This term refers to a type of test performed in neurology, most commonly a Nerve Conduction Study (NCS) and an Electromyogram (EMG). Sometimes both tests are performed.
Other types of neurophysiology tests include Electroencephalogram (EEG), Evoked Potentials (EPs) and Vestibular Function Tests (VFTs), but these are not performed at MNG.
Any doctor can order neurophysiology tests, but most commonly these tests are ordered by a Neurologist.
Neurophysiology testing is complicated, and requires specialised training to perform. A/Professor Day is a neurologist who has undertaken detailed training in Australia and USA in neurophysiology, and is widely regarded as one of Australia’s expert neurophysiologists.
Nerve Conduction Studies (NCS) examine the integrity of the peripheral nerves. All peripheral nerves consist of a motor component – which makes the muscles work – and a sensory component – which provide sensation to parts of the limb.
NCS is generally not painful, but some people find it a little uncomfortable.
No special preparation is required before an NCS. You should try to keep your arms and legs warm in the half hour or so before your test, as being cold can affect the results.
An Electromyogram (EMG) examines the function of an individual muscle. As all muscles in the body are supplied by a nerve, studying a muscle can tell us about both the state of the muscle and the state of the nerve that supplies it. An EMG is rarely performed without first doing an NCS.
An EMG can be uncomfortable, but A/Professor Day is an expert and thus able to keep any pain to a minimum. You may experience bruising and mild muscle pain for a few days after the test.
Please inform A/Prof Day if you are taking warfarin or any anticoagulant drugs.
