Do you suffer from pain with no known cause? Hillside Rehabilitation Hospital may be able to help.
Hillside Rehabilitation Hospital offers Nerve conduction studies/Electromyography (NCS/EMG). NCS/EMG is a diagnostic test for individuals suffering from muscle pain, cramping, tingling, numbness or weakness with no known cause. The test can help determine if the pain is a muscular problem or a nerve problem.
Results from an NCS/EMG can reveal nerve or muscle disfunction or other problems with nerve-to-muscle signal transmission, including:
- Nerve disorders, such as carpal tunnel syndrome or peripheral neuropathies.
- Disorders that affect the nerve root, such as a herniated disk in the spine.
- Muscle disorders, such as muscular dystrophy or polymyositis.
- Diseases affecting the connection between the nerve and the muscle, such as myasthenia gravis.
- Disorders that affect the motor neurons in the brain or spinal cord, such as amyotrophic lateral sclerosis or polio.
How does a patient prepare for an NCS/EMG?
The morning of the test it is recommended that patients shower to remove oils from their skin and not moisturize or put lotion on after the shower. It’s also important to avoid caffeine, sugary beverages and smoking the day of the test. The patient should also ask their primary care doctor if they need to stop taking any prescriptions or over-the-counter medications before the test.
What to Expect
The patient will be asked to change into a hospital gown and lie down on an examination table. Electrodes will be placed on the patient’s skin where they are experiencing symptoms. A stimulator will provide a stimulus to the nerve. Also, a pin electrode is inserted into different muscles based on the patient’s symptoms.
During the NCS/EMG, the physician will assess whether there is any unprompted electrical activity when the muscle is at rest, activity that isn’t present in healthy muscle tissue – and the degree of activity when the muscle is slightly contracted. The patient will be given direction on resting and contracting muscles based on the area being examined.
After the NCS/EMG, the patient’s primary care doctor will receive a detailed report that they will discuss with the patient in a follow up appointment.
