Abstract

Poor sleep quality is often comorbid with chronic pain. Research has also shown that poor and disrupted sleep may increase risk for chronic pain by promoting pronociceptive processes. This could occur through disrupted emotional modulation of pain since poor sleep can impact emotional experience and emotional experience modulates pain and nociception. To assess the pain system, nociceptive flexion reflexes (spinal level), pain-evoked potentials (supraspinal level), and perceived pain were recorded during an emotional picture-viewing task in which 37 healthy individuals received painful electric stimulations. The Pittsburgh Sleep Quality Index assessed sleep quality. Individuals with poor sleep quality were unable to inhibit signals at the spinal level in response to positive pictures, whereas emotional modulation of supraspinal nociception and pain perception remained unaffected by sleep quality. This suggests poor sleep quality may promote pronociception by impairing descending, emotional modulation of spinal nociception.
