Electromyography (EMG) and Nerve Conduction Studies (NCS) are specialized diagnostic tests used to evaluate the health and function of your muscles and the nerves that control them. These tests play a crucial role in identifying problems within the neuromuscular system and help physicians determine the cause of symptoms such as numbness, tingling, pain, muscle weakness, cramping, or abnormal movements.
Electromyography (EMG) measures the electrical activity produced by muscles at rest and during contraction. During this test, a very thin needle electrode is gently inserted into specific muscles to record their electrical signals. EMG helps identify abnormalities in muscle function that may be caused by nerve disorders, muscle diseases, or issues with the connection between nerves and muscles. It is particularly useful in diagnosing conditions such as muscle weakness, muscle spasms, and disorders affecting motor neurons.
Nerve Conduction Studies (NCS) focus on how well and how fast electrical signals travel through your nerves. Small surface electrodes are placed on the skin, and mild electrical impulses are delivered to stimulate the nerves. The speed and strength of these signals provide important information about nerve health. NCS can detect nerve damage, compression, or dysfunction and is commonly used to diagnose conditions such as peripheral neuropathy, carpal tunnel syndrome, radiculopathy, and nerve injuries.
When performed together, EMG and NCS provide a comprehensive evaluation of both muscle and nerve function, allowing for accurate diagnosis and targeted treatment planning. Our board-certified neurologists use advanced technology to ensure precise, reliable results while prioritizing patient comfort and safety. These studies help guide appropriate treatment, monitor disease progression, and support better long-term outcomes for patients with neuromuscular conditions.
