Fall is on the way, and so are school buses and students carrying…backpacks. You might not
think much about those bags full of books, pencils, crayons, and computers, but physical
therapists do.
Why Backpacks Matter
Students will always have things to carry between home and school. A backpack is a great way
to do that, but if they’re too heavy, they can cause problems.
Research has shown that carrying a heavy backpack changes students’ posture, walking speed,
step length, and more. Unsurprisingly, we also know that as students walk greater distances
and become more fatigued, these changes worsen.
These changes can lead to neck pain, back pain, or other musculoskeletal issues.
How Heavy Is Too Heavy?
How much weight a student can safely carry is directly affected by their weight.
Studies have shown that changes in posture and performance start to occur when the backpack
weighs 10% of the student’s body weight. Experts agree that students should not carry more
than 15% of their body weight in a backpack.
Unfortunately, most data show that more than half of students carry more than the
recommended load.
5 Tips for Parents and Students
To reduce backpack weight and help your student avoid pain, here are a few tips:
1. Plan ahead – Each night, go through the backpack and remove items not needed the
next day. Likewise, ensure your student doesn’t bring things home they won’t need that
night.
2. Use your locker – Planning ahead can help remove extra weight between home and
school. The locker can lighten the load during the school day. Students can avoid
carrying extra loads during the school day by making a few stops at their lockers.
3. Pack right – Heavier items should be placed close to the student’s back, and lighter
items should be placed further away.
4. Wear it right – Using both shoulder straps and front or hip straps, if you have them,
helps distribute the load evenly. The bottom of the pack should be even with the bottom
of the low back. Packs worn too high or low exaggerate postural changes and can
restrict movement.
5. Pick the right pack – If you’re shopping for a new backpack, look for one with two straps
rather than one. A chest strap and hip belt can help distribute the load. The pack should
also be sized appropriately – no longer than the student’s torso.
You can’t control what your student needs for school. However, you can use these tips to help
reduce your student’s load and ensure that they carry it correctly.
If your student is having pain in their back, neck, or anywhere else, call their physical therapist
today. They can help!
