Neurologic Examination Demonstrating Speech-activated Myoclonus. The patient has moderate-severe retrocollis and mild laterocollis to the left, with irregular hyperkinetic head and neck movements during attempted head rotation, consistent with superimposed cervical action myoclonus. Myoclo-nus can also be seen affecting the face and arms. Spontaneous speech is relatively normal in this video segment. While reading, the patient’s speech is frequently interrupted by synchronous myoclonus involving the neck, orbicularis oculi, and vocal musculature.
