I use an eye-tracker to move the mouse, voice command and a set of 3 pedals: one to toggle the eye-tracking, another to toggle voice command and third for mouse left click. I started using these during a rough patch of RSI but now that I'm recovered still used them because they prevent any of these type of issues happening again and also, they're super comfy to work with (half of my workflow is automated using voice command and moving the pointer with your eyes is essential once you've learn how to use it properly). Highly encourage to try them :D
