Ultrasound pre-study of the kinematics of the residual tibia within a trans-tibial socket during gait

Abstract

The motion of the residual-tibia within a trans-tibial socket was examined so far only by X-ray. In this pre-study now the motion of the residual tibia is to be described during gait using ultrasound data. The results of measurement raised here are to serve as input for later simulation work, in order to be able to adapt socket fit individually. So far, this procedure of ultrasound measurement during gait cycle was used only related to the femur. In the first part the structure of the test rig and the integration into the socket is described, as well as the calibration of the system. In the second part, the results of measurement are represented and discussed afterwards. © 2009 Springer-Verlag.
