Choose the right one
Whether it’s about the cartoon character or the brand, backpacks are likely more about style than about function to our kids. So it’s up to us to do the heavy lifting when it comes to choosing just the right one.
Studies have used magnetic resonance imaging to examine what happens to children’s spines when they’re carrying backpacks of different weights. Reported back pain from higher backpack loads may be due to reduced lumbar disc height and greater lumbar asymmetry (more curvature).
A large-scale research study measured the weight and backpack load of 3,498 students and found the main predictor of back pain was the weight of the backpack relative to the student carrying it. The greater the disparity between the backpack weight and the wearer’s weight, the higher the chance the wearer would experience pain.
