Quantitative Postural Evaluation in Orchestral Musicians (the OPErA Project): Protocol for a Cross-Sectional Study.

Area of Science:

• Music Performance Science
• Ergonomics and Biomechanics
• Occupational Health

Background:

• Orchestral musicians face high risks of playing-related musculoskeletal disorders.
• Objective ergonomic assessments in orchestral settings are currently limited.
• Prolonged static postures and asymmetrical movements contribute to these disorders.

Purpose of the Study:

• To quantify postural deviations in professional orchestral musicians, with and without instruments.
• To investigate the association between postural deviations, pain, and performance limitations.
• To explore demographic, clinical, and occupational factors related to these outcomes.

Main Methods:

• A cross-sectional study involving 250 professional musicians (excluding pianists).
• Postural assessments using the Physical Analyzer Portable device to measure inclination, rotation, and asymmetries.
• Validated questionnaires (QuickDASH, Modified Oswestry, Neck Disability Index) to assess pain and disability.

Main Results:

• Data collection is ongoing, with 240 of 250 participants enrolled by February 2026.
• Data analysis is in progress, with results anticipated in July 2026.
• The study is expected to yield quantitative insights into postural deviations and their correlation with pain.

Conclusions:

• This research will offer quantitative data on postural deviations in musicians.
• Findings are expected to identify instrument-specific factors and compensatory behaviors.
• The study aims to support the development of targeted ergonomic interventions and preventive strategies for musicians' health.
