การทรงตัวในผู้สูงอายุAbstract
Background and Objective: Falling in the elderly is one of the major health problems affecting their daily life including walking. The declines in gait speed and stride length with aging could contribute to an increased risk for falling. This study aimed to determine the effects of the rhythmic auditory stimulation (RAS) at different frequencies on gait speed, stride length, cadence, and balance in healthy elderly.
Methods: Thirty-six healthy female elderly were recruited in this study. Ten-meter distance was used in all participants under four walking conditions (subject’s preferred walking speed, RAS+10%, RAS+20% and RAS+30%). Timed up and go test was assessed in all participants after each walking condition.
Results: The gait speed, cadence and balance performance of RAS+10%, RAS+20% and RAS+30% walking were significantly higher compared with subject’s preferred walking speed condition (p<0.05). The stride length of RAS+20% and RAS+30% walking increased significantly compared with subject’s preferred walking speed condition (p<0.05).
Conclusion: Higher frequency of RAS than normal subject’s walking speed could improve gait speed, stride length, cadence and balance in elderly. The findings of this study might give a further insight into application of RAS as an intervention to improve walking ability in elderly.
