Which of the following is a major subluxation theory related to spinal cord function?

The major subluxation theory related to spinal cord function is centered around altered sensory input, often referred to as dysafferentation. This concept describes a state where there is abnormal afferent (sensory) input to the central nervous system, which can impact the functioning of the spinal cord and subsequently influence the whole nervous system. When subluxations occur, they can interfere with the normal transmission of sensory information, leading to a variety of dysfunctions.

Dysafferentation suggests that subluxations may alter the communication pathways between the periphery and the central nervous system, affecting not only sensory perception but also motor output and overall neural function. This theory emphasizes the importance of proper spinal alignment and its role in maintaining optimal neural communication and function.

In contrast, the other options focus on different aspects of health and Well-being. Psychosocial assessment pertains to emotional and social factors that impact health, but does not directly address how spinal cord function is influenced by subluxations. Trophic assessment relates to the nourishment and maintenance of tissues, while metabolic disturbance addresses biochemical processes in the body. Neither of these concepts fundamentally links to spinal cord function in the context of subluxation theory as clearly as the concept of altered sensory input does.
