muscle fatigue assessment has been the basis of numerous studies, specifically, in neuromuscular rehabilitation and the applications of fessystems. various emgbased techniques, in time and frequency domains, have been investigatedover years for the detection and evaluationof this phenomenon. the main objective of this study has beento evaluate the efficiency of applying a number of techniques w...

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...

inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. so the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and beclomethasone against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pi...

conclusions the resistance training of moderate to high intensity was well-tolerated in ms patients and may be an effective intervention for improving muscle strength, functional ability and edss-based disease severity. results two patients of group e left the program. the other eight subjects completed the program with no ms-related exacerbations/complications. there was a significant change i...

objective massage therapy is one of the most widely used complementary and alternative medicine therapies for children. this study was conducted to determine the effect of swedish massage on the muscle tonicity of children with spastic cerebral palsy (cp). materials & methods this study was a single blind clinical trial conducted on forty children with spastic cp, recruited from clinics of the ...

purpose the purpose of the present study was to evaluate effects of regular practice of sun salutation on muscle strength, general body endurance and body composition. methods subjects (49 male and 30 female) performed 24 cycles of sun salutation, 6 days a week for 24 weeks. upper body muscle strength was determined by 1 repetition maximum (1rm) for bench press and shoulder press technique. bac...

up to date, there are four pharmacologically characterized subtypes of muscarinic receptors (m1, m2, m3 and m4). in our study we have investigated muscarinic receptor subtypes in smooth muscle layers of human stomach. isolated preparations of longitudinal and circular muscle layers from human stomach were used. acetylcholine, bethanechol, carbachol, pilocarpine and ahr -602 produced concentrati...

the environmental scanning electron microscopy (esem) is a new development in the field of electron microscopy. in this study esem has been used to study the structure of veal semimembranosus muscle. four treatments, raw (control), conventional heating, domestic and industrial microwave heating, were observed using esem. the temperature used in conventional heating was 163 0c. frequency app...

Background:  Some studies show that frozen shoulder is due to the pathologic changes in the muscles around the shoulder. Measurement of the ultrasonic thickness of a muscle is a method for measuring the muscle changes. There is no study about the reliability of measurement of the muscle’s ultrasonic thickness around the shoulder in patients with frozen shoulder. The present study aims to invest...
