The immediate effects of a novel auditory and proprioceptive training device on gait after stroke

This is totally pathetic, no mention of what they did, a metronome? And what was the proprioceptive device?

This case report describes the immediate effects of a new rehabilitation tool on gait in a chronic stroke patient. Specifically, we measured step length symmetry and gait velocity in a 47 year-old male stroke patient who was currently receiving outpatient physical therapy. Objective gait measurements were taken using the GAITRite before, during, and after a 5 minute training session. Step length symmetry improved 26% during the first minute of training, 71% by the fifth minute of training, and 72% after a 5 minute rest period post-training. Gait velocity increased by 5.5% after 5 minutes of training. Clinical research is warranted to validate this new training tool as a useful adjunctive rehabilitation activity for improving spatial and temporal aspects of gait after stroke.
