Meta Analysis
The Effects of Motor Imagery on Pain and Range of Motion in Musculoskeletal Disorders: A Systematic Review With Meta-analysis.
In recent years, there has been an increase in the use of motor imagery (MI) in the rehabilitation of musculoskeletal pain conditions. Across the literature, most reviews have yet to consider Laterality Judgement Task training as a form of MI method. This review aimed to evaluate the effectiveness of using MI as an adjunct to standard rehabilitation on the improvement of pain and range of motion parameters when managing patients with musculoskeletal pain conditions. ⋯ The results suggest that MI may be effective for pain relief and improvement in range of motion among chronic musculoskeletal pain conditions, although conclusion is based on a limited certainty of evidence as assessed using the GRADES (Grading of Recommendation, Assessment, Development and Evaluation) approach.

Meta Analysis
Effects of the OPRM1 A118G Polymorphism(rs1799971) on Opioids Analgesia in Cancer Pain: A Systematic Review and Meta-Analysis.
Although previous studies have demonstrated that the OPRM1 A118G polymorphism may influence the analgesia response to cancer pain, the results are inconsistent. In this article we aimed to fully examine the association between OPRM1 A118G (rs1799971) polymorphism and opioid analgesia by analyzing published information. This will provide information for better cancer pain management. ⋯ Our meta-analysis indicates that G allele (AG+GG) carriers of OPRM1 A118G polymorphism required more opioid analgesia in cancer pain management. The OPRM1 A118G polymorphism may help predict individuals' response to analgesia and achieve satisfactory cancer pain control.

To investigate the cross-sectional associations between musculoskeletal pain experience and measures of pressure and cold pain sensitivity in young adults from the Western Australian Pregnancy Cohort (Raine) Study. ⋯ This study provides the most extensive investigation of the relationship between musculoskeletal pain experience and pressure and cold pain sensitivity in young adults. Heightened cold pain sensitivity in those classified as "Medium" and "High" pain experience may suggest altered nociceptive processing and has implications for clinical management.

Observational Study
Predicting Procedure-Specific Morphine Consumption of Intravenous Patient-Controlled Analgesia with Random Effects Model Approach.
Surgical procedure is an important predictor for analgesic consumptions of intravenous patient-controlled analgesia (IV-PCA) for acute pain. ⋯ Adopted IV-PCA regimens for different surgical procedures are therefore strongly recommended and incorporated into postoperative acute pain management.

Observational Study
Influences of COMT rs4680 and OPRM1 rs1799971 Polymorphisms on Chronic Postsurgical Pain, Acute Pain and Analgesic Consumption After Elective Caesarean Delivery.
The main objectives of this study were to assess the effects of cathechol-O-methyl-transferase (COMT) rs4680 and μ-opioid receptor rs1799971 polymorphisms alone or genotype combinations on chronic postsurgical pain (CPSP), acute pain, and analgesic consumption after elective cesarean delivery in a Chinese cohort. ⋯ Our results indicate that cathechol-O-methyl-transferase rs4860 and μ-opioid receptor rs1799971 may not contribute to CPSP development after cesarean delivery. The genotype of rs1799971 affects postcesarean analgesic requirement, while the rs4680 do not. Additional larger studies are needed to confirm these findings.
