In the evaluation of the human motor system, typical output measures of TMS stimulation to the primary motor cortex (M1) are changes in the electromyographs (EMG) of target muscles including, if the stimulation is properly applied, the generation of EMG activity spikes known as magnetic evoked potentials (MEPs).
Not to speak about the big difference between vibrating platforms used in an academic and experimental environment, and vibrating platforms sold or used with imprudence in the common fitness centres (which for example are not provided with electromyograph for detecting the correct frequency of the individual work).
Consisting of a receiver, electrodes, and a data acquisition system, an electromyograph records electrical changes that occur in a muscle during or just prior to contraction.
Back in his bricks-and-mortar lab, Hart uses an electromyograph to track neural pathways involved in frogs' hopping.
Electromyograph (EMG) biofeedback heightens proprioceptive awareness of the mechanisms of muscle flexure and develops voluntary control over dysfunctional, semivoluntary, or involuntary muscle activity.
Electromyograph studies following a loading dose of 5g in 20 minutes showed an 80% reduction in twitch height.
All subjects were connected to an electromyograph to monitor the electrical activity of muscle tissue in their head and neck areas.
For example, an electromyograph may be used to check and control muscle tension to treat tension headaches and back pain.
Erdelyi, Sihvonen, Helm, and Hanninen (1988) measured the EMG of the upper trapezius during typing and found that electromyograph (EMG) activity level decreased as the keyboard height was lowered.

EMG - electromyograph - a continuous record of the intrinsic electrical activity associated with muscle contraction and kinesthesia (swish of skirt and blink of eye).
However, she did not perform any surface electromyograph (EMG) studies on the workings of the muscles and, therefore, was unable to discuss the causes of the myofascial pain.
