Population

Postoperative pain was associated with attenuated electrodermal responses; cross-sectional data leave open biomarker utility for autonomic assessment.
Do physiologic maneuvers to perturb the autonomic nervous system alter electrodermal response in patients with clinical pain compared to controls?
Clinical pain in postoperative patients is associated with an attenuated electrodermal response to autonomic maneuvers.
Naifeh et al. (1983) studied this question.
