Frequently asked questions

What is RSI and how does typing cause it?

Repetitive Strain Injury (RSI) is a category of musculoskeletal condition caused by repeated movements over time. Typing involves thousands of small, repetitive finger and wrist motions daily. Over years, this accumulates stress on tendons, muscles, and nerves, potentially causing pain, numbness, and lasting damage.

How accurate is this RSI risk score?

This calculator uses ergonomic research benchmarks to produce an indicative risk score. It is not a medical diagnosis. If you are experiencing pain or discomfort, please consult a physiotherapist or occupational health professional.

How does voice typing help prevent RSI?

With voice typing you stop typing most of your text, which cuts keystrokes by up to 80%. Less repetitive hand and wrist movement means less cumulative stress on the tendons and muscles involved.

What is the safe daily typing limit?

Ergonomic guidelines suggest limiting sustained typing to under 6,000 keystrokes per hour and taking regular breaks every 45–60 minutes. The exact safe threshold varies by individual, equipment, and posture.
