What is Repetitive Strain Injury or RSI?
Repetitive Strain Injury or RSI is possibly the No 1 cause of industrial injuries for office workers.
“RSI” is a catch-all phrase or syndrome for work related Muscular Skeletal Disorders (MSD). This incorporates several discrete conditions associated with activity-related arm pain such as tendinitis, carpal tunnel syndrome, tenosynovitis, golfer’s elbow (medial epicondylitis) and tennis elbow (lateral epicondylitis).
