Fatigue and Cognitive Fatigability in Mild Traumatic Brain Injury are Correlated with Altered Neural Activity during Vigilance Test Performance

摘要

Figure 1. Boxplots of Visual Analog Scale of Fatigue (VAS-f) ratings before and after psychomotor vigilance task (PVT) for patients and controls, respectively. The mild traumatic brain injury patients reported significantly more self-rated current fatigue (VAS-f) than the healthy controls after the PVT (p < 0.01) according to Mann–Whitney U test.
