EMG Test Information
What is EMG testing?
- Electromyography (EMG) is a form of electrodiagnostic testing that is used to study nerve and muscle function. EMG testing provides your doctor with specific information about the extent of nerve and/or muscle injury and can also determine the exact location of injury and give indication wether the damage is reversible.
What should you expect?
There are two parts to EMG testing:
- Nerve conduction. The nerve conduction study entails stimulating the nerves at different points with small electric shocks, artificially activating them so their function can be measured.
- Needle exam. This involves inserting very fine needles into several muscles. The needle picks up both the normal and abnormal electrical signals given off by a muscle.
What should you know before the exam?
- Side effects may include some muscle soreness, which rarely lasts more than an hour or two after the exam.
- Patients on anticoagulation or blood thinners and those with pacemakers or implanted defibrillators should notify the physician performing the test, but generally this is not a contraindication.
- Patients on medication should take their usual medication on the day of the test.
- Please come with clean, dry skin and no lotion for accurate testing.
Why has this test been ordered?
- If you have numbness, decreased sensation, tingling, radiating pain, or burning, your doctor may refer you for an EMG.
- Symptoms such as muscle spasms, weakness, and difficulty buttoning clothes, handling object, or walking may also indicate the need for an EMG.
- Conditions that EMG testing helps diagnose include carpal tunnel syndrome, a pinched nerve, radiculothapy, sciatica, neuropathies, muscle diseases, muscular dystrophy, Lou Gehrig's disease, and myasthenia gravis.
*Average pricing for this test ranges between $3,000 and $5,000.
Note: For patients with commercial insurance, we require $250 down at the time of the procedure. This test is not considered an office visit.
