Neurophysiology Testing

EMG (electromyography) and nerve conduction studies (NCS) are tests that assess nerve and muscle function. NCS measures how fast and strongly electrical signals travel through your nerves. EMG examines the electrical activity of muscles. Together, these tests help diagnose conditions like carpal tunnel syndrome, neuropathy, radiculopathy (pinched nerves), and neuromuscular diseases.

Most people tolerate testing well. Nerve conduction studies involve mild electrical stimulation that feels like a brief tapping or tingling sensation. EMG involves thin needle electrodes inserted into muscles, which may cause brief discomfort similar to a small pinprick. The discomfort is temporary and most patients are surprised at how manageable the tests are.

Avoid applying lotions, oils, or creams to your arms and legs on the day of testing. Wear loose, comfortable clothing that allows easy access to your arms and legs. Continue taking your regular medications unless your doctor advises otherwise. The test typically takes 30-60 minutes depending on the areas being tested.

Neurophysiology testing helps diagnose carpal tunnel syndrome, ulnar neuropathy, peripheral neuropathy, radiculopathy (pinched nerves in the neck or back), motor neuron disease, myasthenia gravis, muscular dystrophies, inflammatory myopathies, Guillain-Barré syndrome, and various other nerve and muscle conditions.

Single-fibre EMG is a highly specialised test that examines the connection between nerves and individual muscle fibres. It's the most sensitive test for diagnosing neuromuscular junction disorders like myasthenia gravis. This advanced test is performed by our specialist neurophysiologist and is particularly useful when standard testing is inconclusive.

Our neurophysiologist typically discusses initial findings with you immediately after the test. A detailed written report is then prepared and sent to your referring doctor within a few days. If the results require urgent attention, we will contact your doctor directly. Follow-up appointments can be arranged to discuss results and treatment options in detail.
