As for clothing, it is not as much what you wear as it is what you don t wear. Since in a great majority of cases the low back and buttocks area may need to be studied or in cases of neck problems, the back of the neck and shoulder areas studied, it is best not to wear clothes which will interfere with access to these areas. However, if you are taking a blood thinner, you should notify the Lab where your EMG is being done, since in that case the needle part of the test may cause bleeding inside the muscle. Also if you are on any medication for Myasthenia Gravis such as Mestinon or other, your medication may interfere with the test, so you should also notify the Lab. If you have any doubts about other medications you are taking, it is best to check with the Lab to be on the safe side.
Different labs have different policies about pain medication.
Some physicians may recommend you take two Aspirins or Tylenols before the test. Others may mail you a prescription drug to take an hour before the test. Sometimes you may be given an injection prior to the test. It is common however, that no sedation is given in any form since in most instances, patients wish to return to work or other regular activity after the test is completed. Another reason for not giving sedation is that you should always have someone accompany you to drive you home after receiving sedation and this is not always easy to arrange.
