What Will Happen During the Test?

NCS

During the Nerve Conduction Studies (NCS), the scientist will apply small electrical shocks to your nerves to study how they function. These shocks cause a quick, mild, tingling feeling. The Neurologist in charge of the clinic will determine exactly which nerves are to be studied, depending on the details of your clinical presentation. Several nerves will typically be studied during your visit.

Once the test testing is completed, the Neurologist will evaluate your results and then explain these to you. A comprehensive report will be sent to your referring Doctor, usually within 24 hours (most medical practices accept electronic reports and, if this applies, the report will normally be received on the same day as your tests are performed).

EMG

There are two parts to this test:

  • NCS (please see above)
  • EMG

During the Electromyography (EMG) testing, the Neurologist inserts a small, thin needle into several of your muscles. The Neurologist is able to hear and see how your muscles and nerves are working through analysis of the electrical signals recorded by both the needle and the EMG machine. The Neurologist will then discuss with you their analysis of your symptoms. A comprehensive report will be sent to your referring Doctor, usually within 24 hours (most medical practices accept electronic reports and, if this applies, the report will normally be received on the same day as your tests are performed).

qEMG

When appropriate, we perform computerised Quantitative EMG (qEMG) in conjunction with EMG. This is done offline on a computer, so there is no discomfort involved.

Note: You do not need to do anything to prepare for each of these tests.
