Hi, I have found yoga to be very helpful for my RSI.

Modifications I've used include supporting myself on the front of the fist instead of a flat hand on the floor (e.g. for plank) and of course backing off and doing an alternative pose if it feels like I'm hurting anything.

The PT who helped me a few years ago really emphasized how important it is to gently build up my overall upper-body strength (upper back, shoulders), and I find I have fewer episodes of inflammation when I follow that advice. YMMV; namaste!

I do use Wrist Assured Fitness Gloves and it does help my wrists. I have mild-carpal tunnel in my right hand and tendinitis in my left hand. It hurt so bad I had to modify my poses. I rolled up the top of the mat in Downward Facing Dog. But that still wasn't working well. Now with Wrist Assured Fitness Gloves on helps to cushion and support my hands during Dog pose. I tell all my students who have wrist problems to get those Wrist Assured Fitness Gloves.

I bought these gloves almost a year ago and they are a godsend! I don't have it as bad as full carpel tunnel, but I was getting a lot of wrist and arm / shoulder pain. Many of my fellow practitioners at our studio, www.yogapura.com have also bought them with much success!

They have a 30 day trial - and even though they are kind of expensive, they are worth it!

thanks - jai bhagwan
