About

Temporomandibular Disorders (TMD) are a collection of musculoskeletal disorders which affect the masticatory structures and have a multifactorial etiology. A biopsychosocial approach is recommended for the management of these disorders including different interventions like exercise, manual therapy and pain education. The aim of this study is to compare the effect of a full dosage mode pain science education program (2 initial sessions of 45 minutes) versus a fractioned dosage format (6 sessions of 15 minutes) combined with manual therapy and orofacial exercises on primary outcomes - pain intensity and disability - and secondary outcomes - mandibular range of motion, pain-related self-efficacy, kinesiophobia, global perception of improvement, empathy, knowledge about pain neuroscience, beliefs about pain, exercise adherence, and catastrophizing - in patients with chronic painful TMD. This study will be a randomized controlled trial with a sample of 148 participants. Individuals will undergo a screening process to identify those with TMD diagnosis according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), aged 20 to 60 years, of both genders, and then the volunteers will be randomized into two groups (G1: Full dosage mode pain science education program + Manual therapy/orofacial and neck motor exercises vs. G2: Fractioned dosage mode pain science education program + Manual therapy/orofacial and neck motor exercises). These volunteers will be recruited in the city of São Carlos, SP. The intervention will take place twice a week for 8 weeks, administered by a single therapist, each session lasting 1 hour. The primary outcomes will be pain intensity and disability, assessed using the numerical pain rating scale and the Craniofacial Pain and Disability Inventory (CFP-DI), respectively, and the secondary outcomes will be mandibular range of motion, pain-related self-efficacy, kinesiophobia, global perception of improvement, empathy, knowledge about pain neuroscience, beliefs about pain, exercise adherence, and catastrophizing, assessed using the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD), Global Perceived Effect of Improvement scale, Pain Self-Efficacy Questionnaire (PSEQ), CARE Empathy Scale, and Pain Catastrophizing Scale (PCS). For statistical analysis, a Generalized Estimated Equations considering time and groups as factors will be used. A significance level of p<0.05 will be considered.

148 participants in 2 patient groups

Fractioned Pain Science Education + Manual Therapy + Orofacial and Neck Exercises
Active Comparator group
Description:
All participants in this arm will initially receive six sessions in which a workshop on PSE will be administered and discussed. A power-point presentation with metaphors and animated videos will be employed. The PSE program will be held in 6 sessions of 15 minutes each. Two protocols of Orofacial Exercises and Manual Therapy and of Neck Motor Control will be adopted in the present study. The exercises will be administered during six weeks, twice a week. One session will run in the outpatient clinic and the other will be home based. Half of the sessions will consist of orofacial therapy and exercises and the other half neck motor control exercises. Each exercise and technique will be administered 10 times for 10 seconds.

Other: Orofacial and Neck Exercises (ONE)
