Which of the following factor determines the amplitude of EMG signal?
Which of the following factor determines the amplitude of EMG signal? Correct Answer Position of electrode
The amplitude of the EMG signals depends upon various factors, e.g. the type and placement of electrodes used and the degree of muscular exertions. The needle electrode in contact with a single muscle fibre will pick up spike type voltages whereas a surface electrode picks up many overlapping spikes and therefore produces an average voltage effect.
