Cannabis-induced propriospinal myoclonus.
We report on a case of a 25-year-old woman with clusters of myoclonus induced by a single exposure to inhaled cannabis. Investigations excluded a structural abnormality of the spine. Multi-channel surface EMG with parallel frontal EEG recording confirmed the diagnosis of propriospinal myoclonus.
