This study aimed to investigate the effects of sleep deprivation on postural control, subjective fatigue assessment and psychomotor performance, and to assess the efficiency of an objective posturographic test as an indicator of mental fatigue. Postural sway using static posturography (Romberg's test), subjective fatigue assessment (Stanford Sleepiness Scale) and psychomotor performance (Sternberg dual-task test) were assessed in 12 subjects before and after 24 h of sustained wakefulness. After sustained wakefulness, the Romberg test parameters of circumference area and rectangle area with the eyes-closed, and standard deviation in the anterior-posterior direction with the eyes-open were significantly higher compared with baseline values (before sustained wakefulness). Subjective fatigue assessment scores were also significantly increased, while psychomotor performance was unchanged. Sleep deprivation can arouse a feeling of fatigue and can affect postural stability, hence an objective posturographic test score may be useful as an indicator of mental fatigue.
本研究旨在调查睡眠剥夺对姿势控制、主观疲劳评估和精神运动表现的影响，并评估客观姿势描记测试作为精神疲劳指标的有效性。在12名受试者持续清醒24小时前后，使用静态姿势描记法（罗姆伯格试验）评估姿势摆动、主观疲劳评估（斯坦福嗜睡量表）和精神运动表现（斯特恩伯格双任务测试）。持续清醒后，闭眼时周长面积和矩形面积的罗姆伯格测试参数以及睁眼时前后方向的标准差与基线值（持续清醒前）相比显著更高。主观疲劳评估得分也显著增加，而精神运动表现未改变。睡眠剥夺会引起疲劳感并影响姿势稳定性，因此客观姿势描记测试分数可能作为精神疲劳的指标有用。
