Dor musculoesquelética e sua influência na performance musical entre os primeiros e segundos violinos de orquestras de câmara infanto-juvenis

Abstract

8 Introduction. Musculoskeletal changes are commonly found in young musicians in orchestras. However, few studies are found specifying the musculoskeletal pain of violinist musicians associating the movements related to the handling of the bow among the groups of the first violins in relation to the second. This study aimed to identify and relate the musculoskeletal pain indicators perceived by violin students in different body regions, associating age, sex, time and frequency dedicated to studies with the musical instrument. Objective. To compare the levels of pain and musculoskeletal changes in first and second violins of juvenile chamber orchestras. Methods. A cross-sectional observational study of a quantitative character was carried out on 74 instrumentalists from children and youth chamber orchestras aged between 12 and 17 years old who had the violin as their main instrument. The sample of this study was a convenience type, where the participants completed a self- administered questionnaire called “Musculoskeletal Pain Intensity and Interference Questionnaire for Professional Orchestra Musicians” (Brazilian version), in addition to a body map divided into 45 parts, 22 associated with the previous region ( 1 to 22) and 23 associated with the posterior region (23 to 45) specifying each body segment in order to identify the region that most bothered him and would interfere in his activities. Results. When comparing the group of first and second violins, we did not observe significant differences between age, practice time and time working at the professional level, thus showing that the groups were homogeneous. Regarding the activity day in the orchestra, 100% of the participants, exercised their activities in a partial period. There was a statistically significant difference between the average hours of time in the orchestra of the first violinists 15.7 (± 1.6) and second violinists 16.5 (± 1.9) (p = 0.02). A correlation was observed between the time of practice and the number of areas indicated on the body pain map (rho = 0.30; p = 0.03); as well as a correlation between the time of profession and the number of areas indicated on the body pain map (rho = 0.39; p = 0.01).Conclusion. The study identified a statistically significant difference in relation to complaints of musculoskeletal pain in the right shoulder presented by the second violins in relation to the first, possibly due to the movement associated with the handling of the bow performed by this group that needs to achieve different notes than the group of second violins of a children's and youth chamber orchestra, aged between 12 and 17 years old.
