Hydraulic/pneumatic external knee prosthesis

Definition

A device which is a component of an external lower limb prosthesis designed to functionally replace, in part or total, an absent knee, wherein the principle of operation for motion control is based on hydraulics and/or pneumatics (e.g., using fixed fluid orifices, or needle or servo valves). It responds to changes in motion by providing variable damping through progressive adjustments [i.e. over several steps] in motion resistance. It may have various designs and functional features (e.g., monocentric or polycentric, manual lock, stance flexion) for support during a variety of activities.
