Carrying a Backpack at the Right Height to Prevent Functional Scoliosis in Children

When you see your child walking with a slouched posture while carrying a heavy backpack, it’s not only concerning for their appearance but also increases the risk of developing Functional Scoliosis. While this condition doesn’t cause the spine to curve as in Scoliosis, it can lead to chronic back pain in the future.

Functional Scoliosis arises from imbalances in the body, such as unequal leg lengths or from carrying weight on one side of the body for extended periods. Over time, this creates a habit that strains the muscles of the back and the spinal joints, particularly during movement, causing chronic injury. Repeated stress may lead to pain in the shoulders, back, and neck, and this issue can persist as they grow.

‘kdms’ shares these important reminders for parents to ensure backpacks are properly adjusted for their children’s posture. The weight of the backpack should not exceed 15% of the child’s body weight, and the positioning of the backpack should be in line with their natural body structure.

 

 

Proper Backpack Position

• A: Level with the shoulder blades. If the weight of the backpack pulls at the neck area, it could cause neck pain.
• B: Level with the upper back (thoracic spine). This is the most ideal position for the backpack.
• C: Level with the waist. This creates impact forces on the lower back and may lead to back pain.

Additionally, consider choosing a backpack with hip straps or chest straps to distribute weight evenly and reduce pressure on any one area. This can also help the child move more freely.

If using a side sling bag is necessary, it’s better to wear the strap diagonally across the body instead of on just one shoulder, as this will reduce strain on one side of the body.
Once the bag is packed according to the school timetable, remember to check the backpack every morning before your child carries it to school or embarks on a field trip. Always adjust the straps so they fit the child’s body properly to protect their shoulders and back in the long run.
