Background: Musculoskeletal pain is one of the reasons for a musician's inability to play an instrument. An assessment of the localization, intensity, and interference of those complaints is important among musicians because of the risk of occupational disease. Assessment by validated tools is especially important and serves as an indicator to take up proper preventive or treatment actions. The aim of the study was to assess the prevalence of playing-related musculoskeletal disorders (PRMDs) and the relationships with PRMDs' impact on playing musical instruments among Polish professional orchestra musicians. Methods: The study was conducted on a group of professional orchestra musicians (age 37.19 ± 9.62 years), 99 (55%) women and 83 (45%) men. Work experience in professional orchestra was 18.3 ± 9.83 years and the reported years of playing musical instrument were 31.4 ± 9.50. The study used the online version of a musician-dedicated questionnaire, Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians of the Polish Population (MPIIQM-P). Results: In the study group, 89.9% of women and 83.1% of men had experienced playing-related pain in their lifetime. The most intense pain among the group with current playing-related musculoskeletal complaints (n = 85) was located in the neck area for 19 (22.4%). Conclusions: The results of the study indicate a high prevalence of playing-related musculoskeletal problems among professional musicians. [ABSTRACT FROM AUTHOR]

Background: The only complete and validated tool for evaluating professional orchestra musicians is the English-language Musculoskeletal Pain Intensity and Interference Questionnaire for professional orchestra Musicians (MPIIQM) questionnaire, which, in recent years, has been translated, adapted, and validated in other languages. The aim of the study was to validate the online version of the Polish version of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM-P). Materials and Methods: The group included 182 professional musicians. The respondents were asked to complete the MPIIQM-P, BPI, and QuickDash questionnaires twice within an interval of 4 days. The questionnaires were created in the web form creator—Google Form. Results: The EFA analysis showed a two-factor structure of the questionnaire consisting of factor 1—pain intensity and factor 2—pain interference. The internal agreement of the factors identified in the EFA analysis was measured by the α Cronbach index reaching from 0.813 to 0.913. The intraclass correlation coefficient of both factors ranged from 0.276 to 0.583. The analysis of convergent and divergent validity between the subscales of the questionnaire value ranged from 0.414 to 0.925. Conclusions: The online version of the MPIIQM-P questionnaire is a valid and reliable tool for the assessment of musculoskeletal pain and interference. The online MPIIQM-P questionnaire maintains the psychometric properties previously defined for the paper version. [ABSTRACT FROM AUTHOR]
