  1. Hi Zac,

    I just discovered your website today via an IPA google group that mentions it. I love it! I look forward to digesting more of it. I am also planning to sit for PRI certification this winter and was actually at the same Craniomandibular course with you in Pitman, NJ a couple of weeks ago. Were you sitting in the front right (Ron’s left)?

    I started with PRI this past fall and can’t get enough of it. I am a big David Butler/Sensitive Nervous System/Explain Pain fan too. I am also a bit of a nutrition geek and have strong opinions on how the gut and immune system influence pain. I would be interested in your food notes page when you get to it but it looks like you have a lot on your plate at the moment.

    I am strongly considering doing the PRI vision course in April as well. If I do, let’s try to meet up and chat.

    1. Hey Heather,

      I most certainly was there in that spot. Pity we did not meet then, but I look forward to hanging at vision 🙂 Let’s make it happen.


  2. ok so in a nutshell a left aic/bc pattern shifts ur diaphragm and lumbar spine to the right and the ribs above the diaphragm to the left. Or is it vice versa?? Im right handed and really right dominant. When i box , to fix a left aic/bc pattern would it be better to use a orthodox or southpaw stance, Regardless of traditional rule that stronger hand should be behind.

    1. Hey Stevyn,

      Lumbar spine orients right, right diaphragm is is relaxed, left diaphragm contracted. Ribs ER on left, IR on right which creates thoracic rotation to the left in the LAIC/RBC pattern.

      The LAIC/RBC is not a problem to be fixed. It’s one-half of the gait cycle. It’s hard to say what can be done to increase movement variability without an evaluation, so I cannot say if changing a boxing stance would help with that. Depends on the individual.

      Thank you for your comment,


  3. Hello Zac,
    I just found your site. What a great idea and it looks like a great resource for those of us who can’t take in all those courses. I want to better understand PRI. Which notes should I read first?

  4. Hello Zac, I just found your site. What a great idea and resource. I would like to understand PRI better. What notes are the best to read first? Thanks.

    1. Thank you for the kind words and readership.

      Here’s the route I would go:

      myokin –> postural respiration –> pelvis –> impingement and Instability –> craniocervical mandibular –> cervical revolution –> advanced integration –> PRI vision



  5. Thanks, Zac.

    Since your reply I’ve read and re-read the 3 myokin class notes and watched many videos, yours and others. Clearly we are anatomically asymmetrical but I find that the presumption that this creates a standing posture of weight bearing on the right leg with internal rotation and adduction and on the left external rotation and abduction to be unverified in my observations. Now of course we will all be in this posture at times but I find it no more common then its opposite or equal weight bearing or any other standing posture. I base this observation on my participation in a PT lab class this weekend where about 60 individuals, mostly females, ages mid twenty’s to sixty’s all stood around watching demonstrations. I observed their postures all day. I am considering taking the PRI course in the spring, but if this basic presumption is mistaken is reduces my confidence in the value of taking it. What is your experience with this?

    1. Hey Arthur,

      I appreciate your deep studying.

      PRI is not making assumptions based on standing posture alone. You would really tease out the information with objective testing (e.g. hip rotation, “obers” test, etc). That is where you will more likely find commonalities.



  6. hey Zac,

    I came across your site via the DNM site. I really enjoy your course notes, very detailed. Also cool to see how you share you book notes. In all great site you have here.

    I am currently a massage student and am in the process of becoming DNS exercise certified and am curious as to how DNS compares to PRI. In your eyes, as someone with experience in both modalities, do you think I will be chill using just the DNS principles in the rehabilitation of pastural dysfunction? Would you recommend supplementing my DNS education with some PRI stuff solely out of their specificity in certain areas such as their thoracic scapula integration?

    any help in this matter would be greatly appreciated 🙂

    1. Hey Michael,

      I appreciate your kind words and reaching out.

      Personal opinion, I think PRI is leagues ahead of DNS. Better testing methodology, biomechanical basis, and clinically has been much more effective for me. No comparison, though not a cure-all.

      Hope this helps,
