Electromyography (EMG) is an advanced diagnostic test used to assess the electrical activity of muscles and the health of the nerves that control them. At Aayu Hospital, under the expert care of Dr. Vinusha Alamaddi, EMG testing is conducted to pinpoint the cause of muscle weakness, numbness, pain, or abnormal muscle movement.
EMG plays a vital role in diagnosing a wide range of neuromuscular conditions. It is commonly used to evaluate disorders such as radiculopathy (pinched nerves in the spine), peripheral neuropathy, myopathy, motor neuron diseases (like ALS), carpal tunnel syndrome, sciatica, and muscle dystrophies. It is especially helpful when symptoms include unexplained muscle weakness, twitching, or cramping.
During an EMG test, a fine, sterile needle electrode is gently inserted into the muscle to record electrical signals both at rest and during muscle contraction.
