You are right I am focusing on my walking my leg bent and stiff and in one session with mfr my leg is pretty straight I mean I have been working on straightening exercises at home also…..next is trying to get more bend in my knee … I know good luck with that it has been impossible …. Thank you I am sorry you still having tuff time….. Theresa
