Sorry you missed the video, we only had permission to share for one week!
Below are some great takeaways from the interview!
The role of the muscles is to hold the tendons stable while it recoils energy, especially in the bi-articulate muscles for runners
Providing uniform strain through the tendon promotes steady remodeling within a tendon
Achilles Tendinosis can be related to a strain distribution problem, leading to an alteration of load in the tendon.
Specific Factors Overloading the Achilles:
Poor Rearfoot on forefoot stability *
Positive Ankle power on contact
Poor hip contribution in gait
Patients need to earn eccentrics by being able to control rearfoot while stabilizing forefoot
A great test is to watch someone doing multiple single leg heel raise and observe for a lack of rearfoot inversion at the top portion. If they fall into eversion before 20 reps they do not pass because this puts the Achilles into an elongated position
Big Toe is responsible for 80-85% of the stability of the foot
Need to build a stable Truss
Exercise Recommendations to build a good rearfoot and forefoot link
Toe Yoga (TOGA!) *tip from Jay is to make sure the arch is maintained by putting a reference object so that they are not everting the foot while moving the big toe*
Weight bearing foot supination/pronation while maintaining contact of the hallux
Mobo Board Band Twist (one I have personally found great success with!)
Foam Roller Drill: Foam roller between shins, even contact of the foot underneath met heads, adduct the legs to squeeze the foam roller, then have them IR/ER hips (alternatively keep the hips still and rotate the feet - this teaches them how to differentiate upper and lower body rotation)
