BACKGROUND Fatigue is a common symptom for which patients consult their doctors in primary care. With usual medical management the majority of patients report that their symptoms persist and become chronic. There is little evidence for the effectiveness of any fatigue management in primary care. AIM To compare the effectiveness of cognitive behaviour therapy (CBT) with counselling for patient...
Introduction: This study aimed to investigate the effect of carpet weaving at a proposed workstation on Upper Trapezius (UTr) fatigue during a task cycle. Fatigue in the shoulder is one of the most important precursors for upper limb musculoskeletal disorders. One of the most prevalent musculoskeletal disorders between carpet weavers is disorder of the shoulder region. Methods: This cross-se...
Fatigue. Fundamentals and development into design. 7 Recent fatigue test and measurement technology.
Background:Fatigue and sleep disorders are experienced by most patients with Multiple Sclerosis (MS). Since these problems can interfere with a patient's daily functioning, this research examined the effects of Progressive Muscle Relaxation Technique (PMRT) on fatigue and sleep quality in patients with MS. Methods:This quasi-experimental study adopted a pretest-posttest single group design. ...
The crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form of bending and torsion during its service life. Its failure will cause serious damage to the engine so it’s important at the time of design to verify fatigue strength. More challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher efficiency and lo...
BACKGROUND There are over 25 million people worldwide living with or beyond cancer and this number is increasing. Cancer survivors face a range of problems following primary treatment. One of the most frequently reported and distressing symptoms experienced by cancer survivors is fatigue. There is growing support for survivors who are experiencing problems after cancer treatment to engage in su...
This paper presents the effects of different amounts of reclaimed asphalt on fatigue life of asphalt mixtures. Central composite method was used to design of experiments based on response surface method (RSM). Binder type (Pen 60/70 and Pen 85/100), reclaimed asphalt pavement (RAP) content (25, 50 and 75%) and loading strain (150, 250 and 350 micro strain) were selected as independent variables...
This paper addresses a central question in subjective test design: ”What is the appropriate duration for QoE lab experiments that involve human participants?” Since user tests are time-consuming and costly, this is an important question as it exposes the fundamental challenge of maximizing test duration while avoiding problems arising from undue strain on test participants. We provide an extens...
