Randomized Controlled Trial
Can internet-delivered pain management programs reduce psychological distress in chronic pain? Exploring relationships between anxiety and depression, pain intensity, and disability.
Adults with chronic pain who also report high pain intensity and disability are more likely to experience depression and anxiety symptoms. The present study examined changes in anxiety and depression symptoms after an Internet-delivered pain management program based on baseline pain intensity and disability severity categories. ⋯ These findings suggest that emerging Internet-delivered pain management programs can lead to reductions in psychological distress even when pain intensity and disability are severe or do not improve with treatment. This indicates the value of such treatments in treating distress and improving mental health in people with chronic pain.

Meta Analysis
Size reduction of the right amygdala in chronic pain patients with emotional stress: A systematic review and meta-analysis.
The structural impact of chronic pain on amygdala in chronic pain (CP) patients remains unclear, although major depression and anxiety are known to be associated with its increase and decrease in size, respectively. This study aimed at examining the relationship between emotional stress and amygdala size in CP patients. The effects of mediating and moderating variables were also examined. ⋯ Besides, pain from a single body region was more likely to impact the amygdala size compared to diffuse pain (P = .02). Regression analysis revealed no significant association between continuous variables (age, gender, pain duration/intensity) and amygdala size. Our findings demonstrated that emotional stress was associated with a reduced right amygdala size in CP patients.

Randomized Controlled Trial
Preventive effect of an intervention program with increased physical activity on the development of musculoskeletal pain in community-dwelling older adults: A randomized controlled trial.
To examine whether compared with a program without increased physical activity, an intervention program with increased physical activity can prevent the development of musculoskeletal pain in community-dwelling older adults. ⋯ The intervention program with increased physical activity prevented the development of musculoskeletal pain and improved cognitive function, physical activity levels, and psychological status more effectively than the program without increased physical activity. Our intervention program may be an effective pain prevention approach for older adults.

Clinical outcomes following lumbar medial branch radiofrequency ablation (RFA) have been inconsistent. One possible reason is less-than-optimal placement of the electrode along the medial branch at the lateral neck of superior articular process (SAP). Needle angles that define optimal placement (i.e., parallel to the medial branch) may be helpful for consistent technical performance of RFA. Despite its importance, there is a lack of anatomical studies that quantify RFA needle placement angles. ⋯ Variability of needle angles suggest a standard "one-size-fits-all" approach may not be the optimal technique. Future research is necessary to determine optimal patient-specific needle angles from a more detailed and granular analysis of fluoroscopic landmarks.
