EMG - Patient Instructions
You can expect the test to last up to 1 hour. The first part of the study is usually the nerve conduction test. This involves stimulating nerves using a tiny electric current, and recording the responses with surface electrodes on the outside of the skin. The electrical current causes tingling and some muscle twitches, but is not usually painful. The second part of the test is the needle examination. This involves inserting a tiny needle into some muscles in your arm or leg, and recording the electrical activity. Please take all of your medications as usual on the day of the test. Please do not put any kind of lotions on your skin on the morning of the test, as this can interfere with the recordings. You will be able to do normal activities after the test. Please wear gloves one hour before the test so that your hands are warm. Note to all Medicare patients: please note medicare (and secondary insurance) will deny payment for the use of disposable needles during the test. The charge for this is $20.00, and will be expected at the time of service.
