The Science and Philosophy
The Science behind the cause of somatic dysfunction in the form of spinal fixation or muscular imbalance is based on the discovery that the muscle spindle in the intrafusal fibers of the muscles of the body become attenuated - incorrectly set too short due to perceived trauma on the part of the sensory/motor nerve complex that travels between the muscle spindle and the spinal cord.
I have done my best to explain it in a manner that is comprehensible, I hope, to anyone who has long since forgotten or never learned what a muscle spindle is or does here.
Dr. Irvin Korr explains it in his own words here.
Here is another article that metaphorically and philosophically explains why I think these healing methods are especially important. Click here to read.
