Abstract: Nowadays, back belts are commonly used among industrial manual handling workers to prevent low back injury. This study aims to investigate how the lumbo-sacral belt and the pelvic belt affect trunk muscular activities during manual lifting. Both belts are elastic type but differ in the belt width and wearing position. Nine Japanese healthy male subjects whose ages range between 21 and 27 years participated in this study. The results showed that there were significant decreases (p =0.01) of Transversus Abdominis (TrA)/Internal Oblique (IO) and Erector Spinae (ES) activities when wearing the pelvic belt and lifting 20-kg loads using the squat posture, and lifting 20-kg loads using the standing posture, respectively. All other conditions showed similar trend of decreases in trunk muscular activities. © 2011 Taylor & Francis Group.
