Inverted Orthotic Technique for Severe Pronation: A Study Attempting to Document what it Actually Does

In 1981 I designed the Inverted Orthotic Technique, also called the Blake Inverted Orthosis. It is well accepted in the world for helping patients, as this study states, but what does it actually do to the running mechanics is hard. I wish I was around the design of these studies to individualize the amount of correction and the modifications necessary based on Strike patterns. But, I am happy it helps patients every day around the world.
