Popis: A 12-year-old girl presented with a 2-year history of rhythmic ear clicks. She was born 7 weeks premature with caesarean without fetal distress and had a normal psychomotor development. A strabismus was corrected by surgery. The clicks started concurrently with an acute infectious sinusitis. These involuntary clicks were not bothersome and stopped during sleep. They were present every day with a fluctuating intensity. Free intervals shorter than 2 days may rarely occur. She had no particular tricks to control the clicks, and no provoking factors were identified. Examination revealed isolated continuous rhythmic bilateral and symmetrical brisk movements of the soft palate (see Video 1). Brain MRI was normal with no hypertrophy of the inferior olive. Because the movements of the soft palate seemed quite irregular, she was referred to our neurophysiology department to determine precisely the palatal tremor (PT) frequency and to perform frequency entrainment trials in order to examine the psychogenic hypothesis.
