Abstract

Introduction: The object of this study was evaluation electrical activity of trunk muscle in chronic LOW BACK PAIN patients during holding load.Material and Method: Ten women with chronic LOW BACK PAIN 20-25 years old and ten healthy women were participated in this study. Five channel EMG systems were used to evaluate the right trunk muscle activities (rectus abdominis, internal and external oblique, erector spine, and multifidus). Six static tasks while holding three levels of load (0,6 and 12 Kg) and two levels of trunk position (neutral and 30 degree of flexion) were simulated for subjects.Results: Results of this study showed that %MVC of internal oblique in patients with LOW BACK PAIN is less than healthy during loading 6 and 12 kilogram in neutral trunk position. In addition, %MVC of external oblique in patients with LOW BACK PAIN is more than healthy during loading 12 kilogram in flexed trunk position (P<0.05).Conclusion: Higher activation of global and lower activation of local abdominal muscle may represent that pain changes muscle motor program. Therefore exercise therapy in these patients must lead to improvement function of motor control system.
