Electromyography was developed to investigate the electrical responses of nerves and muscles and assess the loss of nerve distribution in muscles. In addition, electromyography can also measure the speed of motor conduction, sensation and peripheral electrical diagnosis.

Electromyography with needle electrodes is a widely used method in diagnosing neurological and muscular diseases. This is the basis for doctors to give the most appropriate treatment options for patients.

Electrodiagnostics is often called electromyography, electromyography, neuromuscular electrophysiology. This is a method of recording the electrical activity of nerve cells and muscle cells, detecting abnormalities in electrical activity to help diagnose peripheral neuropathy, muscle disease and neuromuscular junction (neuromuscular synapse).
