EMG & NCV Testing
What Are EMG & NCV Tests?
Electromyography (EMG) and Nerve Conduction Velocity (NCV) tests measure how your muscles and nerves are functioning — not just how they look on imaging.
An EMG records the electrical signals your muscles produce during contraction and at rest. An NCV measures how fast those signals travel along your nerves. Together, they can identify where a problem is, how severe it is, and what tissue is involved.
These tests are most useful when symptoms like numbness, weakness, tingling, or cramping don’t have a clear cause — or when imaging alone hasn’t given your providers a complete picture.
EMG & NCV tests are two of the most precise tools available for diagnosing nerve and muscle conditions.
At Recover Pro, results are reviewed in context with your full clinical picture — not in isolation.
A clear diagnosis when symptoms don't add up
EMG & NCV testing identifies exactly where nerve or muscle dysfunction occurs — giving your providers a precise starting point rather than a best guess.
A treatment plan built around the actual problem
With detailed data on nerve conduction and muscle function, your care team can target the real source of your symptoms rather than treating around it.
Faster progress with less trial and error
When your providers know what’s happening at the nerve and muscle level from the start, your plan skips the guesswork — and you spend less time on treatments that aren’t the right fit.
EMG & NCV Testing for Nerve and Muscle Symptoms
EMG & NCV testing is a good fit for anyone dealing with nerve or muscle symptoms that haven’t been fully explained — or where a diagnosis exists, but treatment hasn’t been working as expected. These tests are most valuable when your care team needs precise data to confirm what’s happening and decide the right next step.
Pinpoint the Source
Identify exactly where nerve or muscle dysfunction is occurring — down to the specific nerve segment or muscle group.
Guide the Right Treatment
Give your providers the data they need to build a plan around the actual problem, not a working hypothesis.
Track Progress Over Time
Establish a functional baseline so future testing can show whether treatment is working and where to adjust.
Diagnostics as the Starting Point of Your Recovery
EMG & NCV testing works best when results feed directly into treatment. Combined with the right rehabilitation, pain management, or recovery services, your findings become the foundation for a plan built around what’s actually driving your symptoms.
EMG & NCV Testing Frequently Asked Questions
When pain, numbness, or weakness doesn’t have a clear explanation, EMG & NCV testing gives your care team the data to act on. Both tests are performed in-office and are generally well-tolerated — NCV testing is typically painless, and EMG involves a small needle that may cause brief, minor discomfort.
These tests are not recommended for patients with implanted electrical devices such as pacemakers, or those with bleeding disorders that make needle insertion risky. If you’re on blood thinners or have any implanted devices, let your provider know before scheduling.
Does the test hurt?
EMG testing involves a small needle, which can cause brief, minor discomfort during insertion. NCV testing is typically painless — most patients notice mild tingling or a brief warming sensation from the electrical impulse. Most patients tolerate both tests without significant issues.
How do I prepare?
Skip lotions, oils, or creams on the day of your test — they can interfere with electrode contact. Wear comfortable clothing that gives easy access to the areas being tested. Let your provider know about any blood thinners or medications you’re currently taking.
What conditions can EMG & NCV testing diagnose?
These tests are commonly used to diagnose peripheral neuropathy, radiculopathy (nerve root compression in the spine), carpal tunnel syndrome, myasthenia gravis, muscular dystrophies, and motor neuron diseases like ALS. They’re also useful for evaluating post-surgical nerve recovery and unresolved pain or weakness after injury.
How long does the test take?
Most sessions run between 30 and 60 minutes, depending on how many nerves or muscle groups are being evaluated. Your provider will let you know what to expect before you arrive.
When will I get my results?
Results are reviewed by your provider shortly after testing and discussed with you in context — not just handed over as raw data. The goal is to walk away with a clear understanding of what the findings mean for your next steps.
Do I need a referral?
No referral is needed to schedule at Recover Pro. If testing is clinically appropriate, your provider can order it as part of your evaluation.
