EMG Two Limbs

Electromyography (EMG) measures responses of the muscle in response to electrical signal. The test is used to diagnose neuromuscular disorders by recording electrical activity of muscle during rest & contraction. An EMG test may be ordered if you have pain, tingling, numbness, or unexplained weakness in the arms or legs. EMG results are able to confirm nerve or muscle disorders or disorders with muscle to nerve transmission.
