A number of studies have examined the validity of using spectral parameters, such as median frequency (Fmed) and Dimitrov spectral index of muscle fatigue (FInsm5) from the surface EMG signal during dynamic exercise, to assess muscle fatigue. Despite these studies, the ability to accurately predict endurance capacity using these spectral parameters during repetitive dynamic contractions is limited...
A study was conducted to investigate the effect of light assembly task on upper limb muscles (biceps brachii and upper trapezius) and brain activities. The task was conducted in two levels of time pressure (No time-stress and time-stress levels). Each task was done for one hour experiment. Surface electromyography (SEMG) measured upper limb muscle activities from six subjects. The results indicated...
The surface electromyographic (SEMG) signal, which is produced by neural and muscular systems, is a complicated bioelectric signal recorded from skin surface using electrodes. It is very helpful for doctors to analyse the illness of patients. In the paper, four channel SEMG signals from four muscles (palmaris longus, brachioradialis, flexor carpi ulnaris, biceps brachii) are analyzed with wavelet...
