It is difficult to believe that making such simple movements can bring about substantial improvements in bodily coordination, or release mus

We continue our series of posts exploring the semi-supine position. Here, we begin to experiment with simple movements. Developmentally primitive positions allow us to create a living laboratory, where we can observe our habitual motor behaviors under highly controlled circumstances. Turning Your Head Once you have spent time in the semi-supine position, try rotating your head. Because we habitually stiffen and shorten the muscles of the neck, it is critical to explore this m

The spine as a whole lengthens and the intervertebral discs, which regain their natural buoyancy, exert a hydraulic force against downward p

Posture is thus maintained by a combination of forces that includes the inertial force of head balance, which counteracts the pull of the ne

There are, however, four main directions that relate specifically to the PNR system. Because these directions are so central to the working

Thus the forward balance of the skull on the spine plays a central role, not only in the maintenance of the posture of the head but of uprig
