The gate-control theory of pain suggests that the brain prioritizes incoming pain signals based on their intensity and emotional context. According to this theory, messages from large nerve fibers (which carry non-painful touch and pressure sensations) can "close the gate" to the transmission of incoming pain signals, reducing the perception of pain. A back massage would likely activate these large nerve fibers in the spinal cord, which could help to reduce physical aches and pains. The other options listed (endorphins, adrenaline, and deactivation of pain receptors) may also play a role in pain perception, but they are not specifically mentioned in the gate-control theory.
