when stretcher came to unit and i was put in my bed, nursing personnel of surgical ward said to me hello. i had seen their face from yesterday night when they were transferring patients from emergency ward to this unit.  in that time, i had the role of emergency ward assistant manager. today, i am a weak patient that even is unable for smallest movement. cause of my admission to hospital is mus...

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 avai...

introduction: repetitive strain injuries are one of the most prevalent problems in occupational diseases. repetition, vibration and bad postures of the extremities are physical risk factors related to work that can cause chronic musculoskeletal disorders. repetitive work on a computer with low level contraction requires the posture to be maintained for a long time, which can cause muscle fatigu...

background: surface electromyography (semg) of muscles is a non-invasive tool that can be helpful in the assessment of muscle function and some motor control evaluations. a loss of force, known as muscle fatigue is accompanied by changes in muscle electrical activity. one of the most commonly used surface emg parameters which reflects paraspinal muscle fatigue during different tasks and positio...

background: fatigue can cause a significant effect on the mechanics of complex motor skills and reduce physical and mental efficiency. one of the common ways to reduce fatigue is passive recovering or using massage and cryotherapy after exercise. the present study aimed to compare the effects of massage and cryotherapy on muscles fatigue and isokinetic parameters. methods: this study was conduc...

Background: Muscle fatigue has been known to influence brain activity, but very little is known about how cortical centers respond to muscle fatigue.Objective: This study was conducted to investigate the effects of muscle contraction and fatigue induced by two different percents of maximal voluntary contraction (MVC) on Electroencephalography (EEG) signals.Material and Methods: In t...
