Abstract
[Purpose] We investigated the factors strongly associated with the step-over action post-stroke hemiplegia patients. [Subjects] The subjects were 18 post-stroke hemiplegia patients in the maintenance phase who could walk independently outside. [Method] We measured the step-over action with obstacle heights of 10, 20 and 30% of the trochanter malleolar distance, and performed simple regression analysis to determine the relationships between the maximum step-over height and the knee extension strength of the hemiplegic and unaffected sides, the stance times of both legs, trunk impairment scale (TIS) scores, time since stroke onset, and age. Then, with maximum step-over height as the objective variable, and the four items with the highest r2 values in the simple regression analysis as explanatory variables, we performed multiple regression analysis. [Results] TIS and the unaffected side knee extension strength were identified as explanatory variables with a contribution ratio of 71.9%. [Conclusion] The results suggest that among the items investigated in the present study, trunk function contributes the most to the performance of the step-over action.
