Description

Regular use of heavy school bags and inappropriate carrying methods can put children at the risk of musculoskeletal problems and changes the body posture. It is imperative to note that carrying a backpack more than the recommended weight limit poses a twofold hazard, particularly to children and adolescents who are undergoing neuromusculoskeletal development and growth. Hence, it is crucial to ensure that the backpack's weight does not exceed 10-15% of the child or adolescent's body weight. Overreaching this weight limit may result in posterior displacement of the center of gravity, thereby engendering augmented strain on the neck and back muscles. Such effects are commonly linked with spinal column pathologies and reduced lung volume.One of the most prevalent types of postural anomaly is called "forward head posture" (FHP), and it is typically characterized by the head being anterior to the body's vertical line gravity point. Chronic FHP issues develop from an excessive load being placed on the joint and muscle when cervical muscular imbalances brought on by postural misalignment are left untreated. Both an upper cervical extension and a lower cervical flexion define forward head position. These modifications in the cervical region could result in long-term bad head posture, which could cause "upper crossed syndrome" or other musculoskeletal disorders. Additionally, neck and shoulder pain are common complaints among FHPs patients . Numerous studies have shown that carrying a backpack that is 7.5% of or more of your body weight (BW) causes postural compensations. The increased weight of the backpack correlates with higher FHP, trunk flexion, spinal asymmetry, and tensile forces in the intervertebral discs under static settings
