EMG and Nerve Conduction Studies
EMG and nerve conduction studies are diagnostic tests used to evaluate how well the nerves and muscles are functioning. These tests can help identify the cause of symptoms such as numbness, tingling, weakness, muscle cramps, or pain.
At Hackensack Neurology, EMG and nerve conduction testing is used to help diagnose a wide range of neuromuscular and peripheral nerve conditions.
What Are EMG and Nerve Conduction Studies?
Nerve conduction studies measure how quickly and effectively electrical signals travel through the nerves. Electromyography, or EMG, evaluates the electrical activity of muscles. Together, these tests can provide important information about whether symptoms are coming from nerves, muscles, or both.
Why EMG and Nerve Conduction Studies May Be Recommended
- Numbness or tingling in the arms or legs
- Muscle weakness
- Suspected neuropathy
- Carpal tunnel syndrome
- Radiculopathy or pinched nerve
- Neuromuscular disorders
- Muscle cramps or unexplained muscle symptoms
What to Expect During the Test
During nerve conduction studies, small electrical impulses are used to assess how well the nerves transmit signals. During the EMG portion, a very fine needle electrode is placed into selected muscles to record their electrical activity. The test may cause temporary discomfort, but it is generally well tolerated.
What the Results Can Show
- Peripheral neuropathy
- Nerve compression such as carpal tunnel syndrome
- Pinched nerves or radiculopathy
- Muscle disorders or neuromuscular disease
- Patterns that help guide diagnosis and treatment
Why This Test Matters
When symptoms affect sensation, strength, or muscle function, EMG and nerve conduction studies can help pinpoint the source of the problem. This information can be essential for making an accurate diagnosis and developing the right treatment plan.
