I know of Dr. Kahn, she is in Montreal Canada one of her specialties is PTS, I will try and get in touch with her. I did look on CJMA and could not find the study they mentioned on the "news.oneindia.in" link.
I do agree that exercises does help with fighting PTS, I have been doing a lot of biking this past summer and that is the best my (DVT) leg has felt since being diagnosed, three years ago...
