People with neurological disorders often experience problems with their balance and gait. To improve the gait capacity orthotic devices, like ankle-foot orthoses (AFOs) and orthopedic footwear, are prescribed. To improve prescription of these orthotic devices, this research investigated the assessment of effects of orthotic devices on gait capacity (part 1) and evaluated the effects of orthopedic footwear on gait capacity (part 2). In part I we showed that movement sensors are a reliable method to measure the shank-to-vertical angle (SVA), an important outcome measure for AFO alignment. The SVA measured with the movement sensor was valid and responsive to changing heel heights, and was equivalent to 3D gait analysis. Part 2 showed that orthopedic footwear improved the gait capacity in people with Hereditary Motor and Sensory Neuropathy (HMSN). With orthopedic footwear people with HMSN walked faster, with larger and smaller steps, and were better able to adapt their gait.
