ABSTRACT
<p><b>OBJECTIVE</b>To assess mental fatigue by noninvasive monitoring of the physiological signals.</p><p><b>METHODS</b>The changes in the physiological parameters including the electrodermal activity, heart rate and heart rate variability were analyzed in 14 subjects performing the reaction-time tasks when fatigue and changes in the reaction time occurred.</p><p><b>RESULTS</b>The average skin conductance level, average heart rate, and heart rate variability parameters including the total power density, percentage of the very low power density, percentage of high power density all differed significantly between the sober state and the mental fatigue state.</p><p><b>CONCLUSION</b>Monitoring the physiological parameters including the electrodermal activity, heart rate and heart rate variability is a noninvasive, effective and practical approach to mental fatigue assessment.</p>
