Use of a powered foot may result in less sound and residual knee pain and increased patient-reported mobility in transtibial amputees compared to a passive foot. The results are consistent with established biomechanical mechanisms of knee unloading and warrant consideration in patient care.

Study with the aim to investigate how different prosthetic feet influence trunk angles during gait in transtibial amputees (TTA). Six TTA, six controls, three feet analysed during -5°, 0° and +5° gait. Feet show small differences for trunk angles, but with probably no influence on lower back pain.

This paper gives insight into the heel-region properties of different prosthetic feet with a new test method and contrasts the results of quasi-static tests as reported in the state of literature with roll-over results generated using a novel machine-based test method.

Der der Schuh ist ein Teil des prothetischen Systems und der Schuhabsatz kann den Prothesenaufbau beeinflussen. In dieser Studie werden die biomechanischen Auswirkungen von kleinen Änderungen in der Absatzhöhe untersucht.

A novel prosthetic foot with polycentric ankle has been developed to provided frontal plane adaptability. Here various performance metrics are quantified and compared to six comparison feet using standardized mechanical tests.
