Ribcage Dimensions, Gait, Foot Arch – Movement Debrief Episode 56

Movement Debrief Episode 56 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:

  • How does rib external and internal rotation relate to infrasternal angle?
  • Why does the infrasternal angle measures present as they do?
  • What are the anteroposterior and medial-lateral dimensions of the ribcage in these infrasternal angles?
  • What are the thoracoabdominal pelvic cavity mechanics in gait?
  • How does a collapsed arch impact movement variability?
  • How do we treat a collapsed arch?
  • Are custom orthotics a worthy solution?

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

Enjoy!

Below is the diaphragm picture I mentioned. Notice how from this angle, the diaphragm fibers would pull the ribcage inward.
