The objective of this study was to determine the effectiveness of cervical medial branch radiofrequency neurotomy (RFN) performed by two practitioners trained according to rigorous guidelines. ⋯ Cervical RFN can be very effective when performed in a rigorous manner in appropriately selected patients. Chronic neck pain, mediated by the cervical medial branches, can be temporarily, but completely, relieved and patients fully restored to desired activities of daily living, if treated with RFN.

The primary objectives of the current study were to 1) confirm the three-factor model of the Pain Catastrophizing Scale (PCS) items in a Japanese sample and 2) identify the catastrophizing subdomain(s) most closely associated with measures of pain and functioning in a sample of individuals with chronic pain. ⋯ The findings support the cross-cultural generalizability of the three-factor structure of the PCS and indicate that the PCS-assessed catastrophizing subdomains provide greater explanatory power than the PCS total score for understanding pain-related functioning.
