Office Ergonomics

Ergonomics is about ensuring a good fit between people and their workplace.

Due to the use of computers in both the workplace and in the home, tens of millions of users are suffering from work based injuries aka RSI or Repetitive Strain Injuries. As a result, many devices have been produced in order to make the workstation a more comfortable place i.e. chairs, foot stools, wrist rests, supports etc. The majority of computer users do find these a help.

Due to the prolonged periods of time sitting in one position the following occurs: the muscles and tendons of the hands, arms, and neck and back weaken as a result of the repeated stress throughout the day. These stresses then produce swelling of the involved joint which in turn produces pain (see also Mechanical Joint Dysfunction).

Computer users should not ignore hand pain, wrist or forearm pain, numbness (day or more commonly when sleeping) and burning or tingling sensations which can start in the hands and work its way to the neck and shoulders. The above symptoms can be a start to RSI and it is advisable that the sufferer seeks attention- prevention is the key.

Helpful hints to improve your work environment and to reduce the prevalence of RSI injuries:
