In chronic neural dysfunction with persistent segmental dysfunction and pilomotor, sudomotor, and vasomotor changes, which concept describes increased nerve recruitment and pain sensitivity?

In chronic neural dysfunction with persistent segmental dysfunction and pilomotor, sudomotor, and vasomotor changes, which concept describes increased nerve recruitment and pain sensitivity?

• A. The Original Chiropractic Model "BOOP"
• B. Facilitation
• C. Segmental Dysfunction
• D. Nerve Compression

Answer: (B)

Facilitation is the idea that persistent input from a damaged or dysfunctional cervical segment can make the spinal neural network more excitable. When a segment stays dysfunctional, the dorsal horn neurons become sensitized and easier to activate. That means more nerve fibers are recruited in response to stimuli, and the same input produces a larger pain response than normal. This heightened sensitivity is why you see ongoing pain, hyperalgesia, and even allodynia, along with autonomic signs like pilomotor (goosebumps), sweating, and vascular changes. The autonomic symptoms reflect sympathetic–nociceptive interactions driven by this increased spinal excitability. So, this scenario fits facilitation because it links chronic segmental dysfunction to an amplified neural and autonomic response, rather than attributing it solely to mechanical compression or to a static, isolated segment impairment. The other concepts don’t capture the dynamic increase in neuron recruitment and pain sensitivity that facilitation describes.
