I think that might be the wrong question. Mainly because we don't know how Parkinsons is affecting the person in question. For example, if only their hands/arms are affected, some kind of head controlled device would work. That would be a very specific device though, the kind that is only available through a Medical Rehab or Medical Devices company. A modified IR Tracking device or perhaps a Voice Controlled device.

Maybe a trackball. They could nudge it til it's on target rather than sending the cursor to the other side of the screen as with a mouse.

i suggest circumventing the issue and getting a huge mousemat and any mouse, and then using very low mouse sensitivity.

You could probably try finding a heavier/weight adjustable mouse. I think there are weighted utensils used to help patients with parkinson's, so maybe a heavier mouse could help.

It probably depends on how severe the condition is though.
