Troubles musculosquelettiques, pratique instrumentale et ressentis des musiciens d’orchestre professionnels en confinement dû à la COVID-19

INTRODUCTION: Professional orchestra musicians frequently suffer from musculoskeletal disorders related to their working conditions. In the spring of 2020, the lockdown and the interruption of their professional activities because of the COVID-19 pandemic could have presented an opportunity for them to recuperate but could also have increased their professional uncertainty and been a source of negative emotions. OBJECTIVE: The first objective is to evaluate the evolution of musicians’ musculoskeletal disorders in relation to the interruption of their professional activities due to COVID-19. The second is to examine the impact of professional uncertainty caused by the pandemic on their instrument practice as a function of the emotions it generated. METHOD: A questionnaire concerning instrument practice and musculoskeletal disorders was completed by 439 French orchestra musicians in 2019 (period of professional activity). During lockdown (April 2020), a second questionnaire measuring these variables as well as professional uncertainty, emotions, emotional exhaustion, and the lockdown experience was completed by 172 musicians. RESULTS: Instrument practice and musculoskeletal disorders decreased between the periods of activity and lockdown. Professional uncertainty during lockdown correlated with negative emotions. Emotional exhaustion mediated the relations between uncertainty and the effort perceived when practicing one's instrument on the one hand and the pleasure experienced during practice on the other. CONCLUSION: For orchestra musicians in lockdown, uncertainty was related to negative emotions. Playing their instrument required more effort and was not associated with well-being, emphasizing the difficulties regarding the resumption of their professional activity in conditions which would limit the risk of injury.
