To describe the incidence rate, severity, burden and aetiology of medical attention and time-loss injuries across five consecutive seasons at a professional ballet company.
Medical attention injuries, time-loss injuries and dance exposure hours of 123 professional ballet dancers (women: n=66, age: 28.0±8.3 years; men: n=57, age: 27.9±8.5 years) were prospectively recorded between the 2015/2016 and 2019/2020 seasons.
The incidence rate (per 1000 hours) of medical attention injury was 3.9 (95% CI 3.3 to 4.4) for women and 3.1 (95% CI 2.6 to 3.5) for men. The incidence rate (per 1000 hours) of time-loss injury was 1.2 (95% CI 1.0 to 1.5) for women and 1.1 (95% CI 0.9 to 1.3) for men. First Soloists and Principals experienced between 2.0-2.2 additional medical attention injuries per 1000 hours and 0.9-1.1 additional time-loss injuries per 1000 hours compared with Apprentices (p≤0.025). Further, intraseason differences were observed in medical attention, but not time-loss, injury incidence rates with the highest incidence rates in early (August and September) and late (June) season months. Thirty-five per cent of time-loss injuries resulted in over 28 days of modified dance training. A greater percentage of time-loss injuries were classified as overuse (women: 50%; men: 51%) compared with traumatic (women: 40%; men: 41%).
This is the first study to report the incidence rate of medical attention and time-loss injuries in professional ballet dancers. Incidence rates differed across company ranks and months, which may inform targeted injury prevention strategies.
描述一家专业芭蕾舞公司连续五个赛季医疗关注度和伤停时间损失的发生率、严重程度、负担和病因。
在 2015/2016 年至 2019/2020 年赛季期间，前瞻性地记录了 123 名职业芭蕾舞演员（女性：n=66，年龄：28.0±8.3 岁；男性：n=57，年龄：27.9±8.5 岁）的医疗关注度损伤、伤停时间损失和舞蹈曝光时间。
女性医疗关注度损伤的发生率（每 1000 小时）为 3.9（95%CI 3.3 至 4.4），男性为 3.1（95%CI 2.6 至 3.5）。女性伤停时间损失的发生率（每 1000 小时）为 1.2（95%CI 1.0 至 1.5），男性为 1.1（95%CI 0.9 至 1.3）。首席独舞演员和首席演员每 1000 小时比学徒多经历 2.0-2.2 次医疗关注度损伤和 0.9-1.1 次伤停时间损失（p≤0.025）。此外，还观察到了医疗关注度的季节内差异，但伤停时间损失的发生率没有季节内差异，发病率最高的月份是赛季早期（8 月和 9 月）和晚期（6 月）。35%的伤停时间损失导致超过 28 天的舞蹈训练调整。与创伤性损伤（女性：40%；男性：41%）相比，更多的伤停时间损失被归类为过度使用（女性：50%；男性：51%）。
这是第一项报告专业芭蕾舞演员医疗关注度和伤停时间损失发生率的研究。发生率因公司级别和月份而异，这可能为有针对性的损伤预防策略提供信息。
