I came her to comment on the quote from Ousterhout that, "It's not clear to me that you can ever "recover" from RSI; all you can do is stabilize at your current level of disability." I hope he got a chance to fully recover.

I too had debilitating RSI, leading to needing wrist braces and typing with a pencil lodged in my left hand and a few achy fingers on my right.

The book "It's Not Carpal Tunnel Syndrome!: RSI Theory and Therapy for Computer Professionals" [1] really opened my eyes on how to treat it.

I didn't start weight training, but did spend at least 20 minutes a day on trigger point therapy between my shoulder blades and elbow crease. That helped the most.

Then a vertical mouse, split keyboard, ergonomically placed chair, and correct table height helped prevent the recurrence.
