Abstract

Introduction: laptop bag may be a contributing factor for musculoskeletal complaints in schoolchildren. Several studies have reported an association between carrying heavily loaded schoolbags and musculoskeletal pain or discomfort. Methods: 105 collegiate students were conveniently recruited in this study. Electromyography (EMG) signals were recorded during the treadmill walking at a speed of 4-5km /hour for 20 minutes with the load. The data were recorded in back pack, right side pack and left side pack with both right & left upper trapezius. Results: Paired sample t test was used to find out the significance level of EMG activity and result showed significant differences in right side pack and left side pack. Conclusions: EMG activity of right trapezius exhibited increased in subjects with right side pack, left trapezius was increased in subjects with left side pack, but in back packs the increment of right & left trapezius EMG is almost equal.
