Repetitive strain injury amongst IT workers and computer users
What is a Repetitive Strain Injury (RSI)?
Repetitive strain injury (RSI) represents a group of conditions associated with the overuse of computer, guitar, knife or a similar motion or tool. It is an occupational overuse syndrome affecting muscles, tendons and nerves in the arms and upper back and is also known as work related upper limb disorder (WRULD).
It is most common among computer and assembly line workers.
IT Professionals and RSI
The use of computers has increased manifold in all spheres of life including professional and personal lives of individuals. This has in turn, increased the scope of RSI to the hands and arms resulting from the overuse of the computer keyboard and mouse.
If you are a regular computer user and witness a few of the below symptoms, you could be suffering from a computer related RSI:
- Tightness, discomfort, stiffness in the hands, wrists and fingers
- Tingling or numbness in the hands
- Loss of strength and coordination in the hands
- Constant pain in the upper back, shoulders or neck
- Feeling the urge to massage your hands, wrists and arms
The disorder can actually affect multiple parts of the body, including eyes, neck, shoulders, forearms, thumbs, upper back, hands, wrists, fingers and arms.
Incidence and Prevalence
Research shows that 60% of IT professionals, who spend more than eight hours a day on the computer, are likely to suffer from the symptoms of RSI at some point.
Once contracted, such symptoms of RSI are extremely difficult to cure and can occur even in the young and physically fit individuals. In fact, people are often forced to quit their computer-dependent careers due to this disorder.
