How long could one stay there and not have permanent damage, and what might it feel like after a long time? Would the spinning and rocking or 'weightlessness' have a somatic or psychological effect? (He will be blindfolded and disoriented because I'm a mean writer). I have heard having the hands suspended above the head is excruciating after a long enough time - but was not able to find out if it was the muscles or the swelling above the wrists. I have also contemplated having weight attached to the feet, but the no permanent damage rule still applies:
Pain, mental suffering, but nothing hurt that can't be fixed.
Oh- and I an guessing the wrists would be tied with rope (though I have contemplated shackles if it would make for better drama).
* I have googled Medieval hanging from pulleys, but they all have the strappado, hands in back, substantial bone and muscle damage. Ditto for this site. On Wikipedia it mentions squassation as being hands tied in front, but from everything else I've read, this is an error (and hand were still tied in back). Or do I err?
