I am trying to find out if I am correct about the physical impact on a relatively healthy 30-something male of holding his arms up for a long while without restraints. Translate a long while to an hour or more. He is simply being forced to "keep his hands up" and not to move them (hands or arms). The penalty for lowering them is, basically, death.
I looked up "holding hands above head" "holding arms up" on Google (oddly, I got alot about pregnant women worrying about strangling the baby) and I looked at bondage sites. I did get this: "Keeping the hand(s) above the level of the heart during work or sleep can prevent appropriate blood perfusion of the hands, and cause numbness, tingling or partial paralysis of the hand(s) within few minutes."
My assumptions are that (1) the shoulders, neck, and upper back would begin to ache, then really hurt, then be agonizing, (2) shrugging the shoulders a bit might help, but not for long, (3) the arms and hands would go numb no matter how hard he tried to keep them from going numb, (4) once he was allowed to put them down it would take a while to regain sensation, and (5) even after he could feel them, his arms would be weak for a while. I don't think any permanent damage would result without restraints, but I may be wrong.
Thanks in advance for any help.
