It has previously been demonstrated that cervical radiofrequency neurotomy (cRFN) resolves psychological distress and anxiety. It is unknown if cRFN also improves or reduces a broader spectrum of psychological substrates now commonly identified in chronic whiplash, such as post-traumatic stress disorder (PTSD) and pain catastrophizing. To determine if reducing pain in the cervical spine (following cRFN) significantly reduces psychological features (distress, pain catastrophizing and post-traumatic stress symptoms) in individuals with chronic WAD. Tertiary spinal intervention centre in Calgary, Alberta, Canada. Prospective observational study of consecutive patients. Fifty-three individuals with chronic whiplash associated disorder symptoms (Grade 2). Cervical RFN following successful response to cervical facet joint blockade.

However, not all individuals respond to cRFN, and it is unknown which clinical features predict successful response to cRFN. This prospective cohort study investigated 53 individuals with chronic WAD (36 female, 17 male; mean age = 44.7 ± 10.9 (SD) years) who underwent cRFN. Predictor variables measured at baseline (prior to RFN) included self-reported pain (VAS), disability (NDI), post-traumatic stress symptoms (PDS), pain catastrophizing (PCS), and measures of sensory hypersensitivity (pressure and cold pain thresholds). The outcome measure was perceived Global Rating of Change (where scores ≥ 4 were classified as a successful response) 3 months post-cRFN. Univariate logistic regression demonstrated that lower levels of disability and pain catastrophizing were associated with successful response of cRFN (both P < 0.05). Multivariable logistic regression demonstrated that low levels of pain catastrophizing and disability remained significant predictors of a successful response to cRFN (both P < 0.05). Low levels of pain catastrophizing and disability independently predicted a successful response to cRFN in patients with chronic WAD.
