Myoclonus Palatal tremor 2009-09-20T08:50:17Z Previously, PT was known as palatal myoclonus but it was subsequently renamed palatal tremor during the First International Congress of Movement Disorders to acknowledge the continuous and rhythmic nature of the palatal movement. Palatal tremors do not oscillate around a point, unlike any other type of tremor. Palatal tremors can have huge variability in frequency, unlike other commonly-described tremors. UMLS:C0030214 Palatal tremor (PT) is an involuntary, rhythmic and oscillatory movement of the soft palate. PT is a rare type of tremor involving the soft palate. It can be unilateral or bilateral.
