The pain gate mechanism involves a delicate balance between the activity of small-diameter and large-diameter fibers. When the balance is disrupted, pain can occur. For example, if the small-diameter fibers are overactive or the large-diameter fibers are underactive, the gate may open, allowing pain signals to flood the brain. On the other hand, if the large-diameter fibers are overactive or the small-diameter fibers are underactive, the gate may close, reducing or eliminating pain. pain gate ddsc 018 link

Melzack and Wall's theory revolutionized this perspective by proposing that pain is actively regulated by the body itself. According to the Gate Control Theory, there is a neurological "gate" mechanism located in the dorsal horn of the spinal cord. This gate can either open to allow pain signals to pass through to the brain or close to block them, thereby modulating the perception of pain. This public link is valid for 7 days
