A mismatch between the brain's motor control and sensory systems has been suggested as one mechanism whereby maladaptive neuroplastic changes contribute to the experience of chronic pain. Several studies have investigated this hypothesis by artificially inducing a state of sensory-motor incongruence using mirrors. The data to date appear to suggest that creating an environment of sensori-motor incongruence induces various sensory changes and feeling of peculiarity, however the effect on pain is less clear. The aim of this study was to test the hypothesis that healthy participants would demonstrate reduced pain thresholds and report greater intensity of pain in a condition of induced sensory motor incongruence compared to conditions that did not promote incongruence.
