This is so fascinating! As someone who has "flat feet", I've been focusing on improving ankle dorsiflexion. It never occurred to me that my dorsiflexion may be limited to the other bony structures in front of the joint. I do feel a pinch in closing dorsiflexion which tells me that the other components of my feet are not behaving like they should. Brilliant clip! Thank you so much for this information!
When the foot is fixed to the ground in a closed kinetic chain position such as is demonstrated in the video, doesn’t the talus reciprocally glide posteriorly in relation to the anterior glide of the tibia during CKC dorsiflexion? I’m having trouble seeing how the talus would butt up against the navicular in this scenario, especially if the navicular “drops” into a plantar glide with conjunct internal rotation, further moving it away from the posterior gliding talus during the lunge or squat. If the midfoot does in fact move into pronation with subtalar eversion, I can’t see how the talus hits the navicular. Any clarification there?
My understanding is that the "pinch" referenced in the video isn't the Talus and Navicular butting into each other, but rather the Tibia butting into the Talus. If the Talonavicular joint doen't rotate, the Talus cant glide and therefore the Tibia bumps into the Talus.
Agreed. My view is the opposite. Lack of posterior talar glide in ckc will drop the navicular I.e. the forces will drive this. In clinic, we see a lack of dorsiflexion due to a lack of talar glide causing a compensation of dropped medial arch. Improvemnet in talar mechanics will reduce the impingement and compensaroty arch collapse. Unfortunaely, the support to the arch is unable to support in chronic cases.

This is brilliant! Thank you for the amazing content.
Absolute gold. I'm sad my FRA had to get rescheduled due to Covid, but looking forward to when I can see this stuff in person.
1:33 how does one do this (re-establish rotation of the midfoot)?
Pure gold, thanks
blown away. Thanks

Yes absolute valid questions..i also dont see hows that happening..

This is pure gold, thank you
how to apply this content to immobile foot? would love to discuss
Haha. The audience can’t see!
mmmm k?
This is brilliant! Thank you for the amazing content.
