Ulnar Nerve Subluxations, Testing Variability, and Pelvic Tilts and Lordosis – Movement Debrief Episode 39

Movement Debrief Episode 39 is in the books. Below is a copy of the video for your viewing pleasure, and audio if you can’t stand looking at me.

Here is the set list:

  • Why would the ulnar nerve sublux or the triceps tendon snap?
  • What are the variability patterns of the elbow?
  • How to improve elbow variability to potentially reduce subluxations
  • How did I choose the variability tests that I use?
  • Why did I switch to the Active Midstance Test and Copenhagen Adduction Test?
  • How are infrasternal angle, lumbar spine, and pelvic position related?

If you want to watch these live, add me on Facebook, Instagram, or Youtube. They air every Wednesday at 7:30pm CST.

Ulnar Nerve Subluxations

Testing Variability

Pelvic Tilts and Lordosis


  1. Hey Zac

    with the AMT, I have been trying it with a guy who is quite short and round . Bottom heel lifts on both side, but he has good hip ROM in sitting. ISA is normal (was wide). What would I go after in this case? Are there cases where the bottom heel will always lift (ie. retroverted hips)


    1. Hey Marcel,

      I question how often we see true retroversion where position is controlled. Probably only saw two cases in the last 3 years.

      If they can’t keep the heel down but have good IR, then it seems there is an inability to actively IR the bottom leg. I work chase that and see what you get.

      Great question!
