Abstract

Background: Epidemiological evidences have showed that low back pain fallowing load-carrying is the most common disorder in musclo-skeletal system and is common in industrialized countries. Moreover, little is known about how muscles are recruited when several option of the accomplishment of task are available. Thus this study aimed to examine the effects of EXTERNAL LOAD and TRUNK POSTURE on the electromyography activity of TRUNK MUSCLES.Materials and methods: 10 healthy women with no history of low back pain were enrolled in this study. Two inclinometers and five channel EMG system were used to evaluate the right trunk muscle activities (rectus abdominis, internal & external oblique, erector spine, and multifidus). Six static tasks while holding three levels of load (0, 6, 12 Kg) in two trunk position (neutral and 30 degree of flexion) were simulated for subjects.Results: With highest EXTERNAL LOAD, the electrical activity of back and abdominal muscles increased significantly and with highest trunk flexion, the electrical activity of back muscles increased significantly (P<0.05).Conclusions: Co-contraction of back and abdominal muscles occurred in response to greater need for biomechanical stability. The increased extensor muscles activity during trunk flexion is necessary for stability and controlling of flexion.
