Introduction: Clinical presentation of oromandibular dystonia (OMD) is variable that can be further complicated by the presence of temporomandibular disorder (TMD) symptoms. We sought to evaluate variations in the clinical presentation of OMD patients, particularly TMD-related characteristics, in two clinical settings. Methods: In a cross-sectional study design, a Web-based data collection survey was provided to eligible patients with OMD from movement disorder (MD) and oro-facial pain (OFP) clinics. The survey questionnaire was designed to collect information on demographic characteristics, clinical presentation particularly related to TMD, quality of life and treatment outcomes. Validated questionnaires were used when available such as the TMD Pain Screener, EuroQol 5-Dimensions 5-Levels (EQ-5D-5L), Jaw Functional Limitation Scale and Global Rating of Change Scale. Results: Of 53 eligible patients, 31 responded to the survey for a 58% response rate. Forty-eight per cent of patients in the MD clinic and 60% of patients in the OFP clinic reported jaw pain along with involuntary movements. Of those, 90% from the MD group and 83% from the OFP group screened positive with the TMD Pain Screener at the onset of symptoms based on recall. Positive TMD Pain Screener response was observed in about 40% of patients in both clinics within 30 days of questionnaire response. No statistically significant differences were observed between two groups for any measured variables. Conclusion: Patients with OMD have features of TMD, irrespective of the clinical setting in which they seek and receive care. OMD patients from both clinics were similar in terms of clinical presentation, quality of life and treatment outcomes.
