This study examines the incidence of ankle injuries and identifies ankle injury risk among contemporary preprofessional dancers.
A total of 91 first-year contemporary preprofessional dancers were prospectively followed during one academic year. Self-reported ankle injuries, assessed with the Oslo Sports Trauma Research Centre questionnaire, were categorised as all complaint ankle injuries, substantial ankle injuries or time-loss ankle injuries. In addition, ankle injuries leading to medical attention were included. Regression analyses were used to determine the association between potential risk factors (dancer characteristics, history of ankle injury in the previous year, ankle range of motion and dorsiflexion) and ankle injuries.
The 1-year ankle injury incidence proportion was 18.7% (n=17), 8.8% (n=8), 15.4% (n=14) and 7.7% (n=7), respectively, for all complaint ankle injuries, ankle injuries requiring medical attention, time-loss injuries and substantial injuries. Being male (OR=0.27; 95% CI 0.09 to 0.75) and being a student of the Bachelors in Dance and Education (OR=0.27; 95% CI 0.08 to 0.97) were univariately associated with a lower risk of an ankle injury.
Almost 20% of first-year preprofessional dancers reported an ankle injury, with more than 80% of the dancers reporting that their injury leads to dance time loss. Males and students of the bachelors in dance and education were at lower risk of ankle injuries. As ankle injuries are common among dancers, studies with larger sample sizes, a more heterogeneous population (eg, different dance styles) and longer follow-up periods are necessary to evaluate the impact of ankle injuries in further detail.
本研究调查当代职业前舞者踝关节损伤的发生率，并确定踝关节损伤风险。
在一个学年内对91名一年级当代职业前舞者进行前瞻性跟踪研究。采用奥斯陆运动创伤研究中心问卷评估自我报告的踝关节损伤情况，将其分为所有主诉踝关节损伤、严重踝关节损伤或导致停训的踝关节损伤。此外，纳入需要就医的踝关节损伤。采用回归分析确定潜在风险因素（舞者特征、上一年踝关节损伤史、踝关节活动范围和背屈）与踝关节损伤之间的关联。
所有主诉踝关节损伤、需要就医的踝关节损伤、导致停训的损伤和严重损伤的1年踝关节损伤发生率分别为18.7%（n = 17）、8.8%（n = 8）、15.4%（n = 14）和7.7%（n = 7）。男性（OR = 0.27；95%CI 0.09至0.75）以及舞蹈与教育专业本科学生（OR = 0.27；95%CI 0.08至0.97）单因素分析显示踝关节损伤风险较低。
近20%的一年级职业前舞者报告有踝关节损伤，超过80%的舞者表示其损伤导致舞蹈训练时间损失。男性以及舞蹈与教育专业本科学生踝关节损伤风险较低。由于踝关节损伤在舞者中很常见，因此需要更大样本量、更具异质性人群（如不同舞蹈风格）以及更长随访期的研究，以更详细地评估踝关节损伤的影响。
