What causes RSI?

RSI can be caused by:

  • Repeating the same sequence of movements many times an hour or day.
  • Static posture, sitting in the same position for hours on end.
  • Having to work very fast, under pressure.
  • Having to use appreciable force.
  • Lack of control over the order of tasks or working methods.
  • Working in awkward or tiring positions.

Your muscles tighten up when you are under stress. Continuing to work intensively under these conditions will increase the likelihood of developing RSI-type symptoms.

RSI can produce what is called 'referred pain'. This where you feel the pain in a different part of the body to the one that is causing it. So tightened and sore muscles in the neck can cause pain in your hands, fingers, wrists and forearms.
