How does a chiropractic adjustment decrease pain?

• A. Movement activates mechanoreceptors which decreases nociception activation
• B. Increases inflammation
• C. Direct nerve damage
• D. Increases nociception

Answer: (A)

Movement from a chiropractic adjustment stimulates joint and tissue mechanoreceptors. This non-painful sensory input travels through A-beta fibers to the spinal cord and activates inhibitory interneurons that dampen the transmission of nociceptive signals from pain fibers. This gate-control effect reduces the amount of nociception reaching the brain, leading to less perceived pain. In addition, the mechanical stimulation can improve tissue perfusion and help clear pain-related chemical mediators, but the key idea is that mechanoreceptor activation gates nociceptive input, producing a pain decrease. The other options describe processes that would either increase pain or cause damage, which wouldn’t explain a reduction in pain after an adjustment.
