Background: Nearly 8.5 million of employees in Iran are carpet-weavers and musculoskeletal disorders especially in their shoulder region are prevalent. As regards muscle fatigue is a risk factor for musculoskeletal disorders its reduction may improve health promotion among the weavers and also lead to improved quality and quantity of this national product. Muscle fatigue manifestations in elect...

Abstract Background and aims: Poor sleep and fatigue are common problems among the pre-hospital emergency staff. Pre-hospital personnel shift work can have negative effects on job performance, sleep quality, physical health, mental health, drug consumption, and job stress. One of the complementary and nonpharmacologic interventions to reduce sleep disturbances and fatigue is progressive muscul...

Background and Objectives: Fatigue is a common complaint among patients who undergo hemodialysis. Fatigue influences their somatic, mental, sentimental and cognitive states. This study aimed to determine the effect of progressive muscle relaxation technique on fatigue among patients treated with hemodialysis. Materials and Methods: In this clinical trial, 90 patients undergoing hemodialysis wer...

Objective: Dynamic stability in shoulder is an important element in life and any disorder in muscular function which helps maintain this stability leads to shoulder pathology. One of these disturbing factors is fatigue. According to the research team information until now there has not been a study investigated systematically the effect of fatigue on shoulder girdle biomechanics. So the purpose...

  Background and aims : Long term working in a static and awkward posture is known as an important risk factorof work related musculoskeletal disorders in hand carpet weavers. Inappropriate workstation and awkward posture can increase the electrical activity and fatigue in muscles. The aim of this study was the measurement of muscle load and fatigue by surface electromyography and Borg CR-10 sc...

  Background and aims   Recordings of electrical activity in the muscle and surface electromyography (EMG) have been widely used in the field of applied physiology. In parallel to  recording of the EMG, the detectable low-frequency vibration signal generated by the skeletal  muscle has been known and well documented. As the nature of the signal has been progressively   revealed, the term of mec...

  Introduction: Today, computers are widely used in many homes and workplaces. The relationship between computer use and musculoskeletal disorders in the neck and upper extremities has been well documented. Muscle fatigue in the shoulder and arm regions is one of the most frequently reported problems in computer users. Supporting the upper extremities has been suggested as a way to re...
