Once again, thank you for responding. I did forget to mention that my knees do make a 'click' sound when i jump which and the fact I had poor cushioning with high arc feet. With all the symptoms mention in PFPS, in sounds pretty much like my condition. Not to mention my family does have some knee history problem.

As much as I read about PFPS on the web, I hardly come across the with 'Spinal Protective Behavior'. I remember my physio said something about nerves but never went deeply into it. I'm quite interested to know more about it and more about the treatment of Continuous Mobilization. I currently live in Sydney, if you do know someone who specializes in it, let me know.

Thanks ginger
