Temporomandibular Joint Dysfunction: Clinical Evaluation and Physiotherapeutic Approaches

Temporomandibular joint disorders (TMDs) refer to a range of conditions that impact the temporomandibular joint, masticatory musculature, and related structures. They are the significant cause of orofacial pain and functional limitations, impacting quality of life and daily function. A thorough comprehension of temporomandibular joint anatomy and biomechanics is crucial to achieve accurate diagnosis and effective physiotherapeutic management. This paper provides a comprehensive overview of TMDs, including their anatomical and biomechanical foundations, current diagnostic and evaluation techniques, and emerging physiotherapy interventions. This narrative review was conducted to explore recent developments for evaluation, diagnosis, and management of temporomandibular joint disorders (TMDs), with a focus on conservative and physiotherapy-based interventions. The TMJ is a complex synovial joint with unique biomechanical features that allow for both hinging and gliding motions. Dysfunction in this joint often results from musculoskeletal imbalances, trauma, or parafunctional habits. Evaluation of TMD includes clinical assessment (e.g., range of motion, joint sounds, palpation), validated outcome measures (e.g., JFLS, OHIP-TMD), and imaging. Physiotherapy interventions—such as manual therapy, muscle energy techniques (MET), soft tissue mobilization, neuromuscular re-education, and patient-specific exercise programs—have shown significant improvements in pain reduction and functional outcomes. New perspectives include tele-rehabilitation and integration of digital tools for objective assessment and monitoring. Early and accurate diagnosis combined with a multidisciplinary physiotherapy approach is crucial for effective TMD management. Continued research and clinical innovation are essential to refine physiotherapeutic protocols and incorporate technology-driven care tailored to individual patient needs.
