We analysed work-related musculoskeletal injuries (WMSI) in two modern dance companies to determine whether injury rates decreased and patterns altered compared to previous 3-yr and 6-yr audits (0.48 and 0.25/1000-hrs exposure respectively). In this prospectively designed 15-yr cohort study, data were collected in 30-dancer Company-1 and 12-dancer Company-2. In-house physical therapists tracked WMSI and time-loss-injuries for 159 dancers (42 dancers/yr). 15-yrs were grouped into five 3-yr blocks for comparison with prior audits. Negative binomial logistic regression analyses were conducted with exposure-hrs converted to the natural log and used as the offset variable. Block and company were categorical predictors for dependent variables: WMSI, time-loss-injuries, trauma-injuries and overuse-injuries (p < 0.05). 69% of dancers reported WMSI; 45% sustained at least one time-loss-injury. Company-1, with greater annual exposure, was 1.6-times more likely to sustain time-loss-injuries (p = 0.016, CI = 1.095-2.422) and 5.6-times more likely to sustain time-loss overuse-injuries (p = 0.003, CI = 1.812-17.327). Compared to Block-1, WMSI and time-loss-injuries decreased in Blocks-2, 3, and 5 (p ≤ 0.027). The ratio of time-loss overuse to trauma-injuries was reversed, with trauma-injuries accounting for over 80% of injuries by Block 5. Time-loss-injuries averaged 0.16 injuries/1000-hrs, lower than rates in ballet and sports. Decreased injury rates and changed injury patterns demonstrate efficacious injury management and prevention programming.
我们分析了两家现代舞蹈公司与工作相关的肌肉骨骼损伤（WMSI），以确定与之前的 3 年和 6 年审计（分别为 0.48 和 0.25/1000 小时暴露率）相比，受伤率是否降低以及模式是否发生变化。在这项前瞻性设计的 15 年队列研究中，数据收集于 30 名舞者的公司 1 和 12 名舞者的公司 2。内部物理治疗师跟踪了 159 名舞者（每年 42 名舞者）的 WMSI 和因伤损失的工作时间。15 年被分为五个 3 年组，与之前的审计进行比较。使用暴露小时数转换为自然对数并用作偏移变量的负二项逻辑回归分析进行分析。块和公司是因变量（WMSI、因伤损失的工作时间、创伤性损伤和过度使用性损伤）的分类预测因子（p<0.05）。69%的舞者报告有 WMSI；45%至少有一次因伤损失的工作时间。公司 1 的年暴露量较大，因伤损失的工作时间受伤的可能性是公司 2 的 1.6 倍（p=0.016，CI=1.095-2.422），因伤损失过度使用受伤的可能性是公司 2 的 5.6 倍（p=0.003，CI=1.812-17.327）。与第 1 块相比，第 2、3 和 5 块的 WMSI 和因伤损失的工作时间减少（p≤0.027）。因伤损失过度使用与创伤性损伤的比例发生逆转，到第 5 块时，创伤性损伤占损伤的 80%以上。因伤损失的工作时间平均为 0.16 次/1000 小时，低于芭蕾舞和运动的受伤率。受伤率的降低和受伤模式的变化表明，受伤管理和预防计划是有效的。
