Different fatigue measurements and their relation to saccadic functions were investigated in 15 patients with a mild traumatic brain injury (mTBI) and 15 orthopedic controls.
MATERIALS & METHODS: State fatigue was measured with the Fatigue Severity Scale and trait fatigue with the question on fatigue in the Rivermead Post Concussion Questionnaire and fatigability as decreased performance over time on a neuropsychological measure.
Patients with an mTBI scored significantly higher in state fatigue and showed more fatigability compared with the orthopedic controls. Among patients with mTBI, state fatigue correlated with prosaccade latency and cognitive fatigability, while trait fatigue correlated with anxiety and antisaccade latency and variability.
This pilot study indicates that saccade measurements might, in the future, be useful in the understanding of fatigue and in the search for prognostic factors after mTBI.
在15例轻度创伤性脑损伤（mTBI）患者和15例骨科对照者中，研究不同的疲劳测量方法及其与扫视功能的关系。
用疲劳严重程度量表测量状态疲劳，用Rivermead脑震荡后问卷中的疲劳问题测量特质疲劳，并通过神经心理学测量中随时间推移表现下降来测量易疲劳性。
与骨科对照者相比，mTBI患者的状态疲劳得分显著更高，且表现出更多的易疲劳性。在mTBI患者中，状态疲劳与顺向扫视潜伏期和认知易疲劳性相关，而特质疲劳与焦虑、反向扫视潜伏期和变异性相关。
这项初步研究表明，未来扫视测量可能有助于理解mTBI后的疲劳情况并寻找预后因素。
