摘要: The application in some embodiments relates to a magnetorheologically actuated prosthetic knee (112) . one embodiment comprises an extension assist (148) facilitate extension. another flexible diaphragm (146) that substantially prevents or mitigates undesirable pressure build-up the chamber. yet specially configured dynamic seal (162a) is utilized magnetorheological fluid comprising liquid and solid particles within chamber of knee. Advantageously, allows amputee move comfortably, safely natural life-like manner various static states, terrains topography.
