Abstract :
The pressures at the surface of the residual lower limb during ambulation are affected by the prosthesis fit and by the material choices in the prosthesis. This study is concerned with the design and application of a data acquisition system for use in studying the pressures in the below-knee amputee during ambulation. The goal was to develop a system that could be easily used with a number of patients and not interfere with the normal fit of the prosthesis. Data was collected from 10 patients, and demonstrated that the measurement system is capable of obtaining data using the patient´s own prosthesis. The system has potential for use in the improvement of material choice and prosthetic fit to reduce discomfort and tissue damage
