Back pain is the most common health concern in recent times. Musculoskeletal pain is one of the major problems affecting the muscles and bones of the back body. Bad posture, overuse, injury, jerking-movements, falls, fracture, dislocations, and sprains are the main reason for musculoskeletal pain.  In recent times, school children are mostly affected by musculoskeletal pain as bag weight plays an important role in a child’s health. Thus, the identification of an optimum back bag is important to overcome the musculoskeletal pain which comes from carrying excess backpack weight. The conventional methods used are not practical to determine the optimum bag weight in real-time as it is a time-consuming analysis. Thus, Smart back bags are introduced to detect the optimum weight to avoid musculoskeletal pain are introduced. In this review, it is found that the technologies developed are capable of determining the total weight of the backpack determine the total weight of the backpack and notification to the user to adjust the bag straps according to the center of mass using the mobile application using different statistical techniques.
