Sports-related concussions are prevalent in the United States. Various diagnostic tools are utilized in order to monitor deviations from baseline in memory, reaction time, symptoms, and balance. Evidence indicates that dehydration may also alter the results of diagnostic tests.
The purpose was to determine the effect of exercise-induced dehydration on performance related to concussion examination tools.
Repeated measures design.
Seventeen recreationally competitive, non-concussed participants (age: 23.1±3.1 years, height:168.93±10.71 cm, mass: 66.16 ± 6.91 kg) performed three thermoneutral, counterbalanced sessions (rested control, euhydrated, dehydrated). Participants were either restricted (0.0 L/hr) or provided fluids (1.0 L/hr) while treadmill running for 60 min at an intensity equal to 65-70% age-predicted maximum heart rate (APMHR). The Sport Concussion Assessment Tool 3 (SCAT3) was utilized to assess symptoms, memory, balance, and coordination.
Statistically significant differences were seen among sessions for symptom severity and symptom total. The rested control session had significantly lower values when compared to the dehydrated session. Additionally, the symptom total in the rested control was significantly lower than the euhydrated condition as well. No statistically significant differences were seen for the BESS or memory scores.
Mild exercise-induced dehydration results in increased self-reported symptoms associated with concussions. Clinicians tasked with monitoring and accurately diagnosing head trauma should take factors such as hydration status into account when assessing patients for concussion with the SCAT3. Clinicians should proceed with caution and not assume concussion as primary cause for symptom change.

与运动相关的脑震荡在美国很普遍。人们使用各种诊断工具来监测记忆、反应时间、症状和平衡方面相对于基线的偏差。有证据表明，脱水也可能改变诊断测试的结果。
目的：本研究旨在确定运动引起的脱水对与脑震荡检查工具相关的表现的影响。研究设计：重复测量设计。方法：17名具有娱乐竞技水平、未受过脑震荡的参与者（年龄：23.1±3.1岁，身高：168.93±10.71厘米，体重：66.16±6.91千克）进行了三个温度中性、平衡的实验环节（静息对照、水合正常、脱水）。参与者在跑步机上以相当于65 - 70%年龄预测最大心率（APMHR）的强度跑步60分钟时，要么被限制饮水（0.0升/小时），要么补充液体（1.0升/小时）。使用运动脑震荡评估工具3（SCAT3）来评估症状、记忆、平衡和协调能力。结果：各实验环节在症状严重程度和症状总分上存在统计学显著差异。与脱水环节相比，静息对照环节的值显著更低。此外，静息对照环节的症状总分也显著低于水合正常状态。在BESS或记忆分数方面未观察到统计学显著差异。结论：轻度运动引起的脱水会导致与脑震荡相关的自我报告症状增加。负责监测和准确诊断头部创伤的临床医生在使用SCAT3评估脑震荡患者时应考虑水合状态等因素。临床医生应谨慎行事，不要将症状变化的主要原因假定为脑震荡。证据水平：3级。
