The spectrum of orolingual tremor--a proposed classification system.

Orolingual tremors include tremors of the jaw, tongue, pharynx, and face. There is currently no accepted classification scheme for such tremors. A proper classification scheme for orolingual tremors should aid in providing more accurate diagnoses and permit future research studies assessing important aspects such as pathogenesis or novel therapies using more uniformly defined and characterized populations. In this review, we propose a classification system for orolingual tremor based on the consensus statement of the Movement Disorder Society on tremor. We also present cases of orolingual tremor and include these cases in the classification system. 2007 Movement Disorder Society
