The exam contains two types of questions- written and video. Both portions are multiple choice.
Currently, the technique or interpretation of auditory,visual, and somatosensory evoked potentials is not tested on the examination.
The video portion tests the candidate's ability to identify electrical potentials recorded with standard needle electrodes. Information regarding gain, amplitude, and filter settings will be provided. There may be more than one question for a video waveform segment.
Candidates are asked to identify and describe (through multiple choice questions) the characteristics of:
Motor unit action potentials: amplitude, duration, number of phases, stability, recruitment, and firing patterns.
Spontaneous activity: fibrillation potentials, positive sharp waves, fasciculation potentials, myotonic discharges, biphasic endplate activity, monophasic endplate activity, myokymic discharges, complex repetitive discharges, cramp discharges, and neuromyotonic discharges.
Video questions may also contain segments which test the candidate's ability to identify nerves, major muscles, kinesiologic relationships, and physical examination findings potentially encountered during an electrodiagnostic medicine evaluation.
The results of all questions are combined to produce a single score. The scores on individual subsections will not be separately considered in determining the pass/fail status of the candidate.
