Effect of Backpack of 10% of the Body Weight on Cervical and Shoulder Posture for School Going Childrens

The backpack is one of the several forms of manual load carriage that provides versatility and is often used by bikers, backpackers and soldiers, as well as school students. However, musculoskeletal problems associated with backpack use have become an increasing concern with school children . The combined effects of heavy load, position of the load on the body, size and shape of the load, load distribution, time spent carrying, physical characteristics and physical condition of the individual were hypothesized as factors which were associated with these problems experimental study, same subject design was used for the study. Two experimental load conditions (static and dynamic loading with 10% body weight) were tested. The subject unloaded posture is compared with posture under two different experimental loading conditions. Result: No significant difference was found between unloaded state and static loading posture p value is greater than 0.05.
