高强度运动对大学水平碰撞和竞技运动运动员颈椎测量、前庭/眼运动筛查和前庭–眼反射功能的影响

Effect of High-Intensity Exercise on Measures of Cervical Spine, Vestibular/Ocular-Motor Screening, and Vestibulo-Ocular Reflex Func-tion in University Level Collision and Com-bative Sport Athletes

摘要: 目的：检查高强度体力消耗如何影响颈椎(CSp)、前庭/眼球运动屏幕(VOMS)和前庭眼球反射(VOR)功能的临床测量。方法：病例系列。设置：运动医学中心参与者：共有111名男性运动员同意参加(66名橄榄球运动员，45名摔跤运动员；中位年龄 = 17岁[范围16~19]岁)。主要结果测量：结果测量包括CSp测试(颈屈肌耐力、头部扰动测试、颈屈曲旋转测试和前外侧强度)、VOR (头部推力测试和动态视力[DVA])，以及VOMS的量化版本。在完成30-15间断体能测试之前和之后评估这些指标。使用Bland-Altman图和Wilcoxon符号秩检验分析数据，使用p < 0.004。结果：左侧用力后颈椎前外侧强度(kg)降低(z = 3.87; p < 0.001)，但不在条件之间的右侧(z = −1.49; p = 0.14)。运动员报告头晕增加(z = −3.55; p = 0.004)，运动后DVA减少(z = −2.78; p < 0.001)。运动后所有其他指标没有显着差异(p > 0.011)。结论：DVA表现降低，左前外侧力量降低，头晕加重。发生在大学碰撞和好斗运动员的高强度运动后，这对与运动相关的脑震荡的边线筛查有影响。

Abstract: Objectives: To examine how high-intensity physical exertion affects clinical measures of cervical spine (CSp), vestibular/ocular motor screen (VOMS), and vestibulo-ocular reflex (VOR) function. Method: Case series. Setting: Sports Medicine Centre. Participants: A total of 111 athletes consented to participate (66 rugby, 45 wrestling; median age = 17 years [range 16~19 years]). Main Outcome Measures: Outcome measures included tests of CSp (cervical flexor endurance, head perturbation test, cervical flexion rotation test and anterolateral strength), VOR (head thrust test and dynamic visual acuity [DVA]), and a quantified version of the VOMS. These metrics were assessed prior to and after completing the 30-15 Intermittent Fitness Test. Bland-Altman plots and Wilcoxon signed-rank tests were utilized to analyze the data using an alpha of p < 0.004. Results: Cervical anterolateral strength (kg) was reduced post-exertion on the left (z = 3.87; p < 0.001), but not on the right be-tween conditions (z = −1.49; p = 0.14). Athletes reported increased dizziness (z = −3.55; p = 0.004) and had reduced DVA following exertion (z = −2.78; p < 0.001). All other metrics were not signifi-cantly different following exertion (p > 0.011). Conclusion: Reduced performance on DVA, decreased left-anterolateral strength, and increased dizziness occurred following high-intensity exertion in varsity collision and combative athletes, which has implications for sideline screening for sport-related concussion.
