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. 本文描述的是假肢系统、装置及其使用方法。通常，假肢可以构造成基于步态的阶段对假肢关节的转动设置阻力。假肢可包括第一缸、可在第一缸内滑动的第一活塞、流体槽和流体回路。流体回路可包括多个互连的流体通道，其具有单向可变阻力阀和一组止回阀，该组止回阀构造成在活塞压缩和伸展期间提供通过可变阻力阀的单向流动。
