EMG Laboratory

EMG and NCS tests are done in order to evaluate the condition of nerves and muscles. During the test there may be a very mild electrical stimulation applied to your extremities, and a very thin electrode-needle will be inserted into some of the muscles in order to observe their reactions. The test makes use of highly-sophisticated computerized equipment, which allows calculations of the rate at which your nerves conduct electrical impulses, and it assesses whether or not your muscles may have had some interruption in their nerve supply, or whether there is any damage in the muscles. This gives your doctor information about such disorders as injured nerve roots, damaged nerve and muscle disorders, which will allow a better understanding of your problem and provide for the best possible treatment. There is often some discomfort during the procedure, but it is usually mild, and you should feel free to ask for an explanation or a rest in between various parts of the study as it progresses. Generally, the complete examination requires an hour. Please do not use any lotion, ointments, creams, or powder on your skin for 24 hours prior to the test. Clean skin is imperative. However, you may use deodorant. |
