The impacts of prolonged visual display terminal (VDT) work on central nervous system and autonomic nervous system are observed and analyzed based on electroencephalogram (EEG) and heart rate variability (HRV). Power spectral indices of HRV, the P300 components based on visual oddball task, and multichannel linear descriptors of EEG are combined to estimate the change of mental fatigue. The res...

The aim of this study was to investigate the effects of mental fatigue on the duration of actual and imagined goal-directed arm movements involving speed-accuracy trade-off. Ten participants performed actual and imagined point-to-point arm movements as accurately and as fast as possible, before and after a 90-min sustained cognitive task inducing mental fatigue, and before and after viewing a n...

this paper reviews the current literature examining the pervasive symptom of fatigue experienced in three of the most common degenerative neurological conditions: multiple sclerosis (ms), parkinson’s disease (pd) and post-polio syndrome (pps). the existing literature can be considered under four headings definition and prevalence, type, cause, impact of fatigue. fatigue is a common symptom in d...

Fatigue increases the tendency of poor train driving strategy decision. Decision making in cognitive overload and underload situation mostly outputs bad decisions. Accordingly, driver’s function is required to be sTable during travel so that they can give correct response at a given situation. This study constructs conceptual framework for workload management (CWM) driver by taking energy expen...

BACKGROUND Fatigue is usually reported after lack of sleep or excessive physical or mental effort. Endocrine disorders are also associated with the symptoms of fatigue. Symptoms of fatigue were reported 20% of working population. Anesthesiologists are more exposed to stress at work because of long working hours and high demand of the job. The aim of this study was to evaluate fatigue at work fr...

We propose a driver fatigue recognition model based on the dynamic Bayesian network, information fusion and multiple contextual and physiological features. We include features such as the contact physiological features (e.g., ECG and EEG), and apply the first-order Hidden Markov Model to compute the dynamics of the Bayesian network at different time slices. The experimental validation shows the...

Several studies suggest that when subjects mentally rehearse or execute a familiar action, they engage similar neural and cognitive operations. Here, we examined whether muscle fatigue could influence mental movements. Participants mentally and actually performed a sequence of vertical arm movements (rotation around the shoulder joint) before and after a fatiguing exercise involving the right a...
