Electromyography (EMG) in Montreal: Diagnosing nerve and muscle disorders
Our clinic in Montreal provides electromyography (EMG) tests to diagnose and evaluate nerve and muscle disorders. This specialized exam helps pinpoint the causes of pain, numbness, or muscle weakness. Using advanced technology, our team of specialists analyzes the electrical activity of muscles and nerves to provide a clear diagnosis and support neuromuscular care.

Electromyography (EMG) is a medical test that measures the electrical activity generated by muscles in response to nerve stimulation. By using surface electrodes or fine needles, this exam detects abnormalities in nerve transmission or muscle contraction, offering detailed insights into the health of muscles and peripheral nerves.
An EMG is recommended in cases such as:
-
Diagnosing pain and numbness in the limbs
-
Identifying conditions like carpal tunnel syndrome, neuropathies, and radiculopathies
-
Evaluating muscle weakness and cramps
-
Diagnosing neuromuscular diseases such as amyotrophic lateral sclerosis (ALS) or myopathies
-
The EMG test has two main steps:
-
Nerve conduction study: Small electrical impulses are applied to nerves to assess their conduction. This step evaluates the speed and strength of nerve transmission.
-
Muscle activity study: Using fine needles inserted into muscles, this phase measures the electrical activity of muscles at rest and in contraction, providing detailed insights into muscle function.
Most patients tolerate the EMG well, though some may experience mild discomfort during the test.

Once the test is completed, our specialists analyze the results and provide a detailed report. Based on the findings, we create a personalized treatment plan, in coordination with your physician, to help you better understand and manage your condition.
