Using swing resistance and assistance to improve gait symmetry in individuals post-stroke.

Human movement science Jun 10, 2015
A major characteristic of hemiplegic gait observed in individuals post-stroke is spatial and temporal asymmetry, which may increase energy expenditure and the risk of falls. The purpose of this study was to examine the effects of swing resistance/ass...
