Abstract
Described here are prosthetic systems, devices, and methods of use therefor. Generally, a prosthesis may be configured to set a resistance to rotation of a prosthetic joint based on a phase of gait. The prosthesis may include a first cylinder, a first piston slidable within the first cylinder, a fluid sump, and a fluid circuit. The fluid circuit may include a plurality of interconnected fluid channels having a unidirectional variable-resistance valve and a set of check valves that are configured to provide unidirectional flow through the valve during piston compression and extension.
