What is the effect of the portable computer?
In our clinic we are becoming concerned at the increasing number of 9-17 year olds presenting with upper back and neck pain. One obvious cause is the extended periods of time children are spending on laptops, along with electronic gaming devices, in a poor postural position. Research from Curtin University demonstrates that an increase in computing time statistically results in an increase in neck pain
Many schools are asking all students of a certain age or year to purchase a laptop and the problems are compounded by a reduction in physical activity, particularly in year 11 and 12. Laptops are designed to use for short periods and spinal issues arise when used for long periods as the spine is held in a stooped posture. It is also common for children to use their laptop or tablet sitting on their bed rather than at a desk.
The following guidelines have been developed for the home use of laptop computers by children:
- Sit at a desk with a good office chair, not a lounge or on the bed
- Use a wireless keyboard and mouse.
- Elbows at 90 degrees and mouse close rather than reaching for it
- Position the laptop on a stand or similar so the top of the screen is at eye level and directly in front
- Take breaks at least every hour. Get up and move around.
- Feet should be supported on the ground or a footstool.
- Use document holders
- Teach children to report pain or discomfort. If it persists see a Physiotherapist
- Exercise regularly to counteract the effects of computing and electronic device use. Walking, swimming and stretching are all beneficial.

Remember, bad postural habits can develop at a young age. Prevention is always better than cure.
