    Author(s): Myoung Kwon Kim39988*

    Purpose: This study examined the effects of the levels of resistance on the muscle activities around the hip and spine during bridge exercise with hip abduction resistance in patients with chronic back pain. Methods: A cross-over study design was used. Twenty subjects with low back pain were enrolled in this study. The subjects performed bridge exercise with hip abduction resistances (20 mmHg, 40 mmHg, and 60 mmHg). An elastic band was used to provide resistance. The surface electromyography device was used to measure the activity of the erector spinae, biceps femoris, gluteus maximus, and gluteus medius. The Root Mean Square (RMS) was calculated and the EMG signals collected were normalized to the percentage Maximal Voluntary Isometric Contraction (%MVIC). One way repeated measures ANOVA was applied to e.. Read More»
