Quantitative Postural Evaluation in Orchestral Musicians (the OPErA Project): Protocol for a Cross-Sectional Study.
Article in JMIR research protocols, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Musicians are at high risk for playing-related musculoskeletal disorders due to prolonged static postures and asymmetrical movements. Despite the prevalence of these disorders, objective ergonomic assessments in orchestral settings are limited. Objective: The primary aim of this study (the Orchestral Posture Ergonomic Assessment [OPErA] project) is to quantify postural deviations in professional orchestral musicians, with and without their instruments, and to investigate their association with pain and pain leading to performance limitation. Secondary aims include exploring demographic, clinical, and occupational factors associated with these outcomes. Methods: This cross-sectional study will enroll 250 professional musicians from Italian orchestras, excluding pianists. Postural assessments will be conducted in 2 phases-without and with the instrument-using the Physical Analyzer Portable, a device for calibrated photo acquisition. Anatomical landmarks will be marked with electrocardiogram electrodes to measure inclination, rotation, and asymmetries in the frontal and sagittal planes. Pain and disability will be evaluated using validated questionnaires (Quick Disabilities of the Arm, Shoulder and Hand [QuickDASH]; Modified Oswestry Disability Index; and Neck Disability Index). Statistical analysis will include descriptive statistics, 2-tailed t tests, chi-square tests, and regression models to explore associations between posture and pain. Results: The protocol was approved in November 2022 and funded in 2025. Data collection was conducted from May 2023 to April 2026. By the time of manuscript submission (February 2026), 240 of the target 250 participants had been enrolled. Data analysis is ongoing, and the results are expected to be published in July 2026. Conclusions: This study will provide quantitative insights into postural deviations and their relationships with pain and pain leading to performance limitation. The findings are expected to identify instrument-specific associated factors and compensatory behaviors, supporting the development of targeted ergonomic interventions and preventive strategies for musicians' health.
