If you find something about this, would you be willing to post a link in your LJ? I've apparently inherited pretty serious arthritis myself (hence the neck surgery) and would love to find alternative methods of moderating it, too.

More generally, that sucks, probably even more than being diagnosed with arthritis at 41 (which is still suckily young, but at least there's a higher first digit). I suspect you'll find some way to continue to live and thrive and be active despite it, however!
