Just jumping on this to say: I had chronic lower back and wrist pain for a long time. Had the whole ergonomic setup. Adjustable desk, Kinesis keyboard, vertical mice, etc. What fixed me was starting to squat. Took like 3 weeks of squatting and I haven't had back or wrist pain since (it's been 10+ years). Now I just use the standard (and very nonergonomic) Apple keyboard and mouse.
