Electromyography (EMG) Testing in Brisbane
Electromyography (EMG) is a specialised diagnostic test used to assess muscle function and nerve communication. It helps detect nerve or muscle disorders by recording the electrical activity in muscles.
At Brisbane Clinical Neuroscience Centre (BCNC), we offer comprehensive EMG testing, including:
- Needle Electromyography (EMG) – Evaluates muscle and nerve function.
Single Fibre EMG – A specialised test for neuromuscular junction disorders.
These tests are performed by experienced neurologists in a controlled, clinical environment to ensure accuracy and patient comfort.

What is an EMG Test?
An EMG (Electromyography) test measures the electrical activity of muscles to evaluate their function in response to nerve signals. It is commonly used to diagnose conditions affecting nerves and muscles, such as:
- Muscular dystrophy
- Myasthenia gravis
- Amyotrophic lateral sclerosis (ALS)
- Nerve damage from injuries or medical conditions
EMG testing is typically recommended when patients experience:
- Tingling or burning sensations
- Muscle weakness or fatigue
- Persistent muscle pain or cramping
- Numbness in the limbs
These symptoms may indicate an underlying neuromuscular disorder, and EMG can assist in diagnosis and treatment planning.
Types of EMG Testing
Needle Electromyography (EMG)
Needle EMG involves inserting a fine needle electrode into the muscle to measure electrical activity at rest and during movement. This test helps assess muscle and nerve health and can identify nerve injuries or muscle disorders.
Commonly used to assess:
- Nerve compression disorders (e.g., carpal tunnel syndrome).
- Muscle diseases such as muscular dystrophy.
- Motor neuron diseases like ALS.
While mild discomfort may be experienced during the test, it is a well-tolerated and essential diagnostic tool. Your neurologist will guide you through the procedure.
Single Fibre Electromyography (EMG)
Single fibre EMG is a highly specialised test that examines individual muscle fibres to assess neuromuscular junction function. It is particularly useful for diagnosing conditions like myasthenia gravis, which affects how nerves communicate with muscles.
How it works:
- A fine needle electrode records the time intervals between muscle fibre activations.
- Helps detect subtle changes in nerve-to-muscle communication.
This test is often performed when a standard EMG does not provide sufficient diagnostic information.
