Abstract
Backpack carrying has been described as the most typical daily loading condition for children and adolescents, with concerns raised by parents, educators and health care professionals on the role of heavy backpacks in the development of spinal pain. The application of a backpack load to the body results in a number of adaptations, including increased muscular effort, increased physiological demands, increased psychosocial stresses and postural adaptations. The resultant postural changes are primarily aimed at maintaining the body's line of gravity within its base of support, and include forward shift of body segments. This study investigated the effect of three loads (3%, 5% and 10% of Body Weight) in two backpack positions (high and low) on three postural angles (lower trunk, trunk and neck on trunk) in young and older female adolescents. The results suggest a differing postural response between the trunk and the neck with increasing backpack loads. Differences in postural responses were also identified between high and low-carried backpacks, and between older and younger female subjects © 2010 by Nova Science Publishers, Inc.
