Rectification of EMG signals is a common processing step used when performing electroencephalographic-electromyographic (EEG-EMG) coherence and EMG-EMG coherence. It is well known, however, that EMG rectification alters the power spectrum of the recorded EMG signal (interference EMG). The purpose of this study was to determine whether rectification of the EMG signal influences the capability of...

The purpose of this study was to assess the effects transverse friction massage (TFM) on electromechanical delay components and complexity surface activity in rectus femoris (RF) vastus medialis (VM) muscles identify possible mechanisms behind TFM-induced alterations dynamics RF VM activity. Seven female five male healthy subjects participated study. generated maximal voluntary isometric contra...

Objective: Habitual walking is important for health and can be measured with accelerometry, but accelerometry does not measure physiological effort relative to capacity. We compared accelerometer-measured absolute intensity electromyography (EMG)-measured muscle activity between people low versus excellent aerobic fitness levels during their habitual walking. Methods: Forty volunteers (19 women...

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...
