The objective of this study will be to verify the additional effect of Pain Neuroscience Education, Motor Imagery and Action Observation on primary outcomes pain intensity and craniofacial pain and disability in patients with chronic temporomandibular disorders (TMD). The secondary outcomes will be pressure pain threshold, temporal summation, conditioned pain modulation, central sensibilization, pain catastrophizing, kinesiophobia. This study will be a doble-blinded randomized clinical trial comprising a sample of 50 participants with orofacial pain of both genders and aged between 18 and 60 years. Subjects will undergo a screening process to identify those presenting a diagnosis of painful TMD confirmed by the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), and then they will be randomized into two groups (G1: Occlusal Splint, Counselling and Jaw and Neck Exercises vs. (G2: Occlusal Splint, Jaw and Neck Exercises plus Pain Neuroscience Education, Motor Imagery and Action Observation). These volunteers will be recruited from the Alisos Group Dentistry Clinic and University of Gran Rosario, (Rosario, Argentina). All patients will wear an occlusal splint designed by dentists. The interventions will be administered twice a week for 5 weeks by a single therapist. Subsequently, patients will be given instructions to perform the exercises at home for 5 weeks. Primary and secondary outcomes will be measured at baseline, 6 weeks and 12 weeks, and at 3 months after the end of treatment (follow-up). All the evaluations will be performed by a blinded physiotherapist.
