Introduction

Various rehabilitation shoes are prescribed to protect the forefoot following surgery. Patients often complain of discomfort in other areas as a result of the postoperative shoe, including the knee, hip and lower back. This has never been quantified. This study aims to establish the effect on other joints using gait analysis. Methods: 11 healthy volunteers were investigated using various common types of postoperative shoe. They were studied with gait analysis equipment and the joint motion assessed with commercial software. The effect of commercial devices designed to minimise gait changes by lifting the contralateral foot were also evaluated.

Results

There was a reduction in knee flexion and extension compared to the contralateral leg in all phases of the gait cycle. This was the case with both heel wedge shoes and inflatable air boots. There was also an increase in pelvic tilt during gait with both shoes, which was more pronounced with the air boot. The foot raise device for the contralateral foot which is designed to decrease these changes was effective in decreasing gait changes.
