EMG & NCV

Electromyogram (EMG) is a test that is used to record the electrical activity of muscles. When muscles are active, they produce an electrical current. EMGs can be used to detect abnormal electrical activity of muscle that can occur in many diseases and conditions, including inflammation of muscles, pinched nerves, peripheral nerve damage (damage to nerves in the arms and legs), disc herniation, and others.

A nerve conduction velocity test (NCV) is an electrical test that is used to determine the adequacy of the conduction of the nerve impulse as it courses down a nerve. This test is used to detect signs of nerve injury. A nerve conduction velocity test is often done at the same time as an (EMG) in order to exclude or detect muscle conditions.

Symptoms that might prompt a the need for an EMG/NCV include numbness, tingling, and/or burning sensations.
