I normally use uDivine Massage Chair for relaxation though I personally dont suffer from any chronic pain but I can easily see it being highly therapeutic for any muscle injuries- it is a serious piece of kit. From head to toe your body will be massaged back to life, restoring your energy, balance and well being. The good quality built in speakers is a nice feature - there is nothing better than relaxing to your favorite radio program while having your whole body massaged.
