Who states that the same mechanisms are involved when the viscera produce a disturbance in the cord, with somatic involvement being secondary?

The focus of the question is on the assertion that disturbances in the visceral organs can influence the spinal cord, with subsequent effects on somatic structures being secondary. Korr's work is pivotal in this context, as he emphasized how visceral dysfunctions can lead to somatic disturbances through complex neurophysiological pathways. His research supports the idea that visceral afferents—nerves carrying signals from internal organs—can affect the central nervous system and subsequently lead to somatic issues, thus positioning these issues as secondary to the initial visceral disturbance.

The primary rationale for selecting Korr lies in his contribution to understanding the interconnectedness of the nervous system and its impact on both visceral and somatic domains. This view aligns with chiropractic philosophy, particularly in how practitioners assess and treat conditions that may originate from visceral dysfunction, ultimately affecting musculoskeletal health. Korr's theories advocate for a holistic view of health in which the relationship between organ systems and musculoskeletal function is critical.
