Electromyography (EMG) is the subject which deals with detection, analysis and utilization of electrical signals emanating from skeletal muscles.⁽¹⁾
The electric signal produced during muscle activation, known as the myoelectric signal, is produced from small electrical currents generated by the exchange of ions across the muscle membranes and detected with the help of electrodes. Electromyography is used to evaluate and record the electrical activity produced by muscles of a human body. The instrument from which we obtain the EMG signal is known as electromyography and the resultant record obtained is known as electromyogram.⁽²⁾
