Outline of Final Research Achievements

Although stroke survivors with hemiparesis need to relearn whole-body motion sensorimotor strategies, it is not clear whether they do so in a common manner. This study investigated dynamic balance control sensorimotor strategies in stroke survivors. Sit-to-stand movements were performed with restricted vision by hemiparetic and healthy control participants. When vision was restricted, the variability in the mediolateral center-of-pressure position decreased significantly in stroke survivors, but not in healthy controls (We evaluated the variability in the control theoretical sense.). Participants with hemiparesis adopted strategies that explicitly differed from those used by healthy individuals. However, variability may be decreased in the direction that most requires accuracy, and appropriate methods for collecting feedback may be set by each individual. This study suggests that stroke survivors adopt strategies appropriate to their individual characteristics.
