EEG and EMG Services

Outpatient EEG
An Outpatient EEG, or electroencephalogram, records the electrical activity of the brain. Sensitive monitoring equipment records the activity through electrodes placed on the patient's scalp.

Inpatient EEG
An Inpatient EEG, or electroencephalogram, is similar to the outpatient procedure with the exception that it is performed during an inpatient hospital admission, at the patient's bedside.

24-, 48-, 72- or 96-hour Ambulatory EEG
An Ambulatory EEG is similar in application to a routine EEG, with the exception that the patient will be monitored continuously for an extended period of time based on the neurologist's assessment of the patient's symptoms. The electrodes are secured by wrapping the patient's head, the patient is discharged home and scheduled to return within 24-, 48-,72- or 96-hours for removal of the electrodes and downloading of the acquired data. A registered technologist then reviews the data, clips and highlights abnormal sections of the recording to aid the reviewing neurologist in interpreting the data.

Long Term EEG Monitoring with Video
EEG monitoring with video for a prolonged period, provides a correlation of recorded behavior (video) and EEG activity. This test aids in the diagnosis of seizures or non-epileptic attacks. Patients are admitted to an inpatient unit and the length of the monitoring is based on the neurologist's assessments of the patient's symptoms and clinical history. Upon completion of the recording, a registered EEG Technologist reviews and scans the record. While reviewing the technologist clips and highlights abnormal sections of the recording to condense the record to aid the reviewing neurologist in interpreting the data in accordance with ASET protocol.

Electromyography (EMG)
This testing procedure involves testing the electrical activity of muscles and the nerves. A neurologist inserts small needle and/or pin electrodes into muscles to measure electrical activity. Once the electrodes have been placed in the appropriate area, the patient is instructed to contract the muscle.

Surface electrodes are used to test the nerves; this procedure is known as Nerve Conductive. This test is commonly used to evaluate the function and the electrical conduction of the motor and sensory nerves of the human body. This test aids in the diagnosis of the following conditions: peripheral neuropathy, carpal tunnel syndrome, ulnar neuropathy, Guillain-Barre syndrome, facioscapulohumeral muscular dystrophy, and spinal disc herniation
