In addition to the neuro-musculo-skeletal problems observed with traumatically induced structural asymmetry, postural changes in the spine can be at the root of seemingly unrelated symptoms.
A recent paper in the Journal of Brain Structure and Function concluded:
“Results provide evidence of pathways linking upper cervical sensory afferents with CNS areas involved in autonomic and oromotor control, via the intermedius nucleus of the medulla. Disruption of these neuronal pathways could, therefore, explain the dysphagic and cardiorespiratory abnormalities which may accompany cervical dystonia and Whiplash Associated Disorders (WAD).”
COROLLARY: This may also provide a neuologic mechanism for some of the improvements observed by chiropractors and chiropractic patients who have seen a neck adjustment improve digestive problems.
