Repetitive Strain Injury (RSI) is one of the most common and preventable occupational health problems in the world. For anyone who types for more than a few hours per day, understanding RSI — and how to prevent it — is not optional. It is a matter of long-term health and career sustainability.
What Is RSI?
Repetitive Strain Injury (RSI) is an umbrella term for pain and damage caused by repetitive movements, particularly affecting the hands, wrists, forearms, and shoulders. The most common RSI conditions for keyboard users are:
- Carpal Tunnel Syndrome: Compression of the median nerve in the wrist, causing numbness, tingling, and weakness.
- Tendinitis: Inflammation of tendons, usually felt as aching pain in the forearm or wrist.
- De Quervain's Tenosynovitis: Inflammation of tendons on the thumb side of the wrist.
- Cubital Tunnel Syndrome: Pressure on the ulnar nerve at the elbow.
- Thoracic Outlet Syndrome: Compression of nerves in the neck/shoulder region.
Primary Prevention Strategies
- Correct wrist position: Wrists neutral (not flexed up or down) during typing; hover above keyboard, don't rest while actively typing.
- Regular breaks: Follow the 20-20-20-20 rule; take micro-breaks every 20 minutes.
- Proper typing technique: Touch typing with all ten fingers reduces the load on any single finger or wrist position.
- Correct posture: Elbows at 90°, screen at eye level, feet flat on the floor.
- Stretching routine: Perform regular wrist, finger, and forearm stretches before and after typing sessions.
- Ergonomic equipment: Use wrist rests, ergonomic keyboards, and adjustable desks where needed.
✅ Technique First
The best RSI prevention is correct typing technique from the start. Use the hand animation feature in the Keyboard Simulator to verify your finger placement and movement patterns before bad habits lead to injury.
