Abstract

The purpose of this study were to examine the effect of two different pelvic alignments and the back belt on electromyographic(EMG) activity of the erector spinae during lifting. The results were as follows: 1) EMG activity of erector spinae was greater when the pelvis was tilted anteriorly than when the pelvis was tilted posteriorly during lifting. 2) EMG activity of erector spinae was greater when the back belt than when without the back belt during lifting. These results suggest that the greater EMG activity of erector spinae with an anterior pelvic tilt position and with back belt during lifting may ensure optimal muscular support for the spine while handling loads.
