Dynamic neuromuscular stabilization (DNS) is a rehabilitation and movement approach that uses the movement patterns of infant development as a blueprint for how adults should stabilize their bodies. Developed by Czech physiotherapist Pavel Kolar, it starts from a simple premise: every healthy baby progresses through the same sequence of postures, from lying on their back to rolling, crawling, and standing, and those early patterns represent the ideal way the nervous system organizes movement. When adults lose access to those patterns through injury, sedentary habits, or compensations, DNS aims to retrain them.
How Infant Development Connects to Adult Movement
DNS is built on a field called developmental kinesiology, which studies the movement milestones all healthy infants pass through during their first two years of life. These milestones, rolling, propping on hands, crawling on all fours, pulling to stand, aren’t learned by watching others. They emerge from hardwired programming in the central nervous system. Every baby on earth follows roughly the same sequence, in roughly the same order, without being taught. DNS treats that sequence as a reference standard for how human movement is supposed to work.
The core idea is that these early developmental patterns establish three things in a specific order: trunk stabilization first, then limb movement, then locomotion. A baby stabilizes its torso before it can reach. It controls its spine before it can crawl. DNS applies this same hierarchy to adult rehabilitation: before you can move your arms and legs efficiently, you need to restore the deep stabilization patterns that should be running automatically in the background. When those patterns break down, the body compensates, and over time, those compensations can lead to pain and injury.
The Role of Breathing and Core Pressure
One of the central mechanisms in DNS is how you use your diaphragm. Most people think of the diaphragm as a breathing muscle, and it is. But it also plays a critical role in stabilizing your spine. When it works correctly, the diaphragm descends during inhalation and increases pressure inside your abdominal cavity. This intra-abdominal pressure acts like an internal brace that supports the spine from the front, while the deep muscles of the back support it from behind.
In many people with back pain or poor movement habits, this system doesn’t function well. The diaphragm may stay elevated, the deep abdominal muscles don’t engage evenly, or the person relies on superficial muscles (like the rectus abdominis, the “six-pack” muscle) to do a job those muscles weren’t designed for. DNS practitioners assess whether you can generate and regulate this internal pressure properly, then use specific exercises and positions to restore it. The goal isn’t just stronger abs. It’s retraining the coordination between your diaphragm, pelvic floor, and deep abdominal wall so they work together automatically during movement.
What Joint Centration Means
Another key DNS concept is joint centration: the idea that a joint functions best when it’s in its most mechanically neutral position, with balanced muscle activity on all sides. Think of a ball sitting perfectly centered in a socket versus one that’s pulled slightly forward or to one side. When a joint is centrated, forces distribute evenly and the surrounding muscles can do their jobs without overloading any single structure. When it’s not, certain tissues bear more stress than they should, which over time can cause wear, inflammation, or injury.
DNS uses developmental positions to train this balanced joint alignment under load. For example, a crawling position naturally centers the hip and shoulder joints while requiring the trunk to stabilize. By working in these positions, the nervous system relearns how to maintain centration during more complex activities like running, lifting, or throwing.
How Practitioners Assess You
A DNS assessment looks different from a typical physical therapy evaluation. Rather than testing individual muscle strength or range of motion, the practitioner evaluates how your whole stabilization system works during functional positions. A formal DNS assessment protocol includes 11 specific tests, each designed to reveal how well your nervous system coordinates stability during different challenges.
Several of these tests are done while you’re simply sitting. In the breathing stereotype test, a practitioner watches how your ribcage, abdomen, and shoulders move when you breathe. In the intra-abdominal pressure test, you sit upright while the practitioner places their fingers above your groin and asks you to push outward against them. They’re checking whether you can activate deep abdominal pressure evenly on both sides, and whether your belly button shifts or your abdominal wall bulges asymmetrically.
The diaphragm test involves the practitioner placing their fingers between your lower ribs from behind and asking you to breathe into their hands. They’re looking for lateral expansion of the lower ribcage and activation of the muscles along the sides and back of your abdominal wall, not just the front. If only the front of your abdomen expands, or if your shoulders hike up, that signals a dysfunctional pattern.
Other tests progress into more demanding positions. The hip flexion test checks whether your spine stays stable when you simply lift one leg while seated. The bear position test has you on hands and feet with knees hovering just off the ground, a position borrowed directly from infant development. The squat test evaluates your stabilization from multiple angles while you hold a 90-degree knee bend for 30 to 50 seconds. Across all these tests, the practitioner is looking for the same thing: does your deep stabilization system activate correctly, or does your body cheat with compensatory patterns?
What the Evidence Shows
Research on DNS is still growing, but the existing clinical trials show promising results, particularly for back pain. A randomized controlled trial on people with chronic lumbar disc herniation found that DNS exercises reduced pain intensity by 4.0 points on a standard pain scale, with functional disability scores dropping by 26.2 points. Both improvements were statistically significant compared to a control group. These changes reflect not just less pain but meaningful improvements in daily function, things like being able to sit longer, bend more easily, and return to normal activities.
Research has also explored DNS in neurological populations. Studies have examined its effects on diaphragm movement, postural control, balance, and walking ability in people with cerebral palsy and in patients recovering from stroke. Clinical trials are also investigating its potential for older adults with chronic nonspecific low back pain, based on the reasoning that the same developmental principles that help athletes can also help aging bodies maintain stability and reduce fall risk.
Who Uses DNS
DNS is used across a wide spectrum. On the clinical side, physical therapists and chiropractors apply it to patients with back pain, neck pain, joint problems, and post-surgical rehabilitation. On the performance side, sports therapists and strength coaches use it with elite athletes to improve force production and reduce injury risk. The logic is the same in both cases: if you restore optimal stabilization patterns, you create a more efficient foundation for whatever the body needs to do next, whether that’s picking up a grandchild or throwing a fastball.
Practitioners who specialize in DNS typically complete a multi-level certification program that progresses from foundational courses through advanced clinical applications. The training emphasizes a deep understanding of developmental kinesiology, meaning practitioners need to know the details of how infant movement unfolds month by month and how each stage relates to adult function. This makes DNS somewhat more specialized than many other rehabilitation approaches, and finding a trained practitioner may require some searching depending on your location.
What a Session Looks Like
If you go to a DNS-trained practitioner, expect a hands-on evaluation in several positions: sitting, lying on your back, on your stomach, on all fours, and standing. The practitioner will watch you breathe, move your limbs, and hold positions while they palpate your trunk muscles to feel what’s activating and what isn’t. The exercises you’re given will often look deceptively simple. You might lie on your back and practice breathing into your lower ribs. You might hold a crawling position while focusing on keeping your spine neutral. You might sit on the edge of a table and slowly lift one knee.
The difficulty isn’t in the positions themselves but in performing them with correct stabilization. Many people find that movements they assumed were easy become surprisingly challenging when they’re asked to do them without their usual compensations. Progress in DNS tends to be gradual, building from simpler developmental positions toward more complex, upright, and loaded activities over the course of weeks or months.
