Replying to Shoulder braces?

I rode up Emerald on Whistler last weekend with a guy who was in the stompede, he was telling me about how he has dislocated his shoulder, much like me, and he now wears a donjoy shoulder stabalizer that limits range of motion and provides support heavin forbid you fall. Wondering if anyone else on here uses/ has used one of these before, how it feels and if youve sustained an injury while wearing it? I know this is no substitute for good old physio but it might be a good pre-caution. Thanks
