Ballet dancers are thought to be at higher risk of lower extremity injury. This objective of this study was to describe the self-reported incidence, location, and factors associated with lower extremity injury in collegiate ballet dancers. Two hundred and forty-nine female ballet dancers responded to a questionnaire that addressed their injury event/location, dance behavior over the past 2 years, and overall dance history. Behaviors assessed included the following: types and number of shoes worn (pointé shoes/ballet slippers), wear time, training time (session frequency and duration), use of warm-up/cool-down, and use of a strengthening program and lower extremity accessory. Overall dance history included age of the onset of training, total years of experience, and number of dance styles. Backward multivariable logistic regression analysis was used to determine the extent to which variables measured were associated with injury. Ankle injury was the most prevalent injury. Years of wearing pointé shoes (adjusted odds ratio = 1.21, = 0.01) and days/weeks in pointé shoes (adjusted odds ratio = 1.26, = 0.04) were associated with an increased risk of injury; while additional strengthening (adjusted odds ratio = 0.39, = 0.02) and use of lower extremity accessories during classes/rehearsals (adjusted odds ratio = 0.64, = 0.01) were protective associations. These findings suggested that the use of pointé shoes, lower extremity accessories, and additional exercise should specifically be recorded during evaluation of injured ballet dancers; and must be considered potential factors to modify during rehabilitation.
芭蕾舞舞者被认为下肢受伤风险更高。本研究的目的是描述大学芭蕾舞舞者自我报告的下肢受伤发生率、受伤部位以及与下肢受伤相关的因素。249名女性芭蕾舞舞者对一份问卷做出了回应，问卷涉及她们的受伤事件/部位、过去两年的舞蹈行为以及总体舞蹈经历。评估的行为包括：所穿鞋子的类型和数量（足尖鞋/芭蕾舞软鞋）、穿着时间、训练时间（课程频率和时长）、是否进行热身/放松活动、是否采用强化训练计划以及是否使用下肢辅助装备。总体舞蹈经历包括开始训练的年龄、总经验年限以及舞蹈风格数量。采用向后多变量逻辑回归分析来确定所测量的变量与受伤之间的关联程度。脚踝受伤是最常见的损伤。穿着足尖鞋的年限（调整后的优势比 = 1.21，P = 0.01）以及穿着足尖鞋的天数/周数（调整后的优势比 = 1.26，P = 0.04）与受伤风险增加相关；而额外的强化训练（调整后的优势比 = 0.39，P = 0.02）以及在课堂/排练期间使用下肢辅助装备（调整后的优势比 = 0.64，P = 0.01）具有保护作用。这些发现表明，在评估受伤的芭蕾舞舞者时，应特别记录足尖鞋的使用情况、下肢辅助装备的使用情况以及额外的锻炼情况；并且在康复过程中必须将这些因素视为可能需要调整的潜在因素。
