Online published on 16 October, 2018. Abstract Background/Objectives Compared muscle activity of gluteus medius and trunk muscle(External Oblique, Internal Oblique, Quadratus Lumborum) on the stability methods using compress belt(CB), lever bar(LB), tactile feedback(TF), biofeedback(BF) during a hip abduction exercise(HA).. Method/Statistical Analysis Twenty three subjects (8 male, 15 female) were mobilized for this research. The electromyography signal amplitude was randomly measured during HA, with BF, with TF, with LB, and with PB. The surface EMG signal was recorded from the internal oblique (IO), external oblique (EO), gluteus medius (GM) and the quadratus lumbolum (QL). Data were analyzed using a one-way repeated ANOVA.. Findings The muscle activity of GM significantly increased in LB condition than the HA and TF condition, the muscle activity of QM significantly decreased in CB condition than the TF condition, and the muscle activity of ratio of GM for QL significantly increased in BF condition than the HA and TF condition. For the muscle activity of right EO in trunk muscle, the BF condition significantly decreased then the LB, CB, and TF condition, and muscle activity of left IO of significant decreased in condition than the TF and LB condition.. Improvements/Applications BF may be useful to avoid uncontrolled movement during HA in sidelying position, through increasing the GM and decreasing the QL.
