Physical fatigue is a painful phenomenon which is localised in overstressed muscles. Mental fatigue is a diffuse sensation of weariness; it is a functional state, one of several intermediate conditions between the two extremes of alarm and sleep. A neurophysiological model of fatigue, involving an activating and inhibitory system has been developed. Fatigue in industrial practice has clinical s...

BACKGROUND Fibromyalgia (FM) affects approximately 1-3 % of the general population. Fatigue limits the work ability and social life of patients with FM. A few studies of physical exercise have included measures of fatigue in FM, indicating that exercise can decrease fatigue levels. There is limited knowledge about the effects of resistance exercise on multiple dimensions of fatigue in FM. The p...

AIMS To study associations between characteristics of employees active at work and making a fatigue related visit to the general practitioner (GP) or occupational physician (OP) in terms of fatigue, physical health problems, mental health problems, psychosocial work characteristics, and attributions of their fatigue complaints. METHODS Self report questionnaires from the Maastricht Cohort Stu...

OBJECTIVE To provide a multidimensional characterization of fatigue in patients with multiple sclerosis (MS). DESIGN Cross-sectional design. Fifty patients with clinically definite MS were compared on the dimensions of fatigue with 51 patients with chronic fatigue syndrome (CFS) and 53 healthy subjects. RESULTS Fourty-six percent of the patients with MS reported fatigue to be present at lea...

BACKGROUND As a symptom of multiple sclerosis (MS), fatigue is difficult to manage because of its unknown etiology, the lack of efficacy of the drugs tested to date and the absence of consensus about which would be the ideal measure to assess fatigue. OBJECTIVE Our aim was to assess the frequency of fatigue in a sample of MS patients and healthy controls (HC) using two fatigue scales, the Fat...

background:   the  role of nutrition  in the  progression  of multiple  sclerosis (ms) and  related  complications  such  as fatigue  has been  reported by several studies.  the  aim of this  study  is the  assessment of nutritional  status  and  its relationship with fatigue in multiple sclerosis patients. methods:  this  is  a  cross-sectional study, in which  101 relapsing-remitting ms patie...

The present study attempt to investigate the changes of the electroencephalogram (EEG) rhythms due to physical fatigue. Three different methods to enhance EEG signals have been applied. Aside from the Referential method, the Common Average Reference method as well as the Current Source Density method has been applied to the raw data prior to processing. Ten subjects participated in this study. ...

The available learning and forgetting models do not consider the physical loading that performing a task requires. In some situations, physical loading results in workers’ fatigue on the job that is followed by rest breaks to alleviate it. The aim of this paper is to present the "learningforgetting-fatigue-recovery model" (LFFRM) that addresses possible issues relating to workers’ capabilities ...
