The government of India recently announced a ban on homework! Can you imagine…a ban on homework? In an effort to promote student health and address recent surges in the incidence of back pain in the young, there will be no homework for students in grades one and two.
It was estimated that the majority of students ages 7 – 13 in India were carrying almost half their body weight. Not surprisingly, medical practitioners noticed a dramatic increase in reported cases of back pain among this group and decided to take action. In addition to the homework ban for grades one and two, Indian authorities have also implemented a limit of 10% of the student’s bodyweight.
Back pain in students is not unique to India. Each year, as students in the United States prepare to return to school from summer vacation, the subject of backpacks arises. The good news is, when compared to purses, messenger bags, or shoulder bags, backpacks are the best option to prevent lower back pain. The bad news is, most of the 40 million students in the USA using backpacks, are doing so incorrectly.
Studies have found more than 33% of children had LBP that caused them to miss school, visit a doctor, or abstain from activity. Also, 55% of children surveyed carried backpacks heavier than the 10-15% of their bodyweight, which is the maximum weight recommended by experts. Additionally, the study noted that early onset of LBP leads to greater likelihood of recurrent or chronic problems. Backpacks that are too heavy are particularly harmful to the development of the musculoskeletal system of growing youngsters. It can lead to poor posture that may lead to chronic problems.
The following information on backpack safely is based, in part, by guidelines from The American Physical Therapy Association. Parents and teachers would be wise to observe the following warning signs of an overloaded and unsafe backpack:
A. Change in posture when wearing the backpack
The weight of the pack forces the child to tip forward to compensate.
Weak or poorly fitted straps force the child to tip to the side to compensate
B. Struggling when putting on or taking off the backpack.
Due to a pack that is too heavy or straps that don’t fit properly.
C. Pain when wearing or after wearing the backpack
Due to a that is too heavy or straps that don’t fit properly
D. Tingling or numbness – in the arms or hands
E. Red marks – under the armpits or on the back
Consider the following suggestions to promote backpack safely and prevent back injury:
A. Limit Weight of Pack to 10-15% of Body Weight
(100lb child = 10-15lb pack)
B. Padded Adjustable Shoulder Straps
Use both straps to distribute weight evenly. Using one strap may look cool but it will lead to back pain.
C. Waist Belt
An adjustable waist belt will distribute pack weight from back to hips and legs
D. Pack Weight Distributed to Small of Back/Hips – using adjustable straps
Not all the weight on shoulders and upper back
E. Wheeled Backpack – if unable to make above adjustments
This is an option for some children; however, you may have problems carrying/lifting it on the bus etc.
F. Purchase Extra Set of Books And Use Your Locker
Get list from teachers and use the internet to buy extra books to leave at home. Teachers and students might consider downloading text books on the iPads or electronic tablets.
Also, put unnecessary books in your locker between classes
G. Remove Pack When Possible
While waiting for bus, hanging out between class, etc
H. Put Pack On/Off From Chair/Table/Bench – Not Floor
It is much easier to lift a pack up from a table and put it on your back than bending over to get it from the floor
I. Stand Erect and Arch Small of Back
The correct posture while carrying heavy items is to make a hollow or arch the small of your back
J. Perform Posture/Stretching Exercises
Pinch shoulder blades together and extend and arch your spine backwards intermittently throughout the day – especially every time you take your pack off
K. Consider a pack with multiple compartments
Use several compartments to carefully load your backpack and distribute the weight more evenly
L. Use a back with reflective material to enhance visibility.
