BACK TO SCHOOL SAFETY: AVOIDING BACKPACK INJURY
Tips for helping your kids to wear their backpacks safely
Despite parents best efforts to protect their children from getting hurt,
one of the greatest sources of potential injury often gets overlooked even when its in plain sight: the
backpack. Considered the most efficient way to carry books and other items that kids need for school, when
its overstuffed, it may actually be causing the pain and fatigue that as many as 50 percent of kids today are
experiencing.
Although there are a number of causes for back pain in school-age children, many kids are carrying
backpacks that weigh more than 15 percent of their body weight, said Avrom Gart, M.D., a Medical
Director at the Cedars-Sinai Institute for Spinal Disorders. Over time, children carrying this kind of weight
can develop serious back pain and other problems that can require treatment.
Compared to satchels or briefcases, backpacks are typically safer for kids because they distribute weight
evenly across the body and are supported by the back and abdominal muscles. Furthermore, children and
teens prefer them because they are fashionable, hold more items, and come with multiple compartments that
help them to stay organized.
But despite their usefulness, a major study reported by the American Physical Therapy Association has
found that more than 50 percent of children surveyed carry backpacks heavier than 15 percent of their body
weight.
To manage the load, children sometimes arch their backs or lean forward, causing them to develop poor
posture as they grow, said Dr. Gart. Children should carry no more than 15 percent of their body weight
on their backs.
Wearing a backpack on one shoulder can also cause the child to lean to one side to compensate for the extra
weight and can result in an asymmetrical spine, back pain, and a strained shoulder and neck. In severe cases,
children can develop a condition called scapular winging, when the nerve that supplies the shoulder
muscle becomes pinched, causing paralysis.
If you notice that one of your childs shoulder blades is not moving or not symmetrical, a doctor should be
consulted immediately, said Dr. Gart.
To help your child wear backpacks safely, Dr. Gart recommends the following:
1. Wear no more than 15 percent of your body weight. Work with your child to determine how
much weight should be carried in his or her backpack. Weigh each item separately, so that your
child can determine which items should be carried versus what can be left at home.
2. Keep backpack use limited to necessities only. See that your child cleans out his or her backpack
daily by removing any items that can be left at home or in a locker.
3. Use both straps. Make sure that the weight of your childs backpack is evenly distributed across
the back to promote good posture and to avoid shoulder strain and/or a pinched nerve.
4. Recognize signs that the backpack is too heavy. Pay attention to whether your child is slouched
or leaning to one side when wearing a backpack or is experiencing any type of back pain, tingling or
numbness in the shoulders or arms.
5. Select the proper backpack. Enhance comfort and safety by purchasing a backpack with multiple
compartments, so that weight is more evenly distributed. Padded straps can also help to prevent
straps from cutting into shoulders. Newer backpacks with wheels are also an option, provided that
the handle extends long enough to allow children to stand upright while pulling it. The backpack
and wheels must also be sturdy enough so that it does not topple over.
6. Pick up the backpack properly. Teach your child how to pick up his or her backpack by
demonstrating how to bend at the knees and grasp the pack with both hands before putting it on.
Kids and parents alike need to remember that while backpacks are a great tool to carry and keep track of
items children need for school, they must be used properly to avoid injuries, commented Dr. Gart.
