- Abstract
[Purpose] Deep muscles of the trunk are attracting attention because of their involvement in motor control and as proprioceptors. The aim of this study was to examine the effects of exercise intervention focusing on these muscles on postural sway. [Subjects] Twenty patients who could stand and walk independently participated in this study. [Method] Subjects were assigned randomly to perform one of two motor tasks: drawing in the abdomen, or leg exercise. Postural sway was measured using center of pressure (COP) before the intervention, and exercise was performed for 3 min. Subjects rested for 3 min, then COP was measured again. COP before and after the exercise was compared between the two groups. [Results] In the group with the task of drawing in the abdomen, significant decreases were observed in total length of COP, envelope area, and rectangular area, and a significant increase was observed in length/envelope area ratio. In the leg exercise group, no significant changes were seen between before and after the intervention. [Conclusion] These results suggest that exercise intervention for deep muscles of the trunk may help to stabilize postural sway.
