Ron's a genius. Thanks for sharing.

Thank you for sharing this video. The numerous different presentations of compensatory patterns is fascinating. Is there a follow up video to the two case studies? Merci

If after heal strike at toe off when the knee should bend, if you cant bent the knee and more pronation happens with the externally rotated foot, does this mean that if you have an overpronation than more than likely your not bending the knee and going through heal stroke with a straight leg. Hyper extended? Really trying to understand this. I seem to have a externally rotated right foot. Learning about ZOA also as part of this but your explanation with the picture board seems to help me understand this... I think. LOL

Is Ron of Polish origin? As drinking from a cup with the Polish national emblem on it- THE EAGLE.

Nice coffe cup ;) greetings from Poland ;)

What do you mean by pushing the floor down or up?

Do you consider the effect of small receptor on bottom of foot influence on kinematics and feeling grounded?
