Dancers may compensate alignment at the spine, hip, knees, ankles, and feet to achieve a greater turnout than is available at the hip alone. Such compensations are believed to lead to many of the musculoskeletal injuries experienced by dancers, especially overuse injuries. The aim of this study was to explore the relationship between compensated turnout and injury of the lower extremities and low back. Twenty-two university level modern dancers age 19 to 23 participated. Measurements were taken of active hip external rotation (AHER) prone and functional turnout (FTO) in first position. The difference between FTO and AHER was designated as compensated turnout (CTO). A questionnaire was conducted to gather information about dancers' injuries within the past 2 years. A total of 17 participants (77%) reported experiencing at least one injury in the 24 month period. All dancers compensated turnout. Results revealed a large variability in CTO among participants, ranging from 3° to 72°. Statistical analysis showed a significant relationship (r = 0.45, N = 22, p = 0.04) between CTO and the number of injuries experienced, especially as related to low back pain (r = 0.50, N = 22, p = 0.02). Students with no injury had a CTO mean of 26°, while those with two or more injuries had a CTO mean of 43°. Results contribute to previous studies that have examined the effects of CTO in ballet dancers and further indicate that compensatory patterns of turnout may increase the risk of experiencing more than one injury in university level modern dancers.
舞者可能会通过调整脊柱、髋部、膝盖、脚踝和足部的排列来获得比仅靠髋部更大的外旋幅度。据信，这种代偿会导致舞者出现许多肌肉骨骼损伤，尤其是过度使用损伤。本研究的目的是探讨代偿性外旋与下肢和下背部损伤之间的关系。22名年龄在19至23岁的大学水平现代舞者参与了研究。测量了俯卧位时的主动髋部外旋（AHER）和一位时的功能性外旋（FTO）。FTO与AHER之间的差异被定义为代偿性外旋（CTO）。通过问卷调查收集了舞者在过去两年内的受伤信息。共有17名参与者（77%）报告在24个月内至少经历过一次损伤。所有舞者都存在代偿性外旋。结果显示，参与者之间的CTO差异很大，范围从3°到72°。统计分析表明，CTO与受伤次数之间存在显著关系（r = 0.45，N = 22，p = 0.04），尤其是与下背部疼痛相关（r = 0.50，N = 22，p = 0.02）。未受伤的学生CTO平均值为26°，而有两次或更多次受伤的学生CTO平均值为43°。这些结果为之前研究CTO对芭蕾舞者影响的研究提供了补充，并进一步表明，在大学水平的现代舞者中，外旋的代偿模式可能会增加遭受不止一次损伤的风险。
