I know this isn't what you're looking for, but I have excellent recommendations for people with RSI and / or Carpal Tunnel.
For a while, I daily-drove a Logitech MX vertical mouse and that was wonderful. It's responsive, comfortable and really accurate, and helped my RSI in my mouse hand.
Eventually, the RSI started hurting my other wrist (my job has a really sucky keyboard) so I moved on to the Kensington Slimblade trackball mouse. That mouse is KILLER for reducing and / or eliminating RSI. It's perfect for me, because I was able to switch my main mouse hand with little issue and I've been switching them up occasionally ever since depending on which wrist hurts worse. It's not a forever solution, but it's an excellent temporary one. I really can't say enough good about the Kensington (that being said, you aren't gonna be able to game on it hahaha)
Pretty much - or Samsung, Xiaomi, Nothing or any of the other Android brands
