Abstract

Background
This study investigated the prevalence and associated factors of musculoskeletal pain among professional dancers who experienced a lapse in group practice due to coronavirus disease 2019.
Methods
General characteristics, practice time, region of musculoskeletal pain due to injury using the visual numeric scale (VNS), and causative motion were surveyed among professional dancers. Pain of VNS 0 to 3 was categorized as “no or minor,” 4 to 6 was categorized as “moderate,” and 7 to 10 was categorized as “severe.” The causal motions of musculoskeletal pain were analyzed according to body region. Factors other than motion associated with pain were also analyzed.
Results
In total, 368 participants were included. In the univariate analysis, age and practice time were positively associated with “moderate” pain. Practice time, dance experience, and postural accuracy were positively associated with “severe” pain, as was performing Korean traditional dance. In the multivariable analysis, practice time, group practice, and age were positively associated with pain of VNS 4 to 10, and practice time, group practice, and Korean traditional dance were positively associated with pain of VNS 7 to 10.
Conclusion
Among the factors related to dancer training, practice time, group practice, and dance type affect the occurrence of pain.

  Fig. 1. The pattern of association between practice time (hours per week) and musculoskeletal pain in the logistic regression model. (A) Expected probability of “moderate to severe” pain by practice time. (B) Odds ratio for “moderate to severe” pain by practice time. (C) Expected probability of “severe” pain by practice time. (D) Odds ratio for “severe” pain by practice time. “Moderate to severe” pain refers to pain of 4–10 on visual numeric scale (VNS). “Severe” pain refers to pain of 7–10 on VNS.
