摘要: Excessive loading due to daily backpack carriage in schoolchildren has been associated with increased risk of back pain. However, quantitative effects and carrying methods (anterior posterior) on the spine are still limited. Twenty seven participants, aged from 11 15, were recruited this study. They asked adopt a relaxed upright stance or without loaded at 15% their bodyweight either anteriorly posteriorly. Participants' spinal curvature repositioning ability measured using an electrogoniometric system. Repeated measures ANOVA showed that posterior resulted significant decrease lumbar lordosis increase cervical lordosis, while anterior induced thoracic kyphosis. Repositioning participants' was found reduce under carriage. Clinical implications these findings relation low pain adolescents deserved further investigation.
