I was never clamped down and I believe it's mostly just the head is made immobile to keep it steady. It isn't bad at all. Maybe if the imagination leads the way, it could be. Just let them do their thing as they do these every day.

Since posting this. UPMC, Pittsburgh, Oct 2011 until Jan. I averaged about 2 to 3 surgeries a week there. w Can't have jaw made as bone is deteroriating steaily that is left in jaw. Mersa is to blame. Feeding tube . Had trach for 4mos. Got it out April.
