Psychologic Factors Are Related to Some Sensory Pain Thresholds but Not Nociceptive Flexion Reflex Threshold in Chronic Whiplash

Abstract

We have demonstrated that psychologic factors have some association with sensory hypersensitivity (cold pain threshold measures) in chronic whiplash but do not seem to influence spinal cord excitability. This suggests that psychologic disorders are important, but not the only, determinants of central hypersensitivity in whiplash patients.
