What Is an EMG Test?
At Ruby Hospital, we offer Electromyography (EMG)—a specialized diagnostic test used to assess the health of your muscles and nerves. This test helps identify the root cause of symptoms like muscle weakness, numbness, pain, or tingling in the arms, legs, or other areas.
An EMG test is performed by a neurologist or trained specialist and involves measuring the electrical activity in your muscles and nerves. It typically includes two parts:
-
Needle EMG – evaluates the electrical signals in your muscles.
-
Nerve Conduction Study (NCS) – checks how fast and efficiently electrical signals travel through your nerves.
These two tests are often done together to provide a complete picture of how well your nerves and muscles are working. The procedure is safe, done on an outpatient basis, and usually takes less than an hour.
What’s the Difference Between EMG and Nerve Conduction Studies (NCV)?
While EMG and NCV are often performed together, they serve different purposes:
-
EMG focuses on muscle activity, using fine needles inserted into the muscle to monitor electrical signals at rest and during contraction.
-
NCV (Nerve Conduction Velocity) tests the speed and strength of nerve signals, using small electrical impulses placed on the skin.
Together, they help determine if symptoms like weakness or pain are caused by nerve damage, muscle disease, or both.
What Does an EMG Test Detect?
An EMG test is crucial in diagnosing several conditions, including:
-
Muscle weakness – helps determine whether it’s due to nerve damage or muscle disorders.
-
Abnormal muscle activity – detects spasms, involuntary twitches, or other irregularities.
-
Pinched or compressed nerves – commonly used to diagnose carpal tunnel syndrome or sciatica.
-
Neuromuscular disorders – such as muscular dystrophy, ALS, or peripheral neuropathy.
By identifying the exact problem, our specialists at Ruby Hospital can develop personalized treatment plans to help you recover faster and better.
How Long Does an EMG Test Take?
The duration depends on how many areas are being tested. Most EMG and NCV tests take 30 minutes to 1 hour. In more complex cases, additional sessions may be needed.
Is an EMG Test Painful?
Most patients describe the EMG test as mildly uncomfortable but not painful. The sensation is similar to a quick pinch or muscle twitch. You might experience slight soreness afterward, but this typically fades within a few hours.
Understanding Your EMG Results
-
Normal EMG results indicate healthy nerve and muscle function.
-
Abnormal results may point to conditions such as nerve damage, myopathy, or neuromuscular diseases.
