(HealthDay News) -- A heavy backpack can lead to pain and injury when a child doesn't wear it properly.

The American Academy of Orthopaedic Surgeons suggests how to avoid improper use of a backpack:

  • Wear both shoulder straps.
  • Make sure both straps are tight.
  • Don't overload the backpack, and keep it well-organized.
  • Take out items you don't need.
  • Work on strengthening back muscles.
