It's the same problem. But with different prosthetic polymers, subreplacements for flesh. If you don't know what you're doing you can deactivate all sensitivity in a limb. I'm lucky I know even basics for the outside fo the feet; that's only because they're what I damage the most, and most of what I know ends in "don't touch that," courtesy of the Doc who takes care of me. He's the only guy I trust to really know what he's doing.
