Neurological symptoms can come from many different causes, and physical exams alone don’t always provide enough answers. EMG and EEG tests give neurologists objective data about how nerves, muscles, and brain activity are functioning.
These tests are often ordered to evaluate:
Persistent numbness or tingling
Muscle weakness or cramping
Suspected nerve damage or neuropathy
Seizures or unexplained episodes
Tremors or involuntary movements
Headaches with neurological features
If you’ve been referred for nerve testing near me, these studies help guide accurate diagnosis and treatment.
An electromyography (EMG) test evaluates how well your muscles and nerves work together. It’s commonly used when symptoms suggest nerve compression, nerve damage, or muscle disorders.
During an EMG test, a specialist may perform two parts:
Nerve conduction study
Small electrodes are placed on the skin to measure how quickly electrical signals travel through your nerves.
Muscle activity testing
A very thin needle electrode is inserted into specific muscles to measure electrical activity at rest and during movement.
While the idea of needles can sound intimidating, most patients tolerate EMG testing well. Any discomfort is typically brief and manageable.

An electroencephalogram (EEG) measures electrical activity in the brain. This test is often ordered when patients experience seizures, fainting spells, confusion, or unexplained changes in awareness.
During an EEG test:
Small electrodes are placed on the scalp using a conductive paste
You’ll sit or lie comfortably while brain activity is recorded
The test is painless and does not involve needles
You may be asked to breathe deeply or look at flashing lights
EEG tests help neurologists detect abnormal brain wave patterns that may indicate seizure disorders or other neurological conditions.
Preparation is usually simple. Patients are typically advised to:
Avoid lotions or oils on the skin before the test
Wear comfortable, loose-fitting clothing
Continue medications unless instructed otherwise
Bring a list of current symptoms and medications
Your neurologist will review the results with you and explain what they mean for your care.
Having EMG or EEG testing done locally makes follow-up care easier and ensures continuity between testing and treatment. Local neurologists can quickly interpret results and adjust care plans without unnecessary delays.
If you’re experiencing ongoing neurological symptoms and have been advised to undergo testing, scheduling an evaluation is an important step toward answers and relief.
