Evoked Potential Correlation

American Board of Registration of Electroencephalographic and Evoked Potential Technologists, Inc
Oral and Practical Examination for EEG Registration

PART I BAEP/VEP CONCEPTS
PART II SSEP CONCEPTS

03/2008

The Evoked Potential Correlation section evaluates the candidate's ability to 1) recognize and describe normal, abnormal and artifactual patterns in visual (VEP), brainstem auditory (BAEP), and somatosensory (SSEP) median and posterior tibial nerve evoked potentials (EP); 2) correlate clinical history and EP findings; 3) explain the significance and use of electrodes, instrument settings, polarity: 4) explain troubleshooting techniques; 5) calculate voltage and identify and measure obligate waveforms; 6) explain the significance of normative data, visual angle, hearing thresholds, stimulus intensity and polarity as they relate to the American Clinical Neurophysiology Society (ACNS) Guidelines.

Each section will be 60 minutes: Part I will focus on VEP and BAEP, and Part II will be median and posterior tibial nerve SSEP.

The candidate will be asked to label and identify the obligate waveforms for each modality.

The candidate is expected to respond to questions by applying his or her basic knowledge to the situations presented. The expectations for safe and effective performance of the task are outlined in the Evoked Potential Practice Analysis, Domains I and II.

The examination begins as soon as the candidate enters the examination room. The examiners show the candidate a series of evoked potential patterns and associated histories. The examiners ask a variety of questions relating to the pattern. Questions may include the following topics: waveform description, clinical history, artifacts, polarity, filters, montages, troubleshooting, clinical correlation, and measurement calculations. Rulers and calculators will be provided. The candidate is expected to use appropriate terminology when responding to the questions, and must correctly answer the questions to pass the exam. Two examiners are in the room with the candidate through most of the examination, while the Section Director enters the room at random intervals to monitor exam progress.

The patterns presented to the candidate demonstrate normal, abnormal, artifactual patterns or a combination of patterns. The samples are single page, full size and good reproductions of actual evoked potential waveforms.

Each section is scored Pass or Fail based on accepted and published criteria and ACNS Guidelines.
