영문 초록

This study examined whether any changes by mental task types on postural control in chronic stroke persons. Sixteen chronic stroke persons (mean age=53.75 yr) and sixteen age-and gender-matched healthy controls (mean age=54.44 yr) took part in this study. Participants randomly performed three different tasks on the stable and unstable surlaces. The no mental task was to stand while holding a 100 g weight in each hand, the arithmetic task (mental task) was to perform a silent I-backwards counting while standing and holding a 100 g weight in each hand, and the simple task (mental task) was to stand and hold with both hands a tray (200 g) on which a glass filled with water has been placed. Sway path and sway velocity of the center of pressure (COP) were measured to assess standing postural control by task performance using the force platform According to the results, in stroke group, total sway path and total sway velocity of COP was significantly decreased during arithmetic and simple task compared to no mental task on the stable surlace (p<.05), and sway path (anteroposterior AP, mediolateral JVIL) of COP, total and sway velocity (AP, JVIL, total) of COP was significantly decreased during arithmetic and simple task compared to no mental task on the unstable surlace (p<.05). Especially, sway path (AP, total) of COP and sway velocity (AP, JVIL, total) of COP was significantly decreased under the simple task when compared to the arithmetic task on the unstable surlace (p<.05). In healthy control group, sway path (AP, JVIL, total) of COP and sway velocity (AP, JVIL, total) of COP was significantly decreased during arithmetic and simpIe task compared to no mental task on the stable and unstable surlace (p<.05), and sway path (AP, total) of COP and sway velocity (AP, JVIL, total) of COP was significantly decreased under the simple task when compared to the arithmetic task on the unstable surlace (p<.05). In conclusion, the findings of this study showed that arithmetic and simple task improved standing postural control for chronic stroke patients and the type of arithmetic and simple tasks were critical factor that reduced standing postural sway in dual- task conditions. Future research should determine whether dual-task conditions, including simple task, would be effective as a training program for standing postural control of stroke patients.
