Given the anatomical, biomechanical, and functional connections between the stomatognathic system and the cervical region, prolonged altered posture may contribute to TMJ dysfunction, pain, and altered physical metrics. Participants are categorized into two groups based on photographic and self-reported text neck severity (levels 3-4 for text neck vs. levels 1-2 for non-text neck) and evaluated across multiple physical parameters, including craniovertebral and cervicothoracic angles, active cervical and mandibular range of motion, cervical joint position sense, neck and TMJ pain intensity via Visual Analog Scale, TMJ dysfunction severity using the Turkish-validated Fonseca Questionnaire, static balance via the single-leg stance test, and dynamic balance via the Y Balance Test.",[69,70,71],"Text Neck Syndrome","Temporomandibular Joint Disorders","Postural Balance","NOT_YET_RECRUITING","2026-09-26",{"date":75,"type":76},"2026-10-01","ACTUAL",{"date":75,"type":65},{"date":79,"type":65},"2026-12-28",{"name":51,"class":6}]
