INVOLVES TWO PARTS:
1. Electrical pulses: During the test, several nerves will be stimulated by an electric stimulator and then recorded. If a nerve is damaged, these electrical impulses may be slow.
2. Tiny Needles: A small acupuncture like needle may be inserted into several muscles, to listen for electrical activity. No electricity is used with the needles. Damaged muscles sound different than healthy muscles sound. The physician will determine if needle testing is required.
