Just in time for school, The American Physical Therapy Association is reminding kids and parents of the proper ways of wearing a backpack.
Doctors associated with the organization say overloaded and heavy backpacks, or backpacks that are worn improperly, can increase the risk for pain and musculoskeletal injury.
Experts recommend students use both straps on their backpacks, and keep the load to 10-15% of the child's weight.
Warning signs that your child could be at risk for back injury include a change in posture when wearing it, struggling when putting it on or taking it off and feeling a tingling or numbness in the arms and legs. Red marks on the shoulders are also a sign that your child’s backpack is too much to bear.
