Carpal tunnel syndrome
Carpal tunnel syndrome, also known as RSI (repetitive strain injury), is the swelling of small blood vessels or nerves, usually in the hands or wrists. This pressure on the nerve disrupts its function, causing numbness, pain, and a loss of manual dexterity. Treatment can vary from splinting the wrist as shown in the picture, drugs, and in severe cases, surgery.
With computers, carpal tunnel syndrome may occur as a user makes repetitive motions on an input device such as typing on their keyboard or using their mouse. Common methods of preventing this injury include purchasing a Natural Style ergonomic keyboard, taking breaks, and doing wrist exercises.
Today, an RSI is the most common job-related injuries in the United States.
