background: the present study aimed to investigate the effects of work shifts and mental workload on chronic fatigue among female nurses in intensive care units of selected hospitals in shiraz. methods: the participants in this cross-sectional study were 118 female nurses working in intensive care units of three hospitals in shiraz with an average age of 304.8± years. sp (samn-perelli) mental...
original article mental fatigue (mf) is considered as a contributor factor in incident, even catastrophic one. electroencephalography measurement has been the most acceptable method to assess mf by neurologists. however, this method could be hardly feasible in real work setting. flicker fusion device, by contrast, is more usable at work setting. the purpose of this study was to compare the cr...
Background: Fatigue in the workers reduces the individual's resistance and eventually leads to the lower performance, increased errors and accidents. This study assessed the fatigue, mental workload and the correlation between them, in operating room personnel of Hamadan hospitals, Iran. Materials and Methods: In a descriptive study, the mental workload and its association with fatigue in oper...
Background and Objective: Mental fatigue usually occurrs as a result of long-term cognitive activities. Mental fatigue could have important effects on the daily lives of healthy people. Therefore, the purpose of this study was to estimate mental fatigue and its impact on staff performance. Materials and Methods: This descriptive analytic study was performed on 10 staff with a mean age of 36±6....
Fatigue is a very common non-motor symptom in Parkinson disease (PD) patients. It included physical fatigue and mental fatigue. The potential mechanisms of mental fatigue involving serotonergic dysfunction and abnormal iron metabolism are still unknown. Therefore, we evaluated the fatigue symptoms, classified PD patients into fatigue group and non-fatigue group, and detected the levels of serot...
Background and aims: In accomplishing attention-consuming tasks, mental fatigue reduces productivity and increases error rate as the factors involved in work accidents. The present research goal was to study the effects of sleep quality and mental fatigue on attention and reaction time in the thermal comfort condition. Methods: This experimental research was conducted on 33 university students...
background: multiple sclerosis (ms) is a neurological disease with fatigue as most prevalent symptom. psychopathological symptoms, physical and mental dysfunctions and body mass abnormalities potentially could deteriorate fatigue. thus, in this study, we aimed at evaluating the effect of these factors on fatigue severity of ms patients. methods: in this cross-sectional study, 162 patients with ...
The objective was to study changes in EEG time-domain Kolmogorov complexity under different mental fatigue state and to evaluate mental fatigue using Lempel-Ziv complexity analysis of spontaneous EEG in healthy human subjects. EEG data for healthy subjects were acquired using a net of 2 electrodes (Fp1 and Fp2) at PM 4:00, AM 12:00 and AM 3:00 in the 24 hours sleep-deprived mental fatigue exper...
The effects of long term mental arithmetic task on psychology are investigated by subjective self-reporting measures and action performance test. Based on electroencephalogram (EEG) and heart rate variability (HRV), the impacts of prolonged cognitive activity on central nervous system and autonomic nervous system are observed and analyzed. Wavelet packet parameters of EEG and power spectral ind...
