NCVs are performed by attaching two types of electrodes to your skin.
It is possible for your doctor to move the electrode to a different muscle or to a different part of the muscle. While the electrical activity is being recorded, your doctor will ask you to tighten the same muscle slowly and steadily. When the needle electrode is inserted into a muscle, you may experience a quick, sharp pain. The electrical activity of the muscle will be recorded while it is at rest. A needle electrode will be inserted into a muscle during an EMG. The number of nerves and muscles your doctor tests will determine how long it will take. A nerve conduction velocity test can take between 15 minutes and an hour. The duration of an EMG may range from 30 to 60 minutes.
