Comparison of Cervical and TMJ Parameters in Young Adults With and Without Text Neck Syndrome
Comparison of Physical Parameters Related to the Cervical Region and Temporomandibular Joint in Young Individuals With and Without Text Neck Syndrome: A Cross-Sectional Study
The aim of this cross-sectional study is to compare temporomandibular joint (TMJ) and cervical spine parameters between young university students aged 18-30 years with and without text neck syndrome, a modern overuse condition caused by prolonged digital device use and repetitive forward head flexion. 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.

연구 인구
The study population consists of young adult university students aged 18 to 30 years recruited from a university campus environment. Participants will be sampled from healthy undergraduate and graduate students who routinely use digital devices (such as smartphones and tablets) in their daily academic and personal activities.
