Computer ergonomics
Understanding good computer ergonomics is important. Lots of research points to sustained sitting postures as a source of simple lower back pain. Poor keyboard posture can also lead to other problems too such as neck and shoulder pain and forearm and hand problems.
One of the easiest things you can do to try and reduce postural stress and strain is to sort out your work station and get your computer ergonomics as well optimised as possible.
Here are a few simple rules you should follow:
- Get a decent chair!
I have met so many people who manage with any old thing; the chair should fit the person, so experiment with different types as not all chairs will suit you. A key point though, if you are using a conventional chair, make sure it has a good solid base, is height adjustable and that you can alter the angle of the backrest.
Make sure your lower back is well supported, either with a lumbar roll or by having a decent support already built into the chair.
Or you could try something very different. There are lots of different types of ergonomic chairs around, some, like this kneelsit chair, helps reduce back pain by encouraging you to sit up tall and take some of the weight into your shins. This particular chair looks very interesting as it allows forward and backward movement too.
- Make sure your feet are on the floor or up on a footrest.
- Your head should be in a neutral position with your screen at about 15 degrees below eye level.
To achieve this you must have an adjustable monitor, both for tilt and for height. If you have to twist or turn to see your monitor this is very bad news!
- Try and keep your forearms at about 90 degrees and supported on the desk top or a wrist rest.
Your upper arms should be relaxed and vertical if possible.In order to achieve this your keyboard needs to be separate.
- Don’t work for long periods using a notebook or laptop.
Unless you have a separate keyboard and mouse and can get the laptop monitor up to a decent height you will never get good computer ergonomics using a portable machine.
- Don't share.
I find that often in offices, people share chairs and computer workstations. Whilst this is not always avoidable it is not good practice either. Everyone is different and your workstation should be set up for just you. Failing this, take time to readjust each time you use the computer gain – it will be worth the effort.
- Talk to your workplace occupational health team.
Employers have a responsibility to keep you safe, that includes making sure your computer ergonomics are correct for you. Many companies will offer a computer ergonomics assessment and give advice tailored to you.
