Randomized Controlled Trial
A Brief Psychological Intervention for Chronic Pain in Primary Care: Examining Long-term Effects from a Pilot Randomized Clinical Trial.
Despite the existence of evidence-based psychological interventions for pain management, there are barriers that interfere with treatment engagement. A brief intervention integrated into primary care reduced barriers and showed promising benefits from pre- to post-intervention. However, it is unknown whether a brief intervention can provide long-term effects. The purpose of this study was to examine whether a brief psychological intervention offered benefits in pain severity, pain interference, pain catastrophizing, and depressive symptoms at 1- and 6-month follow-ups. ⋯ Findings suggest that a brief psychological intervention for chronic pain in primary care may offer longer-term benefits similar to that of lengthier interventions. Future studies should examine this through a randomized clinical trial with a larger sample size.

Randomized Controlled Trial Multicenter Study
Cooled Radiofrequency Ablation of Genicular Nerves Provides 24-Month Durability in the Management of Osteoarthritic Knee Pain: Outcomes from a Prospective, Multicenter, Randomized Trial.
To assess long-term outcomes of cooled radiofrequency ablation (CRFA) of genicular nerves for chronic knee pain due to osteoarthritis (OA). ⋯ In this subset of subjects, CRFA of genicular nerves provided durable pain relief, improved function, and improved quality of life extending to 24 months post procedure, with no significant safety concerns.

The clinical utility of combining the central sensitization (CS) inventory (CSI) with the pressure pain threshold (PPT) in assessing the effect of central sensitization on pain is unknown. This study aimed to investigate the effects of CSI, PPT, and their interaction on pain and the characteristics of clinical symptoms in patients with chronic musculoskeletal pain grouped according to the CSI score and PPT value. ⋯ Combined CSI and PPT may not fully allow a detailed classification of pain-related characteristics. The CSI may be clinically more useful for assessing the effect of CS on pain-related symptoms.
