It makes sense, intuitively, that standing would: (a) keep more pressure off a wound than even the best air mattresses, and (b) aid in circulation to the buttocks. I read claims of these two things, but is there any MEDICAL AUTHORITY to support them? Any studies or clinical trials, even scholarly articles?

I need the medical authority to provide both my doctor and the insurance company in order to get a standing wheelchair. Thank you in advance for any help or leads.
