Abstract Purpose of the study: This study aimed to investigate the effect of carrying unilateral backpack on dominant and non-dominant sides on posture in female adolescents and to determine the effect of age on postural alignment. Methods: Seventy five adolescent female students participated in this study. Their age ranged from 12-18 years. All students were assessed using formetric instrument system under three conditions; during carrying backpack on dominant, non-dominant side, and without carrying any load. The outcome measures include trunk variables (trunk imbalance, inclination and inclination angle), pelvic variables (pelvic tilt, torsion, rotation and inclination), spine angles (maximum kyphotic and lordotic angles) and deviation variables (lateral deviation RMS, maximum lateral deviation and surface rotation). Results:The results showed statistically significant differences in all measured variables with exception of kyphotic, lordotic angle and pelvic inclination variables during the three testing conditions with greater differences in loading condition on dominant than non-dominant side |
