Psychosomatic Symptoms in Patients With Myofascial Pain and Temporomandibular Joint Dysfunction

Temporomandibular joint disorder poses an intricate etiology. Biomechanical, neuromuscular and psychosocial factors may contribute to the disorder among which psychological and psychosocial disturbances have shown strong direct or indirect contribution to the disease especially when the pain is of muscular origin.

Temporomandibular disorders (TMDs) are defined as the group of musculoskeletal and neuromuscular conditions that involves temporomandibular joint (TMJ), masticatory muscles, and their associated structures (1). Clinically, TMDs are characterized by jaw pain, mandibular movement limitation, joint sounds, and often referred pain in the head, neck, or shoulders region (2). The myofascial pain, a subtype of TMD, is most prevalent condition and it accounts for approximately 50% of all TMD cases in clinical settings (3). Although it's a prevalent condition, but its complex aetiology makes it difficult to diagnose (4).
