Prevalence of musculoskeletal chest pain in the emergency department: a systematic review and meta-analysis.

Objectives: Our objective was to systematically review and meta-analyse relevant studies to determine the prevalence of musculoskeletal chest pain in the emergency department.

Methods: This review was constructed while confirming to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. PubMed, Cochrane Library, SCOPUS, Science Direct, and OVID were systematically searched from their inception to January 19, 2020, to identify observational studies, where the prevalence of musculoskeletal causes of chest pain was reported in isolation or in combination with other causes or could be calculated from the available data.

Objective: To assess the effects of weight, position, and time of school bag carriage in static and dynamic conditions on cervical and shoulder posture in adolescent students.
