Can Simple Electronic Instrumentation Associated with Basic Training Help Users of Assistive Devices? - Presenting and Verifying the Effectiveness of a Biofeedback Module for an Instrumented Crutch

Abstract

Crutches are prescribed towards compensating lower limb overload and adding sensory information through upper limb. However, adequate loads are required to avoid upper limb lesions and further lower limb injuries. Therefore, this work describes the development and application of a biofeedback module for a Lofstrand crutch, based on a simple electronic instrumentation. The goal is to train the user to apply proper load on the crutch. Basic training was performed by healthy subjects before and after static and dynamic activities. Results showed the feasibility of the device and the effectiveness of the training to reach the target (load on the crutch of 20% of body weight).
