Electromyography (EMG) is the study of a muscle function through the inquiry of the electrical signal the muscles emanate. Although it was invented by Luigi Galvin way back in 1791, it has come into use only in recent times. EMG was largely used during the Second World War on wounded soldiers, and since then, it has got widespread use in almost all the clinical hospitals, academic medical schools and multinational multispecial superspecialized corporate hospitals. Therefore, in this study, we set up a multi-channel real-time power amplifier set for effective medical diagnostics. The amplifier is designed in such a way that it captures the EMG signals with special reference to the physiology of the upper limb and anatomical structure, and flexor aspect of forearm muscles of the subject having an input impedance more than 300 (Mega Ohms). The technical specifications and performance of the instrumentation influence the accuracy of measurement so that meaningful recording of electrical activity can be performed with properly designed equipment.
