There is no shortage of theories to explain the role of the subluxation in disease and the effect of the adjustment in relieving symptomatology. The autonomic nervous system has often been invoked in constructing mechanisms to account for the effects of spinal dysfunction. Recent investigations justify the attention which has been focused on this component of the nervous system.
Recent neuroscience research supports a neurophysiologic rationale for the concept that aberrant stimulation of spinal or paraspinal structures may lead to segmentally organized reflex responses of the autonomic nervous system, which in turn may alter visceral function.
