REPETITIVE STRAIN INJURY (RSI)

WHAT IS REPETITIVE STRAIN INJURY?

Repetitive strain injury (RSI) is a term used to describe pain which is caused to muscles, nerves and tendons by repetitive movement and overuse. The condition commonly affects muscles and tendons acting over the, elbow, wrist, hands, neck and shoulders. RSI is usually associated with repetitively carrying out a particular activity over a long period of time. It often occurs in people who work with computers or carry out repetitive manual work.

TYPES OF REPETITIVE STRAIN INJURY:

There are two types of Repetitive Strain Injury:

TYPE 1 RSI:
When the injury is able to be diagnosed as a recognised medical condition, such as carpal tunnel syndrome. Symptoms usually include swelling and inflammation of the muscles or tendons.

TYPE 2 RSI:
When the injury cannot be diagnosed as any medical condition from the symptoms. This is normally because there are no obvious symptoms, other than feelings of pain. Type 2 RSI is also referred to as non-specific pain syndrome.

TYPES OF REPETITIVE STRAIN INJURY:

Below is a list of several medical conditions and injuries that can be classed as Type 1 RSI.
