Rescue medication is commonly offered to participants in placebo-controlled trials of analgesic drugs. The use of pain medication in addition to the placebo or experimental drug may complicate the interpretation of effects and tolerability, but this issue has received little methodological attention. This study examined the handling and reporting of rescue and concomitant analgesic use in trials of pharmacotherapy for neuropathic pain and low back pain. ⋯ More than one-third of the trials permitting rescue medication did not report the actual rescue drug consumption, and over half of the trials allowing concomitant analgesics did not report whether intake changed during the trial. Only 22 (19%) of the trials permitting rescue medication included complete information about whether rescue medication was used as an outcome, specified the drugs used, specified how consumption was assessed and measured, and reported and analyzed the use of rescue medication in each trial arm. Our findings suggest that poorly described procedures and incomplete reporting are likely to hinder the interpretation, critical appraisal, and replication of trial results.

Review Meta Analysis
The association between the weight of schoolbags and low back pain among schoolchildren. A systematic review, meta-analysis and individual patient data meta-analysis.
The objective of this study was to determine whether carrying a heavy schoolbag is associated to a higher prevalence of low back pain (LBP). ⋯ This systematic review, with a meta-analysis and an IPD meta-analysis, failed to find a link between schoolbags weighing ≥ 10% of body weight and LBP among schoolchildren aged 9 to 16. Further longitudinal studies, with large samples, long follow-up periods, and rigorous methods taking into account duration of carry and the physical capacity of each subject, are required in this field.

Randomized Controlled Trial Comparative Study
Moderators of mindfulness meditation, cognitive therapy, and mindfulness-based cognitive therapy for chronic low back pain: A test of the Limit, Activate and Enhance model.
This study examined psychosocial pain treatment moderation in a secondary analysis of a trial that compared cognitive therapy (CT), mindfulness-meditation (MM), and mindfulness-based cognitive therapy (MBCT) for chronic low back pain (CLBP). The Limit, Activate, and Enhance (LA&E) model of moderation provided a framework for testing a priori hypotheses. Adult participants (N = 69) with CLBP completed a pretreatment assessment of hypothesized moderators: pain catastrophizing, brain state as assessed by electroencephalogram, mindful observing, and nonreactivity. ⋯ Theory-driven moderation research has the capacity to inform the development of patient-treatment matching algorithms to optimize outcome. PERSPECTIVE: This study presents preliminary findings from theory-driven tests of the moderators of mindfulness meditation, cognitive therapy, and mindfulness-based cognitive therapy for chronic low back pain. The results of such analyses may inform the understanding of for whom various evidence-based psychosocial pain treatments may engender the most meaningful benefits.

Observational Study
Dedicated emergency department physical therapy is associated with reduced imaging, opioid administration, and length of stay: A prospective observational study.
Emergency department based Physical Therapy (ED-PT) has been practiced globally in various forms for over 20 years and is an emerging resource in the US. While there is a growing body of evidence suggesting that ED-PT has a positive effect on a number of clinical and operational outcomes in patients presenting with musculoskeletal (MSK) pain, there are few published narratives that quantify this in the US. Although there are international papers that offer outcome data on reduction of pain, imaging, throughput time, and the ability of physical therapists to appropriately manage MSK conditions in the ED setting, most papers to date have been descriptive in nature. The purpose of this study is to assess the impact of ED-PT on imaging studies obtained, rates of opioids prescribed, and ED length of stay. ⋯ In our experience, being seen by a physical therapist for MSK pain within the ED was associated with reduced use of imaging and time spent in the ED. Patients seeing a Physical Therapist were also less likely to receive an opioid prescription within the ED, a potentially significant finding given the need for opioid reduction strategies.

Review Comparative StudyEvidence versus advocacy, as related to radiofrequency denervation in the treatment of chronic low back pain and the MINT trials.
In 2017, JAMA: Journal of the American Medical Association published the results of the MINT trials, prospective research involving 681 patients, all of whom received exercise therapy for low back pain. Half of the patients were randomized to additionally receive radiofrequency denervation (RFD) treatment. 88% of patients completed the 3-month follow-up, and 77% completed the 12-month follow-up. In this context, RFD provided no added benefit over the baseline of exercise therapy. ⋯ Noteworthy, there was no published response from the MINT trial investigators to the Daring Discourse criticisms, either in the aforementioned example or in downstream venues where some of the same Daring Discourse authors continued their widely disseminated criticisms of the JAMA/MINT trials report. We believe that these actions taken by the Daring Discourse authors and RAPM have unfairly tipped the scales in the evaluation and application of RFD treatment of low back pain. In our commentary, we discuss: (1) the challenges associated with using clinical trials to predict clinical efficacy, (2) appropriate and inappropriate uses of postpublication commentary on original research findings, (3) the use of inappropriate commentary (and related means) to alter clinical practice in the presence of contradictory research findings, and (4) potential conflicts of interest related to the authors' and Journal's publication of the unopposed MINT trials criticism.
