Modulation of Spinal Nociceptive Excitability by Nociceptive‐Visual Interaction

Multisensory interactions between vision and nociception have been shown to affect nociceptive perception, but whether such interactions can also shape nociception-related motor processes is currently unknown. We investigated the potential influence of dynamic visual stimulation on the NWR in healthy participants. Results show that the presence of dynamic visual stimuli without any explicit task-related attentional or emotional valence can modulate the amplitude of the NWR without affecting the perceived intensity of the electrical stimulus eliciting the reflex.
