RSI Prevention for Typists

What Is Typing RSI?

Repetitive strain injury in typists typically manifests as pain, numbness, or weakness in the fingers, wrists, forearms, or shoulders. Common diagnoses include carpal tunnel syndrome, tendinitis, and cubital tunnel syndrome. Symptoms develop gradually and are far easier to prevent than treat. If you're switching to touch typing or building speed, pacing yourself reduces risk significantly.

Wrist Position

Your wrists should be flat or slightly negative (angled downward from hand to elbow) while typing — not bent upward. Keyboards with high back tilt force wrist extension, the main RSI culprit. A keyboard tray below desk height, a flat keyboard, or a split ergonomic keyboard all support neutral positioning. Some typists find that switching to Colemak from QWERTY reduces wrist load through reduced finger travel, though the benefit is modest.

Take Regular Breaks

Every 20–25 minutes of continuous typing, take 2–3 minutes away from the keyboard. Set a timer. During breaks, avoid your phone — that is still repetitive finger movement. If you're using the typing test to build speed, limit long endurance tests to once per day until your hands adapt.

Stretching Routine

• Wrist circles: Rotate both wrists 10 times in each direction.
• Finger extension: Spread fingers wide and hold 5 seconds, then make a fist. Repeat 10 times.
• Forearm stretch: Extend one arm, press fingers back gently with the other hand. Hold 30 seconds per side.
• Shoulder rolls: 10 forward, 10 backward. Typing pain often originates in the shoulders, not the hands.

Keyboard Choice

A mechanical keyboard with lighter linear switches (40–45g actuation force) reduces the force required per keystroke. Over millions of daily keystrokes, lighter switches meaningfully reduce cumulative load. Ergonomic split keyboards that allow wrists to stay in a natural position are another effective option for heavy typists.

Early Warning Signs

Treat tingling, numbness, or persistent aching in hands or forearms as early warning signs, not normal tiredness. Reduce intensity and consult a physiotherapist early. RSI caught at this stage typically resolves within weeks; ignored, it can become chronic.

Practice With Less Strain

If you're working on technique while managing RSI symptoms, prioritise form over speed. The home row practice lesson uses only the central row — less reach, less tension. The accuracy drills keep pace low and focus on clean movements. The weak keys guide isolates specific characters so you aren't retyping full passages to target one problem area. All of these are low-intensity compared to full timed tests.
