Neurology

NERVE CONDUCTION STUDIES (NCS) - a non-invasive test that measures the velocity/speed of an electrical impulse on the nerve being tested. Most commonly used to help diagnose:

1. Pinched/entrapped nerve. Ex: CTS, tarsal tunnel, cubital tunnel
2. Neuropathy (slowing of the nerves in general)
3. Neuromuscular disorders

ELECTROMYLOGRAM (EMG) - an invasive test where a needle is inserted into certain muscles to evaluate the electrical activity of that muscle. It records the electrical activity with the muscle at rest and when contracting. Most commonly used to help diagnose:

1. Source or cause of a muscle problem
2. Nerve damage from a compressed disc
3. Neuromuscular disorders
4. Inflammation or degeneration of peripheral nerves

ELECTROENCEPHALOGRAM (EEG) - a non-invasive procedure where tiny electrodes are placed on the patients’ head that detect the electrical impulses of the brain. Sometimes different activation procedures are preformed to elicit different wave forms, such as photic stimulation and hyperventilation, depending on the health and age of the patient. EEG’s are most commonly used to help diagnose:

1. Seizure disorders
2. Strokes
3. General health of the brain
