摘要

Objective: This study examined the effects of target distance and trunk restraint on reaching performance in persons with stroke. The second aim was to investigate the impact of the clinical characteristics of persons with stroke on motor performance. Methods: Twenty-five persons with stroke used less-affected arm to perform an upper-extremity reaching task under four experimental conditions: near distance with trunk restraint, far distance with trunk restraint, near distance without trunk restraint, and far distance without trunk restraint. Results: Significant and large effects of target distance and trunk restraint were found on increasing shoulder and elbow joint ranges (p＜.01, r=.72-.97). Movement smoothness was improved under condition of trunk restraint and target placed in near distance (r=.43). Conclusions: The results of this study indicated that the individual characteristics and physical environment influenced reaching performance. Participants with left brain damage and with more severe neurological impairment showed deficits in trajectory control. The ability of trunk control affected the temporal performance of reaching movement. Findings of this study suggest that treatment and evaluation should be tailored to clinical characteristics of persons with stroke.
