I would suggest trying to dissuade her. Power or not almost everything in a wood working shop is a potential finger amputator.
On the other hand, my church has a member who has serious Parkinsons, we have to help him move around. But, he is a wood worker. Our church is small and lacked a steeple. One day I drove by and saw him on the roof installing a nice steeple he had made. Scared the 'h' out of me better and our preacher ever did.
And, we have a friend who was forced to retire from being a surgeon because of a parkinson-like condition. While visiting he bought an antique item and wanted to turn a handle for it. I offered to do it but he wanted to himself. He sketched his handle, I gave him basic instructions on the lathe and, with great trepidation, let him start turning. As soon as he began all the shaking stopped and he turned a beautiful handle. He had never used a lathe before. I could see his concentration and the use of his hands clearly showed the inate skill of a surgeon.
