Conventional patellar-tendon-bearing (PTB) socket/stump interface dynamic pressure distributions recorded during the prosthetic stance phase of gait of a trans-tibial amputee.

Force sensing resistors (FSR) have been used to measure dynamic stump/socke t interface pressures during the gait of a trans-tibial amputee. A total of 350 pressure sensor cells were attached to the inner wall of a patellar-te ndon-bearing (PTB) socket. Data was sampled at 150 Hz during the approximat e 0.8 seconds of prosthetic stance of gait. A total of 42,000 pressures wer e recorded during a single prosthetic stance. This paper describes the dist ribution of the pressure patterns monitored during the prosthetic stance ph ase of gait.
