gate control theory (1965)

hypothesis proposed by Melzack and Wall to explain the highly variable and non-linear relationship between severity of injury and subjective response; central transmission of pain impulses (i.e. to sensory cortex) can be modulated by counterstimuli (e.g. tactile stimuli at peripheral tissues) which stimulate release of endogenous opioids within the spinal cord; transcutaneous electrical nerve stimulation (TENS) appears to work by this process
