Nociception affects motor output: a review on sensory-motor interaction with focus on clinical implications
PainSci notes on Nijs 2012:
Pain disrupts good coordination, and may also prevent “effective motor retraining”; Nijs et al. believes that we should “stop trying to restore normal motor control,” and propose that the focus should be on reducing pain instead.

OBJECTIVES: Research has provided us with an increased understanding of nociception-motor interaction. Nociception-motor interaction is most often processed without conscious thoughts. Hence, in many cases neither patients nor clinicians are aware of the interaction. It is aimed at reviewing the scientific literature on nociception-motor interaction, with emphasis on clinical implications.
METHODS: Narrative review.
RESULTS: Chronic nociceptive stimuli result in cortical relay of the motor output in humans, and a reduced activity of the painful muscle. Nociception-induced motor inhibition might prevent effective motor retraining. In addition, the sympathetic nervous system responds to chronic nociception with enhanced sympathetic activation. Not only motor and sympathetic output pathways are affected by nociceptive input, afferent pathways (proprioception, somatosensory processing) are influenced by tonic muscle nociception as well.
DISCUSSION: The clinical consequence of the shift in thinking is to stop trying to restore normal motor control in case of chronic nociception. Activation of central nociceptive inhibitory mechanisms, by decreasing nociceptive input, might address nociception-motor interactions.
