HARP

The full pendulum swing is terminated (eccentrically) as hamstrings resist further swing and slow elongation. That energy has to go somewhere. If too much hamstring has been sacrificed to get range of motion (the golden calf) then there is no conduit to have that energy (via hamstring) pull the pelvis over the other leg stance hill. The green dotted line is hamstring deceleration of swing that recaptures the energy that the psoas had earlier put into the swing. Dampening also makes the dual pendulum non-chaotic whereas insufficient dampening allows chaos. Let’s look further at this dampening. If it happens too soon, then dampening swing early has a down pointing energy transfer path of the pelvis toward the floor. That’s not nice. The supine fast /slow knee extension test is looking at this part of the energy transfer mechanism. Fine tuning only by cutting tissue has fine adjustment difficulties. Ethanol selective focal nerve dysmyelination allows this to be fine tuned as contracture is not a thing. It is a mix of things which includes over reaction of reflexes superimposed on intentional movement. Considering each chunk of a continuous process in a nut shell? Is there a nut shell?

There is.
