The objective of this study was to describe sleep patterns in patients with heart failure (HF) and analyze associations between sleep and the following variables: gender, age, fatigue, fatigue on exertion, physical activity, functional class, drug therapy, dyspnea, and body mass index. The nonprobability sample consisted of 400 patients (mean age 57.8 years; 64.8% were men, average schooling of...

The purpose of this study was to determine the effect of functional limitations and fatigue on the quality of life (QoL) in people with multiple sclerosis (MS). A descriptive case series study at Lagoa Hospital - Rio de Janeiro, Brazil was carried. The main outcome measurements were demographic variables, QoL (SF-36 v.1), disability (EDSS), motor function of the upper limb (Box & Blocks test), ...

INTRODUCTION The aim of this study was to examine the relationship between serum C-terminal agrin fragment (CAF) concentrations and neuromuscular fatigue in older adults. METHODS Twenty-two healthy older men and women volunteered for this study. Resting fasted blood samples were collected and prepared for measurement of serum CAF concentration by a commercially available ELISA kit. The onset ...

Controvery exists as to how fatigue can influence lifting biomechanics. Lifters have decreased their range of motion (ROM) at the hip and knee [1] and increased their flexion ROM at the trunk [2], while other lifters have responded oppositely, where hip ROM was increased and trunk ROM decreased concurrent with a decrease in moment loading on the spine, as a function of time [3]. It remains clea...

Accurate assessment of mental fatigue level would improve operational safety and efficacy of astronauts for long-term space flight. Identification of neurophysiological markers can index impending overload or fatigue before performance decrements using neuroimaging technologies. The current study utilized functional near-infrared spectroscopy (fNIR) to investigate the relationship of hemodynami...

OBJECTIVES To gain an improved understanding of fatigue in Parkinson disease (PD) by exploring possible predictors among a wide range of motor and non-motor aspects of PD. METHODS 118 consecutive PD patients (54% men; mean age 64 years) were assessed regarding fatigue, demographics and a range of non-motor and motor symptoms. Variables significantly associated with fatigue scores in bivariate...

BACKGROUND AND PURPOSE Fatigue is a common symptom in amyotrophic lateral sclerosis (ALS). Although sleep disturbances are a candidate factor that may interfere with fatigue in patients with ALS, the role of sleep-related abnormalities in determining fatigue in ALS is unknown. OBJECTIVE To evaluate the frequency and determinants of fatigue in a group of 91 consecutive patients with ALS, with ...

BACKGROUND Human factors involved with visual attention mechanism and fatigue are critical causes of modern aviation accidents. OBJECTIVE To investigate the connection between attention and flight fatigue, a mathematical model of pilot's visual attention allocation was established based on information processing channels. Multi-task condition and current psychophysical state were taken into a...
