Don't be sorry for asking a question Al. :razz:
The only "do not" instruction given to me before EMG - was "do not wear any body lotion".
But, I found these instructions today.
How To Prepare
Tell your doctor if you:
Are taking any medicines. Certain medicines that affect the nervous system can change electromyogram (EMG) results. You may need to stop taking these medicines 3 to 6 days before the test.
Have had bleeding problems or take blood thinners, such as warfarin or heparin. If you take blood thinners, your doctor will tell you when to stop taking them before the test.
Have a pacemaker.
Do not smoke for 3 hours before the test.
Do not eat or drink foods that contain caffeine (such as coffee, tea, cola, and chocolate) for 2 to 3 hours before the test.
Wear loose-fitting clothing so your muscles and nerves can be tested. You may be given a hospital gown to wear.
