Foot “core” anyone?
And a good time was had by all. Day 1 of the event in Vancouver. Lots of info and a bonus exercise session. Thanks to all who attended and looking forward to another great day tomorrow!
We spent a great deal of time talking about muscular firing sequences and the reasoning as to why things fire when.
Take a look at the picture and focus on the tib posterior, flexor digitorum longus, and flexor hallucis longus. They fire from loading response and fire through terminal stance. Up to midstance, they act eccentrically to slow pronation and after midstance, they fire concentrically to assist in supination. Note the sequence starts with the tib posterior (more proximal attachments in the foot) and ends with the flexor hallucis longus, more distal attachements (because in “ideal” gait, the hallux is the last to leave the party (or the ground, in this case)). Stability is a priority, so the central or “core” of the foot needs to fire before adding on peripheral (appendicular) muscles. Remember the foot intrinsics fire from midstance to pre swing, further stabilizing the foot “core”
