Sonographic peripheral nerve cross-sectional area in adults, excluding median and ulnar nerves: A systematic review and meta-analysis.

Introduction/aims: Although electromyography remains the "gold standard" for assessing and diagnosing peripheral nerve disorders, ultrasound has emerged as a useful adjunct, providing valuable anatomic information. The objective of this study was to conduct a systematic review and meta-analysis evaluating the normative sonographic values for adult peripheral nerve cross-sectional area (CSA).

Methods: Medline and Cochrane Library databases were systematically searched for healthy adult peripheral nerve CSA, excluding the median and ulnar nerves.

Prospective Evaluation of Pain Flares and Time Until Pain Relief Following Musculoskeletal Corticosteroid Injections.

Background: Corticosteroid injections are used ubiquitously within musculoskeletal medicine. One of the most common side effects is a postinjection pain flare, though little is known regarding this phenomenon.

Hypothesis: Some risk factors are related to postinjection pain flare following an ultrasound-guided corticosteroid injection.

Low theoretical fidelity hinders the research on health coaching for opioid reduction: A systematic review of randomized controlled trials.

Purpose: To systematically review the literature in order to evaluate the effects of health coaching on patients' reduction of opioid usage and opioid discontinuation. In addition, this systematic review investigated the effects of health coaching on pain intensity, physical function, and quality of life.

Methods: Four electronic databases (PubMed, Embase, Scopus, and PsychINFO) were searched from inception to December 2019.
