I think you have to buy the articles... they're for sale on the website http://www.yogatherapycenter.org/boutique.html as "Yoga Therapy for Knees & Shoulders".
I'm doubting about ordering it... I have no PayPal and international shipping's quite expensive :-(.
I actually hope all I need to cure my knock knees will be in the book "Structural Yoga Therapy". I'm wondering whether I'll be able to do the exercizes as a beginner, and get effects. I really hope so. I AM really motivated and ready to practise a lot! Anything (except surgery) to get straighter legs!
