There was some discussion on the TBB board about chair yoga. Which brought me back to my files and I pulled up a document that I printed out last year about this subject.
The American Pain Foundation, sponsored Sosha Stuckey to create this six week course to help those with chronic pain and disability this chair yoga class. So, go on over there, take a look at the document, and if it is of to use for you, leave a comment! Thanks!
There is also a booklet: http://www.painfoundation.org/ManageYourPain/Yoga/yogabooklet.pdf
