Unlabelled: Carrying heavy backpacks are often associated with shoulder discomfort or pain, loss of sensorimotor functions, and brachial plexus injuries that might hamper performance. On the basis of previous research, the cause of these symptoms could be tissue deformations of the brachial plexus and the subclavian artery caused by the shoulder straps.
Purpose: This study aimed to evaluate the changes in the upper extremity hemodynamic and neural function and to assess how they are associated with brachial plexus tissue deformation during heavy load carriage.
