Nerve study, or electromyography measures the electrical activity of muscles as they move – contract and relax – and looks at the efficiency of the nerves as they send and receive messages.
When there is a disruption in the signal between the nerves and the muscle, the result is abnormal muscle function which can cause numerous issues, such as pain, numbness, tingling, and weakness.
Patients who suffer from pain, numbness, or other nerve related symptoms often benefit from a nerve study which can tell the physician useful information, such as:
- Do you have a disease that has damaged the muscle or nerves or other tissues, like a herniated disk or ALS
- Is there an underlying cause for weakness or paralysis in the body or limbs of nerve origin
- Has the nervous system been damaged
- What are the chances the injured nerve or muscle will recover
The electrical activity of the muscle and tissues is recorded and studied by your physician. This is a diagnostic test which can determine if the cause of the dysfunction or disease has a neurologic origin.
