Effects of Backpack Weight on Biomechanics of Adolescent Below-knee Amputees During Walking

Adolescents often carry backpacks exceeding the recommended 10% of their body weight, leading to postural abnormalities and musculoskeletal pain. These biomechanical changes, especially during gait, are well-documented in non-amputee population, but the effects on adolescent amputees remain unclear. This study examines how heavy backpacks lead to exaggerated compensatory postural strategies in adolescent below-knee amputees, significantly increasing the risk of musculoskeletal injuries. The findings underscore the need for tailored rehabilitation, prosthetic designs, and education to mitigate long-term health risks.
