+ | Clinically, EMG is sometimes done with both an excitatory stimulus pulse, which causes the muscles to contract, as well as the EMG sensing. This provides a measure of nerve conduction and propagation time. EMG electrodes were originally coupled to audio amplifiers as the sonified electrical activity is contained in an audible spectrum. It was especially useful to diagnose myotonia, where a frequency modulation would be audible creating sounds similar to a " | ||
