力感电阻（FSR）已被用于测量经胫骨截肢者步态过程中的动态残肢/窝界面压力。总共有350个压力传感器连接在一个水铸插座的内壁上。数据以150Hz的频率采样，采样时间约为0.8秒。Convery和Buis（1998）报道的手铸套内动态压力分布与水铸套内监测的相同截肢者的动态压力分布进行了比较。水铸臼内的压力梯度小于手铸髌骨-肌腱承载（PTB）臼内的压力梯度。手铸型PTB套管内近端高压“环”被水铸型套管内远端高压取代。
Force sensing resistors (FSR) have been used to measure dynamic stump/socket interface pressures during the gait of a trans-tibial amputee. A total of 350 pressure sensors were attached to the inner wall of a hydrocast socket. Data were sampled at 150Hz during approximately 0.8 seconds of prosthetic stance of gait. The dynamic pressure distributions within a hand cast socket reported by Convery and Buis (1998) are compared with those monitored within a hydrocast socket for the same amputee. The pressure gradients within the hydrocast socket are less than that of the hand cast Patellar-Tendon-Bearing (PTB) socket. The proximal “ring” of high pressure in the hand cast PTB socket is replaced with a more distal pressure in the hydrocast socket.
