Effect of Backpack Weight on Postural Angles in Pre-Adolescence School Children

In order to minimise postural unbalances and injuries of preschool adolescents, the present experimental study was earned out on 7th class students of private sector schools of Meerut. Total 30 students, 15 (50%) boys and 15 (50%) girls students aged between 10 to 13 years were participated. The effect of backpack load carrying on posture was assessed to measure the angles as Craniovertebral angle (CVA), Craniohonzontal angle (CHA) and Saggital shoulder posture (SSP). In this study six treatments were included in static condition with dynamic loading (without backpack, different modes of carrymg own backpack as over right shoulder, a both shoulders and 10 %, 15 % and 20 % backpack weight of reference body weight). Results revealed that there was small effect on CHA and CVA angle of boys and girls were affected when they earned 20 % of their body weight backpack with p value 0.020 in comparison with unloaded condition. SSP of girls and boys were affected due to the position of carrying in comparison with unloaded state. While carrying more than 10 % body weight, the SSP angle increased that lead to change in the shoulders as extension or more rounded shoulder if the forward head posture is increased.
