Effects of Lumbar Stability Exercise on the Muscle Thickness and Contraction Time Using Sound Wave Vibrator and Swiss Ball
Abstract Purpose The purpose of this study was to investigate the effects on the muscle thickness and contraction time using sound wave vibrator and swiss ball. Methods This study was performed on 20 subjects. 20 subjects were divided into two groups; Lumbar stability exercise using sound wave vibrator exercise(n=10)(Group1) Lumbar stability exercise using Swiss ball exercise(n=10)(Group2) Both of the group performed the exercise 3 times a week for 5 weeks. The data was analyzed by the paired t test to compare before and after difference of factors on each group and the Independent t test to compare the between groups. Results Both group were increased muscle contracture time on Straight Leg Rise(SLR) test (p 0.05) Conclusion As a result of this study, we suggest that the sound wave vibrator may be effective exercise tool for lumbar stability exercise like a swiss ball.
