A common form of Repetitive Strain Injury (RSI) produced by repeating the same small movements many times. As more and more people use computers, carpal tunnel syndrome and other forms of RSI have become more prevalent. Typical symptoms are numbness or burning in the fingers or wrist. If not addressed early on, the injury can cause permanent damage.
There are a number of ways to avoid carpal tunnel syndrome, including adjusting the height and angle of your chair and keyboard, and taking frequent breaks from typing. Modern office furniture, designed especially for computer use, can help considerably.
