EMG – 2 Limbs is a specialized electrodiagnostic test that evaluates muscle activity in two limbs to assess nerve and muscle function. It is performed to investigate weakness, pain, numbness, tingling, muscle wasting, nerve injuries, radiculopathy, peripheral neuropathy, and other neuromuscular disorders, supporting accurate diagnosis and treatment planning.

Yes. EMG can identify muscle changes associated with nerve injury, nerve-root dysfunction, peripheral nerve disorders, and other neuromuscular conditions. Nerve conduction studies (NCV) may be performed along with EMG when a more comprehensive nerve assessment is required.
Usually, no special preparation is required. Wear comfortable clothing that allows access to the examination area and keep the skin clean. Avoid applying lotion, cream, or oil to the areas being tested.
You may experience mild discomfort when the needle electrodes are inserted, but the procedure is generally well tolerated.
People with unexplained weakness, numbness, tingling, muscle cramps, radiating pain, or suspected neuromuscular disorders affecting the arms or legs may be advised to undergo this test.
EMG 2 Limbs evaluates muscles and nerves in either the arms or legs, while EMG 4 Limbs assesses both arms and both legs for a more comprehensive evaluation.
