Meta Analysis
Are Ecological Momentary Assessments of Pain Valid and Reliable? A Systematic Review and Meta-analysis.
This systematic review and meta-analysis aimed to determine the level of evidence for the psychometric properties of Ecological Momentary Assessment (EMA) in populations with persistent pain. ⋯ Ecological momentary assessment of pain experience appears both valid and reliable. Although the levels of evidence were low or very low, these findings provide preliminary support for the use of EMA in clinical practice and research settings. Potential strengths of EMA include providing measures with greater ecological validity while also reducing recall bias, both pertinent in pain outcome measurement. More research, including higher-quality studies, is needed to demonstrate further support for EMA, including the need for establishing other types of validity.

This systematic review and meta-analysis aimed to determine the association between changes in patients' pain knowledge after pain science education (PSE) with treatment outcomes in people with chronic pain. ⋯ These findings do not support a short-term association between improvements in pain neurophysiology knowledge and better treatment outcomes in people with chronic pain. Increased understanding of how PSE works, as well as better ways to measure it, may help clinicians deliver more targeted education to help patients reconceptualize pain and promote engagement in active treatment strategies (eg, exercise).

Observational Study
Central Sensitization and Small-fiber Neuropathy Are Associated in Patients With Fibromyalgia.
To study the prevalence of small-fiber neuropathy (SFN) in a large cohort of patients with fibromyalgia (FM) and to better characterize the subset of patients with both FM and SFN. ⋯ Over the past 10 years, studies have shown that a significant proportion of patients with FM have signs of small nerve fiber impairment. The possible involvement of SFN, in the occurrence and presentation of clinical symptoms in FM patients, remains however unclear. This is the first study that showed an association between central sensitization and both small nerve fiber impairment and neuropathic pain features in FM patients, rather than a direct association between SFN and neuropathic pain.

Randomized Controlled Trial
Advantages of Transmuscular Quadratus Lumborum Block via Subfascial Approach versus Extrafascial Approach for Postoperative Analgesia after Laparoscopic Cholecystectomy: A Randomized Controlled Study.
We aimed to compare the analgesic effect and incidence of lower limb weakness of transmuscular quadratus lumborum (TQL) block via subfascial approach with that via extrafascial after laparoscopic cholecystectomy (LC). ⋯ TQL block via subfascial had the advantages of better analgesic effect and less lower limbs weakness after LC over that via extrafascial.

Review Meta Analysis
Comparative Effectiveness of Manual Therapy Interventions on Pain and Pressure Pain Threshold in Patients With Myofascial Trigger Points: A Network Meta-analysis.
Myofascial trigger points (MTPs) are one of the most important causes of musculoskeletal pain. Evidence has suggested a positive effect of manual therapy in the treatment of MTPs. However, a comprehensive review comparing the effect of different manual therapy techniques are lacking. Thus, we conducted a network meta-analysis of randomized controlled trials to determine the type of manual therapy technique that has the greatest positive influence in patients with MTPs. ⋯ Manual therapy interventions should be considered an effective strategy for pain and PPT in patients with MTPs. The results suggest that among the different manual therapy modalities, combined and afferent reduction techniques are the most effective for pain and PPT, respectively.
