Nerve Conduction Studies

This study measures how fast an electrical impulse can travel through your nerve. Electrodes are placed on the skin over the affected nerve. Multiple small electrical pulses are given to the nerve and the resulting electrical activity is recorded. Depending on the symptoms, several nerves may be tested. These impulses cause electrical sensations that may cause a quick, tingling feeling. This test may take half an hour to 45 minutes, depending on how many nerves and muscles are being tested.
