Relationship Between Upper Cervical Mobility and Temporomandibular Joint Range of Motion in Patients With Temporomandibular Disorders

Upper cervical spine mobility plays a crucial role in temporomandibular joint (TMJ) function. This observational study investigates the relationship between upper cervical spine mobility and TMJ range of motion in patients diagnosed with temporomandibular disorders (TMD). Cervical hypomobility may restrict mandibular movement and contribute to TMJ dysfunction through shared biomechanical and neuromuscular mechanisms.
