Abstract :

This study is designed to analyse the effect of mass and type of school bag on shoulder musculature among school going children of age 10-14 years. This work consists of two phases. In first phase questionnaire based study was conducted on 70 students in three schools of Kangra, districts of Himachal Pradesh. Visual Analog Scale was used for pain rating. It was found that 25 persons have had significant shoulder pain. Using these 25 data Artificial Neural Network has been trained with the help of Feed Forward Back Propagation Technique. Type of backpack and ratio of backpack weight to the body weight of school going children were considered as input variables, however pain generated in shoulder was taken as output variable. Further a predictive model was developed after training the network. Backpack with wide padded shoulder and padded back was found to be significant in reducing the shoulder pain through both the observed and predicted value.
