The spine is the foundation isnt it? You cant stabilize properly if the T-Spine is stiff and if you cant create stabilize properly your shoulder/hips will develop issues which would cause a downstream effect wouldn’t it? My understanding is that no matter what you do to your ankle, it’ll still have issues if the hips are wacked – but if your hips are good it’ll atleast put less pressure downstream to the ankle allowing better positioning, which may not be the issue but why try to mobilize the ankle if its unable to get into a good position anyways. I’m not saying your PT is wrong, that’s just what my take on K-Star’s work is – which my interpretation could be way off.
