I use a CST Laser trackball. While pricey at first, it has been bombproof over 7 years of use.
Developed RSI in dominant hand two decades ago using mouse for long sessions of dialog editing in a DAW. Moved to a Kensington which relieved one RSI but over time developed another in a different location. Moved on to Logitech and haven't had RSI issues since. This one in particular:
I use the Logitech MX Ergo. Have done so for many years.
I've just bought a ploopy diy kit. No idea how good is it just yet, but it uses quality parts and is open source.
Thinking about it, I can see how my hand-on-mouse posture, hour after hour, could affect everything from shoulder to fingertip... but actual finger-clicking strain is negligible.
I used to use a trackball and I loved it. It was the large finger ball kind. Logitech Marble FX. Obviously wouldn’t use it for gaming but I wasn’t limited in anything else
Years ago I used an Evoluent Mouse which is vertical oriented and that helped my wrist. I now switch hands for about 20% of use each day and if I think of it.
Yes, I think about the vertical mice, but I don’t have wrist issues. More like index finger strain.
Maybe you just need to meet the right mouse?
Seriously: using one that is too small could strain the finger, for instance. Having a mouse whose body comfortably accommodates the relaxed hand, requiring little or no effort click, on the other hand?
Unless you are gamer, or some other kind of manic clicker?
I've been using trackballs for many years for work (currently a logitech wireless model). I switched due to mouse-related RSI, but that mainly showed up as wrist and elbow pain. Since the trackball doesn't move that stress is completely eliminated. Not sure it would help with finger pain, as you still have buttons to click. I still use a mouse for gaming btw; trackballs suck for that purpose.
I have started regular finger stretching and that has helped. Will likely pick up a cheap wired trackball to see how it goes. Although I think I already know I will probably prefer the big ball one.
