A novel, portable 64 channel surface array stimulator

Array stimulators have been proposed as a solution to the difficulty reported by patients in finding the correct stimulation site. Array stimulators for transcutaneous use have typically be restricted to a few channels switched to individual array elements via multiplexing circuits, their use outside the laboratory has not been reported. In order to investigate the clinical utility of array stimulation a device is required that may be used at home. The current device is currently been used with stroke and MS patients in a gait lab based pilot study, and will later be used in patients homes.
