1P1-D07 Walking support robot "Tread Walk" for alleviating asymmetricity of hemiplegic walk : Effect of walk speed difference with separated treadmill

Abstract

Hemiplegia is one of the main squeals of stroke. As for the hemiplegic walk, weight load on affected side decrease. The ability of loading weight on affected side has strong correlation in standing balance and walking performance. Therefore, it is need to load weight on the affected side actively. This study targets developing walking support robot which alleviating asymmetricity of weight load in hemiplegic walk. As a method of alleviating the asymmetricity, deferring speed of right and left belt in separated treadmill was contrived. To validate this method, walk of subjects who simulate hemiplegia was analyzed with separated treadmill. As a result of the analysis, decreasing speed of simulated affected side belt make single support phase of affected leg and double support phase increase and weight load on affected side further. From this result, it is guessed that decreasing speed of affected side belt for real hemiplegic patient can further the weight load to the affected side.
