Beyond Eccentrics for Achilles with Jay Dicharry

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:

  1. Limited Dorsiflexion

  2. Poor Rearfoot on forefoot stability *

  3. Positive Ankle power on contact

  4. 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
