INTRODUCTION Bio-mathematical models are increasingly used for predicting fatigue in airline operations, and have been proposed as a possible component of fatigue risk management systems (FRMS). There is a need to continue to evaluate fatigue models against data collected from crews conducting commercial flight operations. METHODS A comparison was made between several in-flight studies of pil...

This study examines whether the general level and rate of change of fatigue over time is different for those rheumatoid arthritis (RA) patients with and those without a history of affective disorder (AD). Four hundred fifteen RA patients from a national panel had yearly telephone interviews to obtain fatigue and distress reports, and a one-time semistructured assessment of the history of depres...

PURPOSE The purpose of this study was to evaluate the effectiveness of foot reflexology on fatigue, sleep and pain. METHODS A systematic review and meta-analysis were conducted. Electronic database and manual searches were conducted on all published studies reporting the effects of foot reflexology on fatigue, sleep, and pain. Forty four studies were eligible including 15 studies associated w...

Simplified fatigue and fracture mechanics based assessment methods are widely used by the industry to determine the structural integrity significance of postulated cracks, manufacturing flaws, service-induced cracking or suspected degradation of engineering components under normal and abnormal service loads. In many cases, welded joints are the regions most likely to contain original fabricatio...

PURPOSE/OBJECTIVES To examine the relationship between hope and fatigue (intensity, duration, and interference) in newly diagnosed patients with cancer receiving chemotherapy. DESIGN Cross-sectional and correlational. SETTING Oncology outpatient clinics of two medical centers in northern Taiwan. SAMPLE 182 patients diagnosed with various types of solid tumors in the previous six months an...

We present an experimental paradigm to measure changes in characteristics of speech under vocal fatigue. As speech material, we have chosen a vocal load (3 hours) and a cognitive process (aloud continuous reading) that can induce some fatigue of the reader. The fatigue is verified using an analysis of reading errors and of disfluencies. A multivariate analysis based on Wilks' lambda test, on 16...

OBJECTIVE To determine the association between the 5 subscales of the Multidimensional Fatigue Inventory (MFI-20) and physical function in late mid-life. DESIGN Cross-sectional study. SUBJECTS A population-based sample of adults who participated in the Copenhagen Aging and Midlife Biobank population cohort (n = 4,964; age 49-63 years). METHODS Self-reported fatigue was measured using the ...

BACKGROUND The definition of Chronic Fatigue Syndrome (CFS) overlaps with definitions of insomnia, but there is limited knowledge about the role of insomnia in the treatment of chronic fatigue. AIMS To test if improvement of insomnia during treatment of chronic fatigue was associated with improved outcomes on 1) fatigue and 2) cortisol recovery span during a standardized stress exposure. ME...
