Healthy Hints - Repetitive Strain Injury (RSI)

View Product »


Repetitive Strain Injury (RSI) or Carpal Tunnel Syndrome (CTS) is a painful condition caused by long-term incorrect and repetitive use of nerves & tendons.  So when using a computer for long periods of time whether for a job or fun you may find yourself performing hundreds if not thousands of small repetitive actions.  Therefore it is important to be aware of any discomfort, particular in the hands, arms, neck or back as these may be an indication of RSI that requires professional medical advice.

Symptoms of RSI can include:

  • pain or tenderness in muscles or joints
  • cramp
  • swelling
  • tingling, throbbing or numbness
  • stiffness
  • weakness

However, there are certain actions you can take that may reduce the chance of this becoming a problem.

The information displayed here should not be considered as official advice but is rather a generalization of recommendations from around the World.
IMPORTANT: If you feel that you may be experiencing any health issues you should always seek advice from a health professional such as a doctor or optician.

Frequent Breaks

Frequent Breaks

Try to take frequent breaks from your computer work.  This will give your body time to recover from being in a static posture.  More information about the benefits of taking frequent breaks is available here.

Keyboard Wrist Rest

Typing Technique & Products

When using the keyboard it is recommended that you keep your wrists in line with your forearm.  Adopting the touch-typing technique can also help to minimize your hand movements.  Products are also available that can help from keyboard and mouse wrist rests to ergonomic keyboards.

Touch Screen

Alternative Input Devices

There are number of alternatives to using a standard keyboard and mouse that can help change which muscles and tendons you use.

  • Speech Recognition Software

    Although probably not suited to busy offices, speech recognition can be used to either enter text or to control the computer and thus reduce mouse and keyboard usage.

    This ability is even available free in popular editions of Windows:

    Windows 7 & Windows Vista, can be found under:
    All Programs » Accessories » Ease of Access » Windows Speech Recognition.

    Windows 8, can be found under:
    All Apps » Windows Ease of Access » Windows Speech Recognition.

  • Alternatives to the Mouse

    Switching to a different pointing device can result in using different muscles and tendons and thus may give those currently being used a rest.  Such alternatives include trackball, track pad and touch screen.  Some computer mice also have additional side buttons; consider re-assigned their actions to perform left and right clicks thus changing which fingers are used.

Clipboard

Switching Tasks

If your job relies on performing different tasks, try not spending too long performing any particular one.  Instead, try varying your activities, preferably with non-computer related tasks, such as paperwork, discussing work topics with fellow colleagues or tidying your work area.

Automating Tasks

Automating Tasks & Shortcuts

By automating even the smallest computer actions, you can reduce the number of mouse and keyboard clicks while also becoming more productive.  Such automated tasks can include:

  • Browser Favorites
    Creating Web Browser favorites or using its history avoids having to re-enter the web address or search term of frequently visited sites.  This is also useful for avoiding typos that can result in going to the wrong and sometimes malicious places on the Internet.
  • Macro Recorders
    Office based programs such as Word Processors and Spreadsheets usually offer the ability to create Macros or record keystrokes.  These can then be used to perform multiple or repetitive tasks at the push of far fewer buttons.
  • Keyboard Shortcuts
    Most Windows programs support standard keyboard shortcuts for common tasks.  Below is a list of the more common ones.  For a full list see Windows Help on Keyboard Shortcuts.
