You are probably aware that there are many different types of RSI. I have used some of the following remedies for some types of RSI with some success. 1. Ulnar tunnel syndrome (numbness and tingling in the 4th and 5th finger of the mouse-using hand). All sorts of computer mice can apparently cause this due to pressure on the ulnar tunnel. Automating all mouse actions by using Autohotkey mouse macros helped very much in my case. Using a mini pen tablet (temporarily) as mouse replacement may also help to some degree. 2. Tennis elbow (painfulness of the outer part of the elbow) from too much mouse clicking. Temporary relief may be obtained by careful (!) Botox application in very small doses by an experienced (!) neurologist. Do not try this at home. This leads to a therapeutic paresis of the affected muscle and consequently to a temporary immobilization of the affected tendon that lasts several months. Please note that the abovementioned procedure will only cure the tennis elbow if the underlying cause (too many mouse clicks) is completely removed e. g. by using Autohotkey mouse macros. Please note that Botox may lead to serious harm if given by inexperienced and/or incompetent persons. Reference: Lin YC, Wu WT, Hsu YC, Han DS, Chang KV. Comparative effectiveness of botulinum toxin versus non-surgical treatments for treating lateral epicondylitis: a systematic review and meta-analysis.

I have found that using a reclining chair with an angle of at least 45 degrees backward combined with a high backrest and headrest may help to some degree.
