Carpal tunnel syndrome
Carpal tunnel syndrome, which is also known as RSI or repetitive strain injury, is the swelling of small blood vessels, 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 does repetitive motions on their keyboard or mouse. Common methods of preventing this injury include purchasing a Natural Style ergonomic keyboard, taking breaks, and doing wrist exercises.
