To characterize clinical burden of injuries incurred by circus students enrolled in a 3-year college training program.
Student (n=334) injury data derived from an in situ clinic was examined over a 7.5-year time frame from August 2009 to December 2016. Injury incidence rate (per 1,000 training hours) was calculated and clinical incidence (injuries/year) was examined in relation to year in program, sex, age, and circus discipline. Weekly and monthly injury incidence were plotted with respect to milestones in the scholastic training year. Clinical burden (injury incidence and duration) was examined according to anatomic location and circus discipline.
The overall injury incidence rate was 1.89 injuries/1,000 training hours and 0.94 injuries/1,000 training hours for injuries with a duration longer than 4 weeks. Clinical incidence decreased with year in program (p<0.05) and there were no sex or age differences. Temporal analysis demonstrated elevated weekly injury incidence for the 3 weeks following return from both summer and winter vacation (p<0.01) and for the weeks leading up to technical exams (p<0.01). According to anatomical location, shoulder injuries accounted for the greatest clinic burden followed by ankles and according to discipline, ground acrobat flyers followed by ground acrobats with equipment accounted for the greatest clinic burden.
Overall injury incidence rate in the circus training program was within the range reported by other circus training programs and similar artistic and athletic training programs. Resources should be designated for enhanced rehabilitation efficacy and prevention of shoulder and ankle injuries and for ground acrobats with equipment and flyers. Preventative strategies to improve safety upon return-to-training after vacations should be examined.
描述参加为期 3 年大学培训计划的马戏团学生所受伤害的临床负担。
从 2009 年 8 月至 2016 年 12 月的 7.5 年时间内，检查了来自现场诊所的学生（n=334）伤害数据。计算了每 1000 小时训练的受伤发生率（每 1000 小时训练的受伤发生率），并检查了与项目年限、性别、年龄和马戏团学科相关的临床发生率（受伤/年）。根据学年的里程碑，绘制了每周和每月的受伤发生率。根据解剖部位和马戏团学科检查了临床负担（受伤发生率和持续时间）。
总体受伤发生率为每 1000 小时训练 1.89 次受伤和每 1000 小时训练 0.94 次受伤，受伤持续时间超过 4 周。临床发病率随着项目年限的增加而降低（p<0.05），性别和年龄无差异。时间分析表明，夏季和冬季假期后返回后的 3 周内每周的受伤发生率升高（p<0.01），技术考试前的几周内升高（p<0.01）。根据解剖部位，肩部受伤占最大的临床负担，其次是踝关节，根据学科，地面杂技飞人紧随其后的是有装备的地面杂技演员。
马戏团培训计划中的总体受伤发生率在其他马戏团培训计划以及类似的艺术和运动训练计划报告的范围内。应指定资源，以提高康复效果，预防肩部和踝关节受伤，以及有装备的地面杂技演员和飞人。应研究改善假期后重返训练时安全性的预防策略。
