Repetitive strain injury (RSI) - Causes of repetitive strain injury (RSI)

Repetitive strain injury (RSI) is related to the overuse of muscles and tendons in the upper body, especially the hands, wrists, forearms, elbows, shoulders, back or neck.

Things that can put you at risk of RSI include:

• repetitive activities
• doing a high-intensity activity for a long time without rest
• poor posture or activities that require you to work in an awkward position

Cold temperatures and vibrating equipment are also thought to increase the risk of getting RSI and can make the symptoms worse. Stress can also be a contributing factor.

RSI is most commonly caused by a repeated action carried out on a daily basis. A variety of jobs can lead to RSI, such as working at an assembly line, at a supermarket checkout or typing at a computer.

It is important that your working environment, for example your desk space, is laid out so that you can work comfortably. Your employer is under a legal duty to try to prevent work-related RSI and ensure that anyone who already has the condition does not get any worse.
