Gait study finds FES of plantar flexors fails to improve mechanical recovery

Functional electrical stimulation of the plantar flexor muscles in addition to the dorsiflexors surprisingly had no effect on mechanical recovery during post-stroke gait in a study performed at the University of Delaware. Researchers analyzed the effects of dorsiflexion FES alone … Continue reading

Diabetic boot bests TCC for offloading forefoot area but not for ulcer healing

A cast-boot ankle foot orthosis decreases plantar pressures under the forefoot more effectively than a total contact cast, but its relative effectiveness for ulcer healing is still a function of compliance, according to research from Washington University in St. Louis. … Continue reading
