Aching back and shoulders, weakened muscles, tingling arms, stooped posture. Does your child have those symptoms after wearing a heavy school backpack? Carrying too much weight in a pack or wearing it the wrong way can lead to pain and strain.
Recent studies have begun to examine how school backpacks effect children and adolescents. A review of the research published within the past 5 years reveals that incorrect backpack use leads not only to back pain in youths, but also impedes proper physiological growth and functions. The adolescent spine continues growing in periodic spurts until the age of 18, making the proper use of backpacks vital. More than 7,000 emergency room visits in 2008 were related to backpacks and book bags. Half of those injuries occurred in children 5 to 14 years old. Students on average carry 22% of their body weight, exceeding the recommended 15%. And 34% of students carry more than 30% of their body weight at least once during the week.
Injury occurs when a child tries to adapt to the heavy loads and uses faulty postures such as arching the back, bending forward, or leaning to one side. These postural adaptations can cause improper spinal alignment which hampers functioning of the disks that provide shock absorption. A backpack load that is too heavy also causes muscles and soft tissues to work harder leading to strain or fatigue. This leaves the neck, shoulders and back more vulnerable to injury.
A heavy load may also cause stress or compression to the shoulders and arms. Make sure that both shoulder strap are always worn. Wearing a pack slung over one shoulder can cause a child to lean to one side, curving the spine and causing pain or discomfort. If the nerves are compressed, the child may experience tingling or numbness in the arms.
When worn correctly and not overloaded, a backpack is supported by some of the strongest muscles in the body: the back and abdominal muscles. These muscle groups work together to stabilize the trunk and hold the body in proper postural alignment.
