A negative test means results are normal; a positive test result will reveal some degree of nerve damage (neuropathy).

Certain drugs that act on the nervous system (such as muscle relaxants) can interfere with electromyography results. You may need to stop taking these three to six days before the test. Have had bleeding problems or are taking blood thinning drugs, such as (®) or .

Clench fist and hold for two seconds, release the clench and wait for two seconds. Repeat for three more cycles with increased clench force until the maximum clench is achieved. Try to increase the strength in equal increments such that the fourth clench is the maximum force.
