To perform nerve conduction studies, our physician will tape small surface electrodes onto the skin and apply a brief electric stimulus to one portion of the nerve. Nerve stimulation will cause a tingling sensation. The physician can then evaluate the electrical response of the nerve or muscle to which the nerve is attached, and determine if the nerve impulse is conducted normally. Nerve damage and its severity are determined when nerve conduction is either slow or not at all present.
The time required for an EMG/NCS study is approximately one hour. There are no restrictions to activities or meals before or after the test, and there are no permanent after effects.
