The gate control theory of pain proposes that pain signals are transmitted through small nerve fibers called C fibers, and their transmission can be modulated by signals from large A fibers. When A fibers are activated, they inhibit the transmission of pain signals through the spinal cord and reduce the perception of pain. Scratching or itching around a painful spot can activate large A fibers, which can shut the gate and reduce the pain signals transmitted by C fibers. Therefore, the resulting relief is due to the activation of A fibers to shut the gate.
