Backpack and back health is a concern. With school ending and summer sales beginning, parents are already looking for new backpacks. Backpacks come in all shapes, sizes and themes. Because of their design, they are supported by strong muscles in the back and abdomen. However, depending on how heavy, the pack can cause back pain from overweight or from incorrect use.
Backpack Problems
The recommendation for carry weight by doctors and physical therapists is 10% to 15% of a student’s body weight. However, most students carry more weight in the packs than recommended. Thus, the force of the weight pulls the wearer backward. Sometimes, the weight causes the student to arch the back. Therefore, causing the spine to compress unnaturally and cause pain. In compensation for the overweighed backpack, the student tends to bend forward at the hips.
Too heavy of a pack can also distort the natural curve in the middle and lower back. This cause strain and irritation to the joints and rib cage. Another problem is the tendency to round the shoulders to pull the balance forward, thus causing a fall.
Carrying a backpack over the shoulder is harmful. This causes muscles to strain to adjust to the uneven weight. Therefore, the spine leans to the opposite side.
Consider The Fit
Backpacks must have a proper fit for each child. It must have a cushioned back and wide shoulder straps to prevent aches and pains from occurring. Additionally, the backpack must have a waist strap. The waist strap distributes the weight of the pack more evenly. Consider not only the fit but also the material. Leather packs are heavier than canvas. And, as the student is walking to school, a pack with reflective strips make the child noticeable to drivers.
Risk or Not
Presently there is no evidence of spinal deformities resulting from the use of a backpack. In addition, there is no evidence of a permanent injury from carrying a heavy backpack. However, it does not hurt to take all precautions necessary to keep students safe from physical injury. Children must be encouraged to wear backpacks properly.
