Interesting. I've never been ask to do this. It may be because I tell them I am hearing impaired and that I will not be able to hear their instructions. I tell them if they want me to raise my arms, just lift them slightly, I will feel it and raise them straight out. When they want them down, I tell tell to to put a little pressure on the top and I will lower them. It eliminates vocal communication and it gets the job done. The turning over part may get too complicated for them.
