A walker boot is preferable to two other ankle devices for improving pain and gait after internal fixation for ankle fracture, according to research from the University of Oxford in the UK.
Investigators analyzed 18 patients six weeks after surgery under three ankle device conditions: a walker boot, a stirrup brace, and an elastic sleeve.
The stirrup brace and, to a greater extent, the walker boot were associated with less pain and single-limb support time asymmetry than the sleeve. The walker boot was also associated with a significantly wider step width than the sleeve, which may improve gait stability.
The findings, epublished in January by the Journal of Orthopaedic & Sports Physical Therapy, contrast with those of a similar December 2015 study of healthy individuals by the same research group. In that study, published by the Journal of Electromyography & Kinesiology, gait asymmetry was significantly worse in the walker boot than the two other devices.
