Review Meta Analysis
A Systematic Review and Meta-Analysis of the Association between Perceived Injustice and Depression.
Perceived injustice is increasingly recognized as a risk factor for problematic recovery, with a growing body of evidence documenting its association with heightened pain, disability, medication use, anger and post-traumatic stress. The aim of this paper was to systematically review and critically appraise the association between perceived injustice and depressive symptomatology across a wide range of medical and mental health populations, including acute and chronic pain samples. A search of published, English language studies in the PubMed, EMBASE, CINAHL, and PsycINFO databases from 1990 to June 2020 was performed. ⋯ PROSPERO: CRD42019143465. PERSPECTIVE: This review demonstrates that in acute injury and chronic pain samples, perceived injustice is associated with depression. These findings could help clinicians in the field of pain and rehabilitation identify who may be at greater risk for a problematic recovery trajectory.

Pain intensity is a complex and dynamic experience. A focus on assessing patients' average pain levels may miss important aspects of pain that impact functioning in daily life. In this second of 3 articles investigating alternative indices of pain intensity derived from Ecological Momentary Assessments (EMA), we examine the indices' associations with physical and psychosocial functioning. ⋯ We suggest that alternative pain indices can provide new perspectives for understanding functioning in chronic pain. PERSPECTIVE: Alternative summary measures of pain intensity derived from EMA have the potential to help better understand patients' pain experience. Utilizing EMA for the assessment of Maximum Pain, Pain Variability, and Time in High Pain may provide an enhanced window into the relationships between pain and patients' physical and psychosocial functioning.

Review Meta Analysis
Investigating the true effect of psychological variables measured prior to arthroplastic surgery on post-surgical outcomes: a p-curve analysis.
Patients' presurgical psychological profiles have been posited to predict pain and function following arthroplastic surgery of the hip and knee. Nevertheless, findings are conflicting, and this may be rooted in biased reporting that makes the determination of evidential value difficult. This ambiguity may have negative consequences for researchers and governmental agencies, as these rely on findings to accurately reflect reality. ⋯ The results highlight the importance of patients' psychological profiles in predicting surgical outcomes, which represent a promising avenue for future treatment approaches. PERSPECTIVE: The effects of P-hacking are difficult to detect and might be at the root of conflicting findings pertaining to the predictive properties of presurgical psychological variables on postsurgical outcomes. P-Curve analysis allows the determination of evidential value underlying these relationships and detection of P-hacking to ensure that findings are not the result of selective reporting.

Review Meta Analysis
Systematic Review of Research Methods and Reporting Quality of Randomized Clinical Trials of Spinal Cord Stimulation for Pain.
This systematic review assessed design characteristics and reporting quality of published randomized clinical trials of spinal cord stimulation (SCS) for treatment of pain in adults and adolescents. The study protocol was registered with PROSPERO (CRD42018090412). Relevant articles were identified by searching the following databases through December 31, 2018: MEDLINE, Embase, WikiStim, The Cochrane Database of Systematic Reviews, and The Cochrane Central Register of Controlled Trials. ⋯ The review's findings suggest areas for improving the design of future studies and increasing transparency of reporting. PERSPECTIVE: This article presents a systematic review of research methods and reporting quality of randomized clinical trials of SCS for the treatment of various pain complaints. The review identifies deficiencies in both methodology and reporting, which may inform the design of future studies and improve reporting standards.

Review Meta Analysis
Exercise interventions for persistent non-specific low back pain - does matching outcomes to treatment targets make a difference? A systematic review and meta-analysis.
Exercise is a core treatment for persistent non-specific low back pain (NSLBP), but results from randomised controlled trials (RCTs) of exercise typically show only small to moderate standardised mean differences (SMDs) compared to nonexercise controls. The choice of primary outcome, and relationship to the specific targets of exercise may influence this. This systematic review aimed to explore whether primary outcomes match the exercise treatment targets used in NSLBP RCTs and the potential impact of matching on SMDs. ⋯ These exploratory findings may have implications for future teams developing RCTs of exercise for NSLBP and warrant further investigation in larger datasets. PERSPECTIVE: This review was an exploratory study that investigated the primary outcome and treatment targets used in RCTs of exercise for NSLBP. The SMDs of the matched group were descriptively larger than those of the unmatched group, but further analysis with larger sample sizes is required to have confidence in these results.
