This review aimed to explore the processes that underlie the main and the buffering effect of social support on decreased pain experience. ⋯ This review presents evidence that the stress-buffering effect is more often able to account for the relationship between social support and pain experience. Moreover, findings suggest the critical significance of stress appraisal and attenuated stress systems in linking social support to aspects of reduced pain experience. Findings implicate the role of integrating perceived support and intimacy in support-oriented interventional trials for chronic pain.

Given high levels of traumatic stress for low-income, inner-city women, investigating the link between posttraumatic stress disorder (PTSD) and pain is especially important. ⋯ Results suggest that presence of PTSD symptoms is associated with elevated acute pain responses both indirectly via psychosocial vulnerability factors and directly, independent of the psychosocial factors assessed. Resilience factors did not play a significant role in determining acute pain responses. Consistent with conservation of resources theory, the negative effects of vulnerability factors outweighed the positive effects of resilience factors.

Ultrasound-guided Pulsed Radiofrequency in the Management of Thoracic Postherpetic Neuralgia: A Randomized, Double-blinded, Controlled Trial.
This study was designed to evaluate the efficacy and safety of ultrasound-guided pulsed radiofrequency (PRF) for the intercostal nerves (ICNs) in the management of thoracic postherpetic neuralgia. ⋯ Ultrasound-guided PRF for ICNs in combination with pharmacotherapy seems to be a safe and effective treatment modality for postherpetic neuralgia.

Randomized Controlled Trial
Using Illness Perceptions to Cluster Chronic Pain Patients: Results From a Trial on the Chronic Pain Self-Management Program.
The aims of our study were (1) to identify possible subgroups of individuals with chronic pain based on their illness perceptions (IPs); (2) to examine whether these subgroups differed in health status and health expenditure; and (3) to examine whether the subgroups differed in their response to participation in a lay-led Chronic Pain Self-Management Program (CPSMP). ⋯ Clusters based on IPs meaningfully distinguished individuals with chronic pain on health measures and outcome of participating in the CPSMP, and may prove useful in future studies to understand responses to treatment.
