Interesting video here, a Rheumy in America is seen wearing a special suit that tightens his joints and restricts his movements to emulate that of a patient with RA. Whilst he obviously doesn't experience the pain , it does give him a better understanding of how difficult everyday life is and he says will change the way he treats his patients in future. (Would be handy for disbelieving work colleagues too!)
Sorry but I don't think the video will work properly on mobiles or tablets. Try to watch it on a pc if you can though, it is very interesting.
All the best
