It was a Long Week After an incredibly long 5 days, I finally got the chance to assimilate what I learned from the Prague folks at the C level DNS course. Despite coming out with a few good exercise tweaks, I left disappointed. I will need some extreme convincing to continue on with their course work. A man I respect a lot, Charlie Weingroff, likes asking a question regarding interventions: “Can your treatments beat my tests?” With that in mind, I looked at DNS’s capability to beat my tests, which are predominately making changes to PRI objective measures. The answer: Mostly no. I felt a lot of activity with many of the exercises, but if we cannot make measurable changes, then the intervention is not effective. And with the DNS “objective” measures, positive change is attributed visually only. I don’t care how good your eyes are, you can never know if a joint achieves maximal bony congruency by just watching movement. Granted, I did get a few things that I will use regularly. But to get 4 or 5 takeaways for a $1000 price-tag, I feel there are better ways to spend money. Like on shawarma and stuff. Here are my likes and dislikes. Days 1 & 2 aka DNS A & B The first two days were predominately review of the A and B courses; looking over developmental positions and reflex locomotion. It was nice to review old concepts, but does it really have to take two days to

Course Notes: DNS Summit
Why? In my short time out I have gotten heavily into the influence that breathing has on the nervous system. Obviously PRI has been my favorite explanation thus far, but the DNS approach had me intrigued. The summit is the first of two DNS courses that I took this past week. This summit was the first of its kind, and was an amalgamation of many different speakers. Unfortunately, this summit was mostly review and wrought with little innovation. Here are some of the big points I got from a few of the speakers. “Developmental Kinesiology: Three Levels of Motor Control in Assessment and Treatment of the Motor System” by Dr. Alena Kobesova There are three levels of development: spinal, subcortical, and cortical Spinal level of motor control is primitive reflexes; subcortical motor control is core stability; cortical motor control includes individual patterns. DNS suggests inhibiting primitive reflexes instead of facilitating them for function. Core stabilization occurs first at 4.5 months development, then locomotion follows. All movement patterns are either ipsilateral or contralateral. The former develops in supine, and the latter in prone. “DNS Among Elite Athletes – MLB” by PJ Mainville Didn’t get much out of this one except PJ dancing around PRI 🙂 Recommended using theratube around the wrist so you can perform hand movements with PNF patterns as such. “DNS in Gynecological and Obstetrics Disorders” by Martina Jezkova When in quadruped, the pelvic floor does not create a base for the trunk and had no postural function. The

Whew, I recently finished (and still trying to process) the B level DNS course from the folks at The Prague School. Instructors were Martina Jeszkova and Dr. David Jeurhing. There were a lot of things covered during this 4 day course and I definitely learned a few things. Here are the highlights. Developmental Principles The focal point of DNS is the concept of joint centration, a static and dynamic maximal joint surface approximation. When joint surfaces achieve optimal bony congruency, the muscles surrounding the joint achieve optimal activation and highest mechanical advantage. The reverse is also true. If muscles coactivate properly, then joint centration occurs. Conversely, if optimal joint centration is not achieved then muscle imbalances occur. The reverse is also true. This change becomes very problematic, as decentration at one joint effects centration at all the other joints. This may lead to decreased performance at best and at worst increased wear on joint surfaces. Take lower crossed syndrome (or open scissors if you are a DNS fan) for example. Let’s say we had a problem with our lower back. In order to cope with this trouble, we increase lumbar lordosis and decentrate the lumbar spine. See how it affects the surrounding structures. The pelvis anteriorly tilts, which affects length tension relationships to glutes, hamstrings, and hip flexors. Thoracic kyphosis increases as well, affecting the shoulder girdle and cervical muscles. Basically, play with one body region or joint position and see how it affects the others, and you can develop
