This book provides a good overview of various treatments available to sufferers of RSI and advice on how to change your lifestyle to improve your recovery. It’s UK-centric, so it advises in terms of the NHS, which is useful. I worried that it might be rather dated, but apart from the chapter on computer software (good for a chuckle), the advice seems timeless.
What is limited is its information on useful stretches. There’s a very short list, poorly described, with stick-figure illustrations (which are close to useless). So read this book as a starting point for learning more about RSI, not as a complete guide to recovery. I’ve also picked up a book of stretches/exercises, called ‘Conquering Carpal Tunnel Syndrome’, which seems more helpful in that respect.
