Capturing baseline data before a concussion can be a valuable tool in individualized care. However, not all athletes, including dancers, have access to baseline testing. When baseline examinations were not performed, clinicians consult normative values. Dancers are unique athletes; therefore, describing values specific to dancers may assist those working with these athletes in making more informed decisions.
To describe values for key concussion measures of dancers. Our secondary aim was to examine whether differences existed between sexes and professional status. Finally, we explored factors that may affect dancers' scores.
Cross-sectional study.
Professional dance companies and a collegiate dance conservatory.
A total of 238 dancers (university = 153, professional = 85; women = 171; men = 67; age = 21.1 ± 4.8 years).
MAIN OUTCOME MEASURE(S): We calculated the total symptom severity from the Sport Concussion Assessment Tool-3rd edition; the Standardized Assessment of Concussion score; the modified Balance Error Scoring System score; and the King-Devick score for each participant. Group differences were analyzed with Mann-Whitney or t tests, depending on the data distribution. We used bivariate correlations to explore the effects of other potential influencing factors.
Participants demonstrated the following baseline outcomes: symptom severity = 16.6 ± 12.8; Standardized Assessment of Concussion = 27.5 ± 1.8; modified Balance Error Scoring System = 3.2 ± 3.1 errors; and King-Devick = 41.5 ± 8.2 seconds. A Mann-Whitney test revealed differences in King-Devick scores between female (40.8 ± 8.0 seconds) and male (43.4 ± 8.4 seconds) dancers ( P = .04). An independent-samples t test also demonstrated a difference in modified Balance Error Scoring System scores between female (2.95 ± 3.1 errors) and male (3.8 ± 3.1 errors) dancers ( P = .02). Age, hours of sleep, height, and history of concussion, depression, or injury did not display moderate or strong associations with any of the outcome measures.
Dancers' symptom severity scores appeared to be higher than the values reported for other athletes. Additional studies are needed to establish normative values and develop a model for predicting baseline scores.
在脑震荡前获取基线数据可以成为个性化护理的有价值工具。然而，并非所有运动员，包括舞者，都可以进行基线测试。当未进行基线检查时，临床医生会参考正常值。舞者是独特的运动员；因此，描述特定于舞者的值可能有助于那些与这些运动员合作的人做出更明智的决策。
描述舞者的关键脑震荡测量值的数值。我们的次要目的是检查性别和专业地位之间是否存在差异。最后，我们探讨了可能影响舞者分数的因素。
横断面研究。
专业舞蹈公司和大学舞蹈学院。
共有 238 名舞者（大学=153 名，专业=85 名；女性=171 名，男性=67 名；年龄=21.1±4.8 岁）。
我们从第 3 版运动性脑震荡评估工具中计算了总症状严重程度；标准脑震荡评估得分；改良平衡错误评分系统得分；以及每位参与者的 King-Devick 得分。根据数据分布，使用 Mann-Whitney 或 t 检验分析组间差异。我们使用双变量相关性来探讨其他潜在影响因素的影响。
参与者的基线结果如下：症状严重程度=16.6±12.8；标准脑震荡评估得分=27.5±1.8；改良平衡错误评分系统得分=3.2±3.1 错误；King-Devick 得分=41.5±8.2 秒。Mann-Whitney 检验显示，女性（40.8±8.0 秒）和男性（43.4±8.4 秒）舞者的 King-Devick 得分存在差异（P=.04）。独立样本 t 检验还显示，女性（2.95±3.1 错误）和男性（3.8±3.1 错误）舞者的改良平衡错误评分系统得分存在差异（P=.02）。年龄、睡眠时间、身高以及脑震荡、抑郁或受伤史与任何结果测量指标均无中度或高度关联。
舞者的症状严重程度评分似乎高于其他运动员报告的值。需要进一步的研究来建立正常值并开发预测基线评分的模型。
