Ergonomics is the study of the relationship between workers and their environment especially the equipment they use.
Ergonomic design is the development of furniture and equipment which will help to relieve health related problems such as RSI.
Upper limb disorders (ULDs) affect the arms, from fingers to shoulder, and neck. They are often called repetitive strain injuries, ‘RSI’, cumulative trauma disorder or occupational overuse syndrome.
The pain in the carpal tunnel is caused by excess pressure in your wrist, which leads to inflammation. The most common cause of this inflammation is often an underlying medical condition that causes swelling in the wrist or obstructed blood flow.
Cubital tunnel syndrome is caused by increased pressure on the ulnar nerve, which passes close to surface of the skin in the area of the elbow.
To prevent :
Neck ache-have a regular rest
Backache-stretch your back when you are sitting down
Eye strain-have a regular rest
Poor blood circulation to legs-you should be able to put your feet on the floor or supporter to put your feet on
Aching wrists and fingers-have to stretch and exercise the fingers and the wrist
