Foot Function and Fascial Lines Webinar

Emily Splichal put out a very nice webinar about the foot function and fascia as it deals with the first ray.
Here is the link off Facebook.  I think it will take a few days to put into the EBFT archive folder.
Foot Funciton and Fascial Lines. Part 1  Foot Function and Fascial Lines.  Part 2.

Most fascial lines cross the bottom of the foot.
Deep Front Line:  (main ones)  Tib posterior, adductors, pelvic floor and psoas.  This is how the foot interacts with the core.
Post Tib.  Attaches to a lot of stuff!  Navicular, 9 other osseous structures.  All the metatarsals but the first ray. All the tarsal bones but the talus.  Peroneus longus tendon and flexor hallucis brevis muscle.

Spiral Line: Rhomboid and Serratus, oblique muscles, tibialis anterior and peroneus longus.
Ant. Tib:  90% of on medial cuneiform, 10% on base of first metatarsal.
Peroneus Longus:  10% on medial cuneiform, 90% on base of the first metatarsal.
This is significant for 1st ray biomechanics.

Intrinsic muscles adductor hallucis and abductor hallucis control transverse plane stability.

1st MPJ Dorsiflexion:
Flexor Hallucis Longus (Deep Front Line) :  Holds the distal hallux to the ground.
Flexor Hallucis Brevis (Indirect Deep):  Pulls sesamoids proximally.
Abductor Hallucis:  Maintains 1st MPJ in transverse plane.
Plantar fascia (Superficial Back Line)  Stabilizes 1st MPJ.
Peroneus Longus (Spiral Line) Maintains 1st ray MPJ in sagital plane.

Is the spiral line balance:  Tib Anterior vs Peroneus Longus tension and strength.

How to enhance?
Stability > Mobility
Intrinsics > Extrinsics
Deep Line>Spiral Line

Practice the short foot.  (tons of info out there if you don't know what short foot is )

If you have great ROM laying down in the big toe, but when you put weight on the foot and it all goes away, check the peroneus longus.
