Highlights from two recently published studies
People with non-specific neck pain have an increased cervical-ocular reflex (COR). The COR is the stabilization motion of the eye which is driven by neck proprioceptors, and is an objective, involuntary reflex. Study was performed with a rotating chair and an infra-red eye tracking device, so it’s not easily done.
TECH IDEA: Use COR benchmarking and tracking as a way to objectively document neck pain.

New research is showing that not only is manipulation good for pain and can improve posture, but that spinal stiffness is reduced as well. And there’s more.
From the conclusion of this systematic review: “These findings suggest involvement of an endogenous pain inhibition system mediated by the central nervous system, although this is yet to be investigated directly.”
