Neurophysiology / Neurodiagnostic Tests

Neurologic diagnostic investigations such as Nerve Conduction Studies (NCS), Electromyography (EMG) and Electroencephalography (EEG) can all provide vital information in the diagnosis and management of your condition.

Performed by either Dr Costello or our neuroscientist – using specialised computers and software – they are designed to assess the integrity and function of your brain, nerves and muscles.

You may be referred solely for one of these electrophysiologic tests; however your GP may also request a consultation that can be done at the same time, or completed on a separate occasion.

More information on each of these tests is as follows:

EEG (Electroencephalogram)

EEG’s are used to record the electrical activity in your brain by gently applying electrodes to your scalp. Following the EEG a Neurologist will interpret the activity to assist in determining if you have seizures, epilepsy or non epileptic events.

Nerve Conduction Studies

Nerve conduction studies are used to record the size and speed of nerve responses within your peripheral (mostly within your arms and legs) nerves. Analysis of these responses, provides an accurate assessment of the integrity and function of your nerves assisting in your diagnosis.

EMG (Electromyography)

An electromyogram (otherwise known as an EMG) is used to record electrical signals from muscles both at rest and on activation. These signals change when damage to either the muscle or its nerve supply, is or has been present in the past.

EMG’s are often used to provide additional information about your nerves and muscles on top of nerve conduction studies (NCS). In some instance EMG’s are used to conclude a NCS, and provide an accurate diagnosis. EMG’s are not performed as a standalone study.

When and how do I get my results?

Results are not provided at time of the test. All investigations/tests need to be analysed, interpreted, and reported by Dr Costello. Once compiled, your report will be sent to the doctor who referred you and to your general practitioner (if different) as well as to any medical and allied health practitioners who have been involved in your care and treatment.

How much does it cost?

As with all of the services we provide, medicare rebates are available. Our staff will gladly discuss fees and billing procedures with you when you make an appointment.
