Electromyography, or EMG, is a test that measures the electrical activity of muscles. Learn more about this test, nerve conduction, and neuromuscular disorders. Topics A-Z Slideshows Images Quizzes Medications Medical Dictionary The doctor will look at and listen to the electrical signals that travel from the needle to the EMG machine. The doctor then reads these signals. How long will these tests take? The tests usually take 40 to 90 minutes.

Electromyography (EMG) and nerve conduction tests are performed in order to evaluate the condition of nerves and muscles. www.emglaboratory.com EMG (Electromyography) Test Video is a medical educational video explaining the EMG test in details. EMG Laboratory is a state-of-the-a... The EMG Lab is on the 7th floor of University Hospital.

An EMG test is a detailed investigation of the health of your peripheral nervous system (basically, this means all of the nerves outside your brain and spinal cord). There are 2 parts to the test, nerve conduction testing, and an optional needle exam (see below). In the nerve conduction studies (NCS), various nerves, usually in the arm or leg, will be stimulated with a small, harmless electrical pulse. The response from your nerve is recorded by an EMG machine. What medical training do doctors who do EMGs have? Doctors who do EMGs go to 4 years of medical school; and then have 3 or 4 more years training in a residency program. Most work as neurologists or physical medicine and rehabilitation doctors. Medical training helps the doctor decide which tests to perform based on your problems. The person who administers the test will explain the procedure. Often muscle activity is monitored through a speaker during the test, which may make a popping or soft roaring noise. The EMG technician will be looking at an oscilloscope, which looks like a small TV set during the procedure. Testing may take 30 to 60 minutes. After the EMG Procedure If the patient is having this test in a doctor's office, he or she will be sent home following the procedure without any restriction of activities.
