|
Purpose:The purpose of this study was to investigate the effects of maximum muscle activation of lower extremity of facility dwelled elderly Hansen’s disease after isometric trunk exercise for 12weeks.
Methods:18 elderly Hansen’s disease who isometric trunk exercise for 12weeks were recruited for this study. They were instructed to perform maximum muscle activation of lower extremity after exercise. and the subjects were divided into normal sensory group, sensory loss in left foot group, sensory loss in right foot group and sensory loss in both feet group, according to the sensory condition ability on their soles.
Results: After exercise, Hamstring muscle increased significantly (p<.05), and activation of the rectus femoris muscle decreased with a significance (p<05). In terms of Post-hoc test for examining the difference in MVIC according to sensory condition, there was significant difference in the normal sensory group, sensory loss in right and left foot group of left hamstring muscle before the exercise(p=.01) and the normal sensory group, sensory loss in both feet group of right hamstring muscle before the exercise(p=.04).
Conclusion:These results indicate that the maximum muscle activation was changed after isometric trunk exercise. it could be improved maximum muscle activation of lower extremity muscle after the exercise although there was sensory loss.
