Course Notes: Cantrell’s Impingement and Instability, 2015 Edition

Third Time’s a Charm  A trip home and hearing Mike Cantrell preach the good PRI word? I was sold. Impingement and Instability is one of those courses that I could take yearly and still get so many gems. In fact, I probably will end up taking it yearly—it’s that good. I took I&I last year with Cantrell (and the year before that with James), and the IFAST rendition was a completely different course. Cantrell provided the most PRI clinical applications I have seen at any course, which is why he continues to be one of my favorite people to learn from. Basically, if you haven’t learned from Mike yet, I pity you. Get to it! I have way too many gems in my notes to discuss, so here are a few big takeaways.

Course Notes: PRI Cervical Revolution REMIX

Note: I made some errors on the first rendition of this blog that were corrected after speaking with Eric Oetter. Courtesy to him, Lori Thomsen, and Ron Hruska for cleaning up some concepts. Four Months Later When the Lori Thomsen says to come to Cervical Revolution, you kinda have to listen. I was slightly hesitant to attend since I had taken this course back in January. I mean, it was only the 3rd course rendition. How much could have changed?   Holy schnikes! It is simply amazing what four months of polishing can do. It was as though I attended a completely different course. Did I get it all figured out? No. But the clarity gained this weekend left me feeling a lot better about this very complex material. This is a course that will only continue to get better with time; if you have a chance to attend please do. Let’s now have a moment of clarity.   Biomechanics 101 The craniocervical region is the most mobile section of the vertebral column. This mobility allows regional sensorimotor receptors to provide the brain accurate information on occipital position and movement. The neck moves with particular biomechanics. Fryette’s laws suggest that the cervical spine produces ipsilateral spinal coupling in rotation and sidebending. The OA joint, on the other hand, couples contralaterally. C2 is the regulator of cervical spine motion; much like the first rib regulates rib cage movement. C2 is also important for the mandible, as it balances the cervical spine during

Course Notes: Pelvis Restoration Reflections

Pelvises Were Restored It was another great PRI weekend and I was fortunate enough to host the hilarious Lori Thomsen to teach her baby, Pelvis Restoration. Lori is a very good friend of mine, and we happened to have two of our mentees at the course as well. Needless to say it was a fun family get-together. Lori was absolutely on fire this weekend clearing up concepts for me and she aptly applied the PRI principles on multiple levels. She has a very systematic approach to the course, and is a great person to learn from, especially if you are a PRI noob. Here were some of the big concepts I shall reflect on. If you want the entire course lowdown, read the first time I took the course here.  Extension = Closing Multiple Systems  This right here is for you nerve heads. It turns out the pelvis is an incredibly neurologically rich area. What happens if a drive my pelvis into a position of extension for a prolonged period of time? I’ve written a lot about how Shacklock teaches closing and opening dysfunctions with the nervous system. An extended position here over time would increase tension brought along the pelvic nerves. Increased tension = decreased bloodflow = sensitivity. We can’t just limit it to nerves however, the same would occur in the vasculature and lymphatic system. We get stagnation of many vessels. Perhaps we need to think of extension as system closure; a system closing problem. Flexion will be

Course Notes: PRI Cervical Revolution

Where are all the People? I recently made the trek to Vermont for the first rendition of PRI’s Cervical Revolution course; a course in which the attendees doubled the population of the entire state. It was nice to go to the class with a bunch of old friends. You always learn better that way, and I couldn’t have been more excited to get the band back together. And even more so, I got to meet a lot of good folks for the first time. It was a real treat. This course was meant to update the former craniocervical mandibular restoration course (which I reviewed here and here), with extra emphasis on the cervical spine and OA joint. In this blog however, I will not touch much on the cervical spine positioning. I still have several questions regarding the mechanics. Some spots within the manual seemed to be conflicting; the blessing and curse of a first run-through. I will update this piece once I get these points figured out. That said, the revolution helped fine tune the dental integration process for me. I have been working a bit with a dentist, and I have a bit more insight in terms of what devices they are using for whom. Let’s go through my big a-ha moments. Smudging 901 The human body is symmetrically asymmetrical. When we have capacity to alternate and reciprocate, we are able to separate the body into parts to form a whole. If you lack integration, then there are

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
