Many studies investigating the attenuation of pain by psychological means have confounded cognitive factors with motoric factors. Two experiments were performed to investigate the extent to which intentional movements alone can attenuate experimental pain. Reciprocal finger movements of the limb contralateral to a noxiously stimulated limb were found to result in significantly longer tolerance times and significantly lower pain intensity ratings when visual attention was directed to and away from the spatial location of the noxious stimulation.
