To better define the clinical characteristics of oromandibular dystonia, we aimed to study voice, speech and swallowing disorders in idiopathic oromandibular We planned to include consecutive patients followed in Lille Movement disorders department for idiopathic oromandibular dystonia and matched, healthy control subjects. Voice and speech disorders had to be assessed with the phonetic analysis, perceptive analysis and motor examination modules of the "Batterie d'Evaluation Clinique de la Dysarthrie" (Clinical Evaluation of Dysarthria), the Grade, Rough, Breathy, Asthenic, Strained scale, and a computer recording. Activities of daily living had to be assessed with the Oromandibular Dystonia Questionnaire, the Voice Handicap Index and the Deglutition Handicap Index.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
