Subjects were asked to step forward, sideways, or backward, in response to a stimulus light signal with the left or right leg under a cane-free and a cane (regular type)-assisted condition. In the cane -assisted condition, healthy subjects used the dominant hand and patients with stroke used the unaffected hand to hold the regular cane. To date, 8 (6 young and 2 older) healthy subjects have participated in this study. Reaction time, movement time, step length, and the force dynamics of the cane were calculated. The results showed that older adults benefited from using the cane by decreasing the reaction time and increasing the movement time of the stepping responses. The force dynamics of the cane were task-specific, suggesting that even for healthy adults, the use of a cane still provides additional physical support for the completion of the stepping movement. These preliminary results will serve as important reference information to be compared with as we collect more data on hemiparetic patients following stroke.application/pdf187553 bytesapplication/pdfzh-TW國立臺灣大學醫學院物理治療學系暨研究所hemiplegiaambulation assistive deviceattentionstepping during standingdynamic equilibriumreaction timemovement timeforce dynamicsjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/25631/1/912314B002365.pdf
