Musculoskeletal-model based prosthetic gait evaluation for orthopaedic applications using low cost motion capture equipment

Abstract

Gait deviations caused by amputation of the lower limb create an altered gait pattern and rehabilitation of the gait will need to correct these deviations [1, 2, 3]. While assessing prosthetic gait it is important to know how normal gait in the amputee is affected. To date objective analysis of gait, pre and post to prosthesis fitting has required access to motion capture equipment found only in major hospitals and research institutions. However a new generation of inertial measurement unit based motion capture equipment has significantly reduced cost to those affordable by private prosthestists and orthotists. This paper examines the practicalities of using this equipment to generate results of value to these clinicians.
