Detroit Medical Center did it again! They hosted their second PRI course: Myokinematic Restoration. Last year they hosted Postural Respiration. The class was full of "first-timers" to PRI and by the end of the weekend they seemed pretty excited to pursue this revolutionary approach to physical medicine. As we delved into human asymmetry and the Anterior Interior Chain I took a minute to call my buddy James Anderson who was teaching the same course in San Diego. Both classes had a chance to say "hi" and have a brief visit over speaker phone. That was fun! My class is going to be disappointed to learn that my group picture didn't "save". To the group I say: "I'm sorry y'all ". However, thanks to Shelly DeRuiter PT, PRC, I have some good candid photos! I cannot say enough about Shelly. She was an excellent lab assistant and her kindness and knowledge was evident throughout the weekend. Shelly lives in Holland, Michigan now and is building her stellar practice just like when she was back in Iowa. I am a Shelly DeRuiter fan! To those of you who took this Myokinematics course this weekend remember what I said at the end: PRI is here to help. We sincerely want you to succeed with this material. Good luck with your patients and together we can learn this complex material. I hope you enjoy your paradigm shift and your new journey as much as I have!

Deep in the heart of Texas! Cervical Revolution at Goddard Orthopedic and Sports Therapy. GO Sports Therapy is a beautiful facility owned by Amy Goddard, a fantastic PRC who has taken PRI concepts to a high level in The Dallas area. She, along with my good friend Stephanie Irizarry, who is also a PRC and Gail Kaiser who is Orthopedic Certified (and a marathon running beast!) took the job of hosting and made me and the entire class feel very welcome. I am so very grateful for their wonderful hospitality. The class of 30 participants included multiple PRC's and two PRT's in attendance as well: Tara Osborne PRC, Anita Panagiotis PRC, Kasey Aikin PRC, Jennifer Bullock PRC, Amy Goddard PRC, Stephanie Irizarry PRC, James Guzman PRC, Taylor Lewis PRT and Sayuri Abe-Hiraishi!! We covered the causes of two main osteopathic cranial strains known as the Left Cranial Side Bend and Right Torsion Lesions. We also discussed malocclusions and the interrelationships of both. This led us into a journey through the asymmetric human form that was so very enlightening and helped the course attendees develop a mechanism for not only management of the cervical system but also a mechanism for interdisciplinary work with their local dentists. We had three dentists in attendance with us: Peter Lecca DDS, Anh Khieu DMD and Orthodontist Yoon Chang DDS, MS. I had Dr. Chang take the podium at the end of the course and deliver a bonus lecture on orthodontics from a cranial strain restoration point of view and it was excellent. Thank you Dr. Chang and thanks to all in attendance. It was a blast!

New York City!!! Broadway musicals, Fifth Avenue, Lady Liberty and Finish Line Physical Therapy!!! I was there to teach Impingement & Instability and Michael Conlon PT saw to it that we were well taken care of. I&I is one of those classes from which many clinicians run but that was not the case since we had almost 50 professionals present on that great weekend. It was so nice to see Alicia Ferriere DPT. She is such a wonderful host who, together with the rest of the gang at Finish Line were enthusiastic attendees. I honestly look forward to seeing Alicia at certification in Lincoln, NE this December. I love the emphasis on neurology in I&I and the attendees in the course began to see that resolving various orthopedic issues must take a neurological approach. Consider that nearly all issues of impingement are really occurring by choice! Shocking eh? Want to hear more? Join me or Ron Hruska or James Anderson and buckle up for a deep dive into the rabbit hole! See you soon!!!

During my work with Elizabeth Caughey DDS in our Integrative Postural Therapy business, we have noticed a consistent finding in many of our patients.  In isolation it was interesting but when we began to juxtapose our findings with other research and with the foundational work done by James Anderson MPT, PRC we considered these findings much more important.  The following white paper is a summary of those findings. Enjoy!

After a week of respite in Sydney and the Hunter Valley wine country, I was able to start the Impingement & Instability class that began on Saturday the 3rd of June.  Our location was Full Spectrum Health Solutions.  Full Spectrum was founded by Anthony Karsay an exercise physiologist and rehabilitation specialist. Anthony was the absolute best guy and was a wonderful host to us all.  The coordinator of the course was Jason Thomson and Jason is my true friend.  This man is a clinician and a healer who has an excellent grasp of PRI concepts.  He has a following of clients who adore him and truly rely on his expertise.  Jason, I cannot thank you enough for taking care of Ilene and me during our stay and for making us feel at home and like family when we are SO far from our own families.  The class was full of excellent clinicians from all over Australia and the south Pacific including Rosalba Courtney who recently wrote a commentary to one of the research articles we at PRI like to reference (more on that later!), David Lee, an osteopath from Singapore traveled 8 hours by plane to get to Sydney for the course and wants to host one as well!   Others like Aaron Doyle from Perth will soon achieve PRC status.  Craig Ambler is planning on testing this year and he will make an excellent addition to the ranks for sure.  I&I is a complex secondary level class that challenges the mind and opens the door to the frontal plane and cutting edge thought in a way no other course does.  If you were wondering if you should register then wonder no more. It is the doorway to streamlined patient and athlete management and will really excite and challenge your thoughts on PRI.  I hope to see you soon in this course!  Thank you again Australia!!!!

It's midweek in Australia and I am spending time with my host Jason Thomson.  I will have much more to say about Jason later next week after the upcoming weekend's course of "Impingement and Instability" but right now he and Ilene Stewart (my exec assistant) and I are touring wine country in New South Wales.  Jason has taken us on a journey of rejuvenation and touches souls everywhere he goes by preaching the word of PRI.  Amazing!  We have tried a lot of different wines in the Hunter Valley and we even went to a small zoo where we petted koalas and kangaroos.  Ron, I may not want to come home!  In a few days it's I&I time where we will be doing the advanced PRI gig.  I am so blessed to have the opportunity to spread the word and be in the presence of such giants like Jason Thomson.

IFAST! Indianapolis was the location of Myokinematics where I spent this past weekend. Many people are aware of IFAST and the team of Bill Hartman, Mike Robertson, Ty Terrell, Jae Chung, Lance Goyke and Tony Giuliano. These are good guys with good hearts. This was a weekend of fun and fellowship as well as fantastic learning. Bill Hartman was a fantastic host to a large group of attendees. Many were first timers to PRI and found the course to be a paradigm shift and a "game changer" as one of them put it. I had the best time this past weekend as I got the opportunity to sit and listen to Dan Houglum MSPT, ATC/L, PRC, one of our newest instructors. Dan took the reins and led the class both days and taught them about the power of human asymmetrical movement and how to control pathological compensatory strategies. As always the class was enlightening and informative and if you are planning a foray into the world of PRI then I would suggest this "front door" of entry called Myokinematics.

This past weekend I was on the road again! Teaching Cervical Revolution and being hosted by Mike Roberts MPT and his gang at Central Mass PT. These folks are the absolute best! Jacqueline Shakar DPT, Beth Reinach MSPT, Emily Mandara DPT, Laura Kidman MSPT, Dan Everson PTA and Michael Cumen DPT were all just fantastic and made all of us feel welcome. I also want to thank Anita Furbush PT, PRC and Donna Behr DPT, PRC for being such excellent lab assistants. Donna is an excellent clinician and I relied on her and Anita a great deal. I can see why Donna's new practice is thriving. Shelly DeRuiter PT, PRC was also on hand and she is such a wonderful asset to have in a class. Shelly, it was good to see you. I had two of my previous employees from my old clinic "The Cantrell Center" Cindy Rice PTA, PRC and Jamie Jaros Lochner DPT, PRC. You two are truly skilled clinicians. All 33 attendees were on hand to learn of the powerful influence of the temporal mandibular cervical chain. This polyarticular chain of muscle has such a profound influence on the neck... and teeth have a profound influence on the TMCC. How do we know when to start a dental plan? How do we work with a dentist? How do we know which oral appliance to use? These questions, and more, are broached and the reviews of this class are good. I think Ron Hruska hit a home run with the manual and the class. Looking forward to seeing you there!

Last weekend I got to spend some time in Colorado teaching Impingement and Instability. Once again, Rebound Sports and Physical Therapy hosted PRI. These guys continue to be a beacon in Colorado, leading the way with this cutting edge science. Julie Vuxinic-Martin MSPT was the consummate host and she made us all feel right at home. My buddies Michael Locasto CSCS and Chris Schepel ATC from the Arizona Diamondbacks were on hand and represented well. There were several PRC's on hand as well: Craig Depperschmidt DPT, PRC, Joy Backstrum PT, PRC, Moon Hemeyer DPT, PRC and Lisa Kelly PT, PRC. Thanks for coming and thanks for your kind words. Lisa, thanks for the lift! This class, for those who haven't taken it, is a very different PRI exploration. We move forward beyond the standard algorithms noted in the basic courses and we explore concept-driven treatment plans that provide concrete ways to treat that next layer of difficult patients. Think management of "planes of movement" and "neurological reference centers". Everyone seems to be really glad they took the course after the two days is completed. It's a great advanced course that gives you a chance for real interaction and great back and forth dialogue and we had a blast! On a side note: Rebound in Loveland is where I taught my first Myokin solo class 11 years ago! It was so nice to return.

This past weekend I was fortunate enough to spend time in Atlanta with two very good friends teaching Postural RespirationLouise Kelly DPT, PRC and James Anderson MPT, PRC.  Wait!  What?  Me and James, together?!?!   As it happened he was in town on Saturday so we got a chance to "co-teach" with Louise who patiently ran the show (in spite of James and me!). Louise is training to be the latest instructor of this class and had a fantastic group of clinicians in front of her.  I want to personally thank Liz Billeter of Sovereign Rehab who was a great host.  She made everyone feel at home and comfortable while we were there. Many new attendees were on hand as were many returning faces.  I saw the whole crew from Austin Physical Therapy.  These folks are gurus of PRI and these guys rock with Titleist Performance Institute.   What a pleasure it was to see Samantha Red DPT leading her group from Georgialina Physical Therapy into this class.  I suspect that Samantha, my old student, will soon be a PRC if she gets her way!!  Aaron Knott and Patrick O’Shea were also on hand and these guys are really killing PRI and are soon going to wind up as PRC's as well.  Sara Patterson (soon-to-be dentist?) flew out from San Francisco to be with us and we are really watching her grow in the science.  I also enjoyed seeing Peter Lazarnick DC leading the chiropractic contingent.  This is Peter's second course and he is really enjoying the science.  I could go on and on Leigh Harris, Jeremy Stone, Polina Wilson, you guys are tops!  And Amanda Orsley PTA is one of the smartest PTA's I know!  Watch her!   Anyway, this class was special and tight!  We learned a lot about the role of the diaphragm and its influence on gait and mobility and if you are considering going to this class, I would highly recommend it!  I look forward to seeing you there!
