I have had bad cubital tunnel in the past, enough so that I was learning to become ambidextrous to stop using my left hand. A surgery helped tremendously in my case, but I’m still prone to flare ups if I overuse my pinky.

An Ergodox EZ has been a lifesaver, I’ve reprogrammed it so I don’t need to use my left pinky anything other than letter keys (goodbye left shift, you’ve pained me for too long). I fully agree with the articles advice; pair a good programmable keyboard with physical activity to keep the hands working long term.

Be warned though: the more customized your keyboard the harder it is type when using a laptop or friends keyboard.
