Electromyography (EMG) and nerve conduction studies (NCS) are two important neurological tests used in the diagnosis of muscle and nerve disorders. While EMG measures the electrical activity of muscles, NCS evaluates the speed and efficiency with which nerves transmit electrical impulses. Together, these tests help diagnose various neuromuscular conditions such as muscle–nerve diseases (including ALS), focal neuropathies (such as carpal tunnel syndrome), peripheral neuropathy related to diabetes and kidney failure, nerve root damage caused by lumbar and cervical disc herniation, myopathies, poliomyelitis, and myasthenia gravis.
EMG is usually performed by a neurologist and is a mildly invasive procedure involving the insertion of fine needles into the muscles. NCS, on the other hand, involves delivering mild electrical stimuli to the nerves through surface electrodes. Both procedures generally cause only mild discomfort and have minimal side effects. Our hospital ensures more accurate diagnoses by using high-technology EMG devices and performing EMG tests exclusively by neurology specialists.
