Repetitive Strain Injury
This is the name given to a group of conditions that are brought on by doing repeated physical movements. In the case of computers, the repeated movements are to do with using the keyboard and mouse, and affect mainly the hands and wrists. The conditions include tendonitis and carpal tunnel syndrome. All of these problems can be serious and crippling, if they are not dealt with in the early stages of the condition.
