Deadlift Stance, Measuring Hip Rotation, and Hemorrhoids – Movement Debrief Episode 102

Movement Debrief Episode 102 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 the infrasternal angle (ISA) relate to deadlift stance? Which ISA presentation are typically better deadlifters? How can I select the most effective deadlift stance What’s the difference between measuring hip rotation in sitting, prone, and supine? What are hemorrhoids? What may be a mechanical cause for hemorrhoids? What movement limitations may be present? How can I go about improving hemorrhoids?

Anteversion, Retroversion, Squat Stance, and Tissue Tolerance – Movement Debrief Episode 101

Movement Debrief Episode 101 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 does a foot turn out or in? How can we decide how much foot position is related to normal femoral torsion or ventral cavity movement limitations? How much does femoral version matter? Should we advocate for a straight foot in all activities? Why and when should we apply a straight foot position? How does this relate to running fast? What do different stance widths do to the squat? How can impingement happen in a squat? How can I find the “best” stance width on a squat? How do I explain tissue tolerance to clients? What about tissues such as joints or nerves? Do those also have tissue tolerance?

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! and the audio version…                  Here were the links I mentioned: Sign-up for the Human Matrix in Seattle, WA on September 15-16th here Sign up for the Human Matrix in Kansas City, KS on October 27-28th here   Sign-up for the Human Matrix in Portland, OR on November 10-11 here Mechanics of the respiratory muscles Action of the diaphragm on the ribcage Below is the diaphragm picture I mentioned. Notice how from this angle, the diaphragm fibers would pull the ribcage inward.     Here is a bunch of stuff on the infrasternal angle.

Knee Mechanics During the Bodyweight Squat

A Note from Zac This week we have a guest post brought to you from my boi Benjamin Fergus, a Chiropractor friend of mine, who sent me an incredibly comprehensive video on squat mechanics. I first met Ben at a DNS course way back in the day, and he was a pretty sharp kid then. Having watched this video, I can see that his knowledge base has only grown. In this spot, Ben goes over the mechanics of the bodyweight squat, and I think you folks will tremendously appreciate his explanation of what is occurring at the knee. Once you’ve finished watching the video, check his stuff out at GRIP Approach. You won’t be mistaken. Enjoy! ~Zac The Knee’s Position in the Squat This overview of the ‘Complex Movements of the Knee Complex’ is not intended to tell you the right way to squat, but rather to show what is happening with the anatomy during movement and why. It also will show you how to read/name the movements with observation from the side and front. Here on earth gravity is king in a squat. We like to keep the line of gravity and center of mass (COM/COG) situated over the midfoot. All variations of the squat can be seen as unique attempts to move our mass closer to the ground while keeping the COM over the midfoot. There are no rights or wrongs named in this video, just a look at the possibilities of joint motion. What does ‘ knee internal

Course Notes: Cantrell’s Myokin Reflections

Third Time’s a Charm Mike Cantrell was in my neighborhood to teach Myokinematic Restoration by the folks at PRI. And I couldn’t resist. This is the third time I have taken this course, a course I feel I know like the back of my hand, yet Mike gave me several clinical gems that I want to share with y’all. This post is going to be a quick one. If you want a little more depth, take a look at my previous myokin posts (See James Anderson and Jen Poulin). Or better yet, take a PRI course for cryin’ out loud. Hip Extension, We Need That Yo.  Sagittal plane is your first piece needed to create triplanar activity. Since this is a lumbopelvic course, we look at getting hip extension as high priority. If I am unable to extend my hip, here’s what I could try to use to do it: Back SI joint compression Anterior hip laxity Gastrocnemius and soleus. We use two tests to see if we have hip extension: adduction drop (modified ober’s test) and extension drop (Thomas test). The adduction drop will look at your capacity to get into the sagittal and frontal plane, and the extension drop test will look at your anterior hip ligamentous integrity. A positive extension drop is a good thing if you are in the LAIC pattern. It means you didn’t overstretch your iliofemoral and pubofemoral ligaments. Well done! The reason why this test is not a hip flexor length test has to
