio. The first gear ratio has a value such that rotation of the rotatable dial permits fine adjustment of the rotatable reel and that the gear mechanism resistively holds a tension in the cable. The second gear ratio has a value that permits coarse adjustment of the reel and that the gear mechanism releases a tension in the cable.

Abstract: A prosthetic system includes an inner socket configured to receive a residual limb, the inner socket having at least one socket window, and an outer frame configured to receive the socket, the frame having at least one frame window. The socket window is configured to align with the frame window when the socket is received within the frame. The frame window and the socket window are together configured to releasably receive a sensor for the residual limb.

Abstract: An outer frame for a prosthetic limb is provided. The outer frame is formed from one or more parts and has a plurality of air flow openings.
