What is a NCV & EMG BRACHIAL PLEXUS?

NCV (Nerve Conduction Velocity) and EMG (Electromyography) are complementary diagnostic tests used to evaluate the health of nerves and muscles. When performed for the brachial plexus—the network of nerves that extends from the neck to the shoulders, arms, and hands—these tests help neurologists identify nerve damage, compression, or disorders affecting nerve and muscle function, supporting accurate diagnosis and treatment planning.

FAQs

What is NCV & EMG Brachial Plexus?

NCV & EMG Brachial Plexus is a combined electrodiagnostic test that evaluates the function of the nerves and muscles associated with the brachial plexus, the network of nerves connecting the neck to the shoulder, arm, and hand.

Why is NCV & EMG Brachial Plexus performed?

It is used to diagnose brachial plexus injuries, nerve compression, nerve root disorders, and other conditions causing pain, numbness, tingling, or weakness in the upper limb.

What symptoms may require this test?

The test may be recommended for persistent shoulder pain, arm weakness, numbness, tingling, loss of sensation, or suspected nerve injury following trauma or surgery.

Is the NCV & EMG Brachial Plexus test painful?

NCV may cause mild discomfort from electrical stimulation, while EMG may cause brief discomfort due to the insertion of a fine needle electrode into selected muscles.

What is the difference between NCV and EMG?

NCV measures the speed and strength of electrical signals traveling through nerves, while EMG evaluates the electrical activity of muscles.

Who may need NCV & EMG Brachial Plexus testing?

Individuals with symptoms of brachial plexus injury, upper-limb weakness, sensory changes, nerve compression, or unexplained arm and shoulder pain may be advised to undergo this test.
