A very different question about da polisher

I have a service related brain injury that has severely limited the use of my left hand and arm. In the past couple of years it has gotten much worse. Does anyone know of a polisher that has enough power and can easily be used with one hand? Not looking for sympathy, I have been able to do most things I wanted and needed to do. One gets really good and finding ways to compensate. I was wondering if a electric da sander would work? I know it`s a very small throw though. Not sure how that would work. Looking for advice from those who know much more about this subject. I`m definitely a amateur when it comes to paint correction. Thank you for your support.
