A gait rehabilitation pilot study using tactile cueing following hemiparetic stroke

Recovery of walking function is a major goal of post-stroke rehabilitation. Audio metronomic cueing has been shown to improve gait, but can be impractical and inconvenient to use in a community setting, for example outdoors where awareness of traffic is needed, as well as being unsuitable in environments with high background noise, or for those with a hearing impairment. Silent lightweight portable tactile cueing, if similarly successful, has the potential to take the benefits out of the lab and into everyday life. The Haptic Bracelets, designed and built at the Open University originally for musical purposes, are self- contained lightweight wireless devices containing a computer, Wi-Fi chip, accelerometers and low-latency vibrotactiles with a wide dynamic range. In this paper we outline gait rehabilitation problems and existing solutions, and present an early pilot in which the Haptic Bracelets were applied to post-stroke gait rehabilitation.
