Background: Muscle fatigue is an important issue in neuromuscular rehabilitation. Better control of this phenomenon would result in better prevention of its consequent physiological damages.Objective: To provide a mathematical representation of muscle fatigue as a function of time.Methods: We conducted this study by combining the EMG-based estimation methods of muscle activation with the availa...

OBJECTIVE Fatigue is an important outcome for patients with rheumatoid arthritis (RA). The purpose of this study was to identify the scales being used to measure RA fatigue, and to systematically examine the evidence for their validation. METHODS Articles measuring fatigue in RA were sought using the terms RA and fatigue, and RA and tiredness, plus scale, questionnaire, inventory, and checkli...

INTRODUCTION Several differences have been reported in the clinical characteristics of chronic obstructive pulmonary disease (COPD) between men and women. Differences have been found in the association between respiratory symptoms and lung function, and in the factors associated with dyspnea. This raises the question of whether there are differences between the sexes in the relationship between...

OBJECTIVES The aim of this study was to determine the effects of pain and fatigue on daily life activities of systemic lupus erythematosus (SLE) patients. METHODS The study sample included 74 SLE patients who presented to outpatient departments of a university hospital and two local hospitals between 30.9.2009 and 15.5.2010. Data was collected using the Fatigue Severity Scale, Katz's Activity...

Effective treatments for multiple sclerosis (MS)-associated central fatigue have not been established. Surface functional electrical stimulation (FES), which can challenge the peripheral neuromuscular system without overloading the central nervous system, is a relatively safe therapeutic strategy. We investigated the effect of 8 weeks of surface FES training on the levels of general, central, a...

BACKGROUND Circadian rhythm sleep disorders are a presentation of sleep disorders in patients with multiple sclerosis (MS). This study aims to compare this problem in MS patients with healthy people and to determine its association with chronic fatigue in MS patients. MATERIALS AND METHODS A case-control study was performed on 120 MS patients and 60 healthy subjects matched for age and sex, i...

 Background & Objective:  Fatigue is defined as a feeling of disability and weakness that leads to a reduction in the capacity of individuals to do their job and daily activities. Sleep disorders are one of the most important causes of fatigue in nurses. The present study aimed to determine the level of occupational fatigue and sleep quality among nurses working in various wards of public hospi...

Post-stroke fatigue is still a relatively unexplored, often neglected condition. The fatigue often manifests as physical and mental lack of energy, and many patients mention fatigue as one of the most difficult sequels to which they have to adjust. Our aim was to assess the fatigue in 35 three-month post-stroke patients and its relation to personal and stroke-related factors, and to compare the...

Muscular fatigue refers to changes in the domain of amplitude and frequency for the muscle contractions. Muscle fatigue is important to the researchers for being familiar with muscle mechanism, rehabilitation, ergonomics, electrical functional stimulation and prosthesis control. Moreover, its significance to clinical research to identify weak muscle and demonstrate the strength training exercis...

Pulmonary hypertension is a potentially fatal disease. Despite pharmacological advances in pulmonary hypertension, fatigue remains common in patients with pulmonary hypertension. A convenience sample of 120 participants at an international patient conference completed the Multidimensional Fatigue Inventory (MFI)-20 scale. Data on New York Heart Association Functional Class, body mass index, oxy...
