One of the serious problems the current generation children and adolescents are facing is the problem with the bad back posture. During their early schooling period, the body growth is relatively stable and the balanced body posture during the period of seven to eight years of age is dominant. However, when the child begins its schooling, the time spent in sitting position is extended than before which can result in disorders of posturogenesis. Hence, this period is defined as “The first critical period of posturogenesis”. According to latest literatures, this problem affects between 40% and 70% of children in developed countries. Excessive load on back causes lifetime back pain and spinal deformities in children. The pain associated with carrying a backpack is referred to as “backpack syndrome”. This syndrome includes the factors like, abnormal body posture causing headaches, fatigue, cervical and lumbar pain and structure of body. This paper focuses on the main cause of the back pain (i.e) the structure of backpack. To reduce the load on the body initial stress values are required which are generated using FEATool unlike other journal papers where they make use of experimental data and analytical calculations. The results of analysis proves that if the total body weight is distributed over a large portion instead of only back portion the values shows a significant changes after using specially designed models compared to commercial backpack.
