I had the pleasure of visiting Athlete’s Performance Institute in Phoenix, AZ and attending Dynamic Neuromuscular Stabilization recently.
I won’t even try to fully capture the full scope of DNS in this blog. The system, developed by Dr. Pavel Kolar, is based in developmental neurology and applies the principles of turning and creeping into assessment of the core (integrated spine stabilization system) and phasic movement of the extremities. Understanding the anticipated movements of these inborn patterns allows us to perform resisted exercise or reflex locomotion to refresh these subcortical patterns to the standard operating procedures of cortical movement. For those versed in the traditional chiropractic model of treating the nervous system and the innate, you have not seen more evaluation and influence of the nervous system or innate abilities than you will find in DNS. This technique may very well be the bridge from the beginnings of our understanding to some of the contemporary developments and methods.
For those who wish to know more about DNS, follow this link.
A few key points:
- Joint centration is essential and non-negotiable.
-positions can be modified as needed, but joint centration must remain.
- decentration of one joint will undoubtedly lead to decentration of another joint. (An undesirable chain reaction.) - What is centration? Centration is the position of maximal joint contact. This allows the most even distribution of forces through the joint as well as balanced muscular coactivation around the joint.
- Why do we want centration? Maximal motor control and power with minimal load/stress.
- Breathing and abdominal bracing (spine stabilization) are intimately related and are interdependent. Both must be maintained or the integrated spine stabilization system is compromised and stability is lost.
- Evaluate and train in multiple positions/patterns. The ‘key link’ Janda described will be evident in multiple evaluations. Retraining this key link will require repetition and myelinization through training in multiple positions.
- Newborns begin with primitive, reflexive patterns. With afferent input (stimulation) there are genetically preprogrammed movement patterns that develop at specific neurologic ages. Failure of proper neurologic development indicates a ‘central coordination disorder’ that may be indicative of CNS pathology.
- “Form follows function”: failure to follow typical developmental movement patterns can have morphologic consequences. (ex. flat foot, acetabular angle, pelvic tilt, kyphosis, etc) Louis Sullivan coined this phrase in the world of architecture, but it clearly has its place and value in human development as well.
- Zones of support during developmental positions create areas of dense proprioception. These areas can be used for stimulation during isometric exercise and reflex locomotion.
- Tactile and/or verbal cuing is used when altered motor patterns are seen. When verbal or tactile cuing is not sufficient to improve faulty patterns, then reflex stimulation may be necessary.
- During reflex locomotion there is a vector to follow, often towards the point of support (punctum fixum) or the next joint in a phasic limb. The vector is not a specific direction, but within a general region from the stimulation point. The exact vector is within a ‘cone shape’ and is determined by the clinician based on anticipatory reaction generated from stimulation.
There is a broad application of the principles of DNS as they are based on universal principles of inborn, preprogrammed movement patterns. Applications range from evaluating and treating developmentally challenged babies, to restoration of normal movement patterns in painful or restricted adults, to allowing maximal motor control and muscle activation in elite athletes. I should also mention that maximum distribution of joint forces is also applicable to all ages and situations as it will ensure proper development and maturation, help prevent future injury and joint pathology, and prolong athletic careers. This diverse applicability makes this system a valuable tool.
For their help in learning part B of the principles of DNS, many thanks to the folks at API (Darcy Norman, particularly as he helped out the B group), Ken Crenshaw & the AZ Diamondbacks organization, the Prague School instructors and Pavel Kolar, Clare Frank who instructed the B group, and course organizer Craig Liebenson.
The question that remains for me is, where is the line between good enough and not good enough? With DNS functional testing there is almost always something wrong with the pattern. From little flaws in stabilizer activation to completely inadequate coordination of breathing and bracing. What do we attack and what do we leave alone? In FMS we talk about fixing 0s and turning 1s and asymmetries into 2s and symmetrical patterns. This is easy to follow. Valdimir Janda talked about fixing the ‘key’ link, but not getting bogged down in trying to teach perfect movement. I’ve yet to find where this line is for DNS. The line may be clear in the case of the elite athlete, we want everything to be as perfect as possible to give them the competitive edge. However, for the average patient or average athlete, when do we call it ‘good enough’ vs. continuing the quest for perfect patterns. For now I’ll try to let the clinical audit process sort it out (I’m curious to hear others opinions on this question, and if I ever come up with a more concrete answer I will be sure to post it.)

I recently had two unrelated experiences that after reflection (and viewing a funny video while talking about the second experience with some colleagues) seem to have some commonality.
The fact that this was important to our guide should have been a clue about how impressive a honey badger was, but the significance didn’t set in until about an hour later. As we were stopped now viewing two adult male lions, someone remarked how fearsome the lions looked. Our guide, Wilson, explained that he was not afraid of the lions (they are often lazy and poor hunters, although good killers of the wounded or careless prey). He went on to say that he most fears the leopard and cape buffalo, but that the honey badger was the ‘toughest’ animal in the entire park. Seeing the size and complete lack of intimidating appearance of the honey badger his statement struck me as odd. Learning more about the honey badger you see that they are extremely driven, tough, and goal-oriented, but reckless in their pursuits. Thankfully honey badgers are as resilient as they are reckless.


Imagine playing soccer on a field atop a hill. Now let’s imagine that the field shrinks to the size of a basketball court, or indoor soccer pitch if you prefer, or perhaps even smaller. Imagine the challenge of keeping the ball on top of the field and keeping the game going. In FM we are thinking of balancing forward movement (an) with backward movement (re) as well as lateral movement (la) with medial movement (me). The same is true in the oblique directions (ir, ex). If we balance our movements with each plane, like kicking the soccer ball around our small field, it will remain atop the hill and we can continue to play and enjoy our game. When the balance is disrupted, for example too many kicks to one side, the game stops as the ball rolls down the hill. The stoppage of our game would be similar to crossing a tissues failure tolerance or suffering an injury. With FM treatment we can restore balance and get the ball back into the middle of the field, but what prevents this from occurring again? (Remember we’re playing on a small field.) Teaching movement pattern training would be analogous to teaching the players of this soccer game better ball control (they are less likely to have uncontrolled forces or unexpected vectors on their kicks) and the ball will likely stay atop the hill. Therapeutic exercise (such as stability training or eccentric loading) can increase the failure tolerance of tissues, this would be analogous to taking our small field and expanding it back to the dimensions of a standard field (allowing more margin for error and greater forces within the game). By doing either of these we increase the likelihood that the game continues. To review my obscure analogy, the goal of FM is to balance tissue tension, like trying to keep our ball in the center of the field. This technique is well-developed, with emerging research, and clinically applicable concepts. However, trying to keep our ball in the center of the field, without giving significant consideration to training ball control, and ignoring the fact that the field size could be increased, creates a situation where recurrence/reinjury is more likely.
