OBJECTIVES: To (1) summarize pooled prevalence and incidence rates of concussion by type of sport and (2) synthesize the differences in prevalence or incidence rates of concussion by type of sports in terms of sex, age, type of session, and level of competition. DESIGN: An overview of systematic reviews with meta-analysis. LITERATURE SEARCH: CINAHL, Embase, Epistemonikos, PubMed, Scopus, SPORTDiscus, and the Cochrane Library databases were searched. STUDY SELECTION CRITERIA: Systematic reviews with meta-analyses reporting pooled incidence or prevalence of sport-related concussion. DATA SYNTHESIS: AMSTAR 2 was used to assess the methodological quality of reviews. Overlap between reviews was calculated. RESULTS: Ten systematic reviews with meta-analysis were included, all evaluating incidence rates of concussion. There were no meta-analyses of concussion prevalence. Concussions seem to have a higher incidence in rugby, snowboarding, ice hockey, and American football. In reviews that explored sex-based differences across subgroups, there was a higher incidence rate of concussion in baseball-softball, basketball, and soccer in females compared to males. There were no age subgroups analyzed. The incidence of concussions was higher during games compared to practice in American football, ice hockey, rugby, and soccer. Amateur rugby had higher concussion rates compared to professional rugby. CONCLUSIONS: Rugby, snowboarding, ice hockey, and American football had the highest incidence rate of concussion when no other differences (eg, type of session) were considered. However, important methodological flaws were detected, such as the lack of use of the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) system and subgroups for specific factors (eg, age groups).

OBJECTIVE: We aimed to summarize the evidence of the effects of pain neuroscience education delivered alone or combined with other interventions for chronic pain. DESIGN: An overview of systematic reviews with meta-analysis. LITERATURE SEARCH: CINAHL (via EBSCOhost), Embase, PsycINFO (via ProQuest), PubMed, and the Cochrane Library were searched from their inception to November 14, 2022. STUDY SELECTION CRITERIA: Systematic reviews (SRs) with meta-analyses including randomized clinical trials. The outcomes were pain and psychological symptoms. DATA SYNTHESIS: AMSTAR 2 assessed the methodological quality of SRs. The primary study overlap was evaluated by calculating the corrected covered area (CCA). RESULTS: We included 8 SRs including 30 meta-analyses of interest that comprised 28 distinct clinical trials. In some meta-analyses, pain neuroscience education delivered alone or combined with other interventions was more effective than control interventions for reducing pain intensity, pain catastrophizing, kinesiophobia, anxiety symptoms, and depression symptoms at some time points. However, other meta-analyses found a lack of effects of pain neuroscience education, and there were inconsistencies between meta-analyses covering the same outcome. The methodological quality of all SRs was critically low. The overlap, including all SRs, was high (CCA = 13%), and very high for SRs covering trials on chronic low back pain (CCA = 40%), chronic spine pain (CCA = 27%), and fibromyalgia (CCA = 25%). CONCLUSION: It is impossible to make clear clinical recommendations for delivering pain neuroscience education based on current meta-analyses. Action is needed to increase and improve the quality of SRs in the field of pain neuroscience education. J Orthop Sports Phys Ther 2023;53(6):1-16. Epub: 10 May 2023. doi:10.2519/jospt.2023.11833 .

Objective: To summarize (1) the emotions, cognitions, and behaviors of people who are living with musculoskeletal disorders related to symptoms and (2) the interactions of emotions, cognitions, and behaviors with the person's environment (family, social, and work roles)., Design: An umbrella review of qualitative research syntheses and meta-summaries (metasynthesis, meta-ethnographies, meta-aggregation, meta-summary)., Literature Search: We searched CINAHL, EMBASE, PsycARTICLES, PsycEXTRA, PsycINFO, PubMed, and PubPsych from database inception to January 2021. We also searched gray literature via Open Grey and Google Scholar., Study Selection Criteria: We included qualitative evidence syntheses evaluating adults with musculoskeletal disorders, based on the multidimensional diagnostic criteria for acute and chronic pain. Emotions, cognitions, and behaviors were the phenomenon of interest., Data Synthesis: We developed 3 categories of themes ([1] emotions, [2] cognitions, and [3] behaviors) for each objective. We selected the 3 most common emotions, cognitions, and behaviors that appear as themes in our narrative synthesis., Results: We included 20 qualitative evidence syntheses that retrieved 284 original qualitative studies. Despair, distress, and fear were the main emotions reported by people living with musculoskeletal disorders. The alterations of the self and how people described their symptoms, what caused them, and how the symptoms impacted their lives were the most common cognitions. Cognitive strategies (ie, acceptance) and perceptions about social support emerged. People often used passive behaviors (eg, social isolation or hiding symptoms) to cope with the challenges that arose related to musculoskeletal symptoms. However, some people actively faced their symptoms, planning their activities or practicing them despite their symptoms., Conclusion: Clinicians who support people living with musculoskeletal disorders should consider (1) assessing other emotions than pain-related fear (eg, despair and distress), (2) observing their cognitive responses (ie, acceptance), and (3) evaluating what type of behaviors people use (eg, active or passive).

Objective: To find out which interventions enhance pain self-efficacy in people with chronic musculoskeletal pain and to evaluate the reporting of interventions designed to enhance pain self-efficacy., Design: Intervention systematic review with meta-analysis., Literature Search: PubMed, Embase, Scopus, PsycINFO, CINAHL, PEDro, and the Cochrane Central Register of Controlled Trials were searched from inception up to September 2019., Study Selection Criteria: Randomized controlled trials evaluating pain self-efficacy as a primary or secondary outcome in chronic musculoskeletal pain., Data Synthesis: We used the Cochrane risk of bias tool and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to evaluate the risk of bias and the certainty of the evidence, respectively., Results: Sixty randomized controlled trials were included (12 415 participants). There was a small effect of multicomponent, psychological, and exercise interventions improving pain self-efficacy at follow-ups of 0 to 3 months, a small effect of exercise and multicomponent interventions enhancing pain self-efficacy at follow-ups of 4 to 6 months, and a small effect of multicomponent interventions improving pain self-efficacy at follow-ups of 7 to 12 months. No interventions improved pain self-efficacy after 12 months. Self-management interventions did not improve pain self-efficacy at any follow-up time. Risk of bias, the nature of the control group, and the instrument to assess pain self-efficacy moderated the effects of psychological therapies at follow-ups of 7 to 12 months. The certainty of the evidence for all included interventions was low, due to serious risk of bias and indirectness. No trial reported the intervention in sufficient detail to allow full replication., Conclusion: There was low-quality evidence of a small effect of multicomponent exercise and psychological interventions improving pain self-efficacy in people with chronic musculoskeletal pain.
