About this study
Official title: 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Cervical Posture Angles
Measured: Baseline (at a single assessment point)
Cervical and Temporomandibular Joint Pain Intensity
Description: Will be evaluated using a 10-cm Visual Analog Scale (VAS; 0 = no pain, 10 = worst imaginable pain) for neck pain and TMJ pain (at rest, during activity, and while chewing).
Measured: Baseline (at a single assessment point).
Cervical Range of Motion (CROM)
Description: Will be evaluated in degrees for active cervical flexion, extension, bilateral lateral flexion, and bilateral rotation using the CROM (Cervical Range of Motion) device.
Measured: Baseline (at a single assessment point).
Mandibular Range of Motion
Description: Will be measured in millimeters (mm) using a digital caliper and ruler for maximum mouth opening, right/left lateral movements, and protrusion.
Measured: Baseline (at a single assessment point).
Text Neck Posture Classification
Text neck posture will be assessed using both self-reported perception and standardized photographic analysis.
Measured: Baseline (at a single assessment point).
Secondary outcomes (4)
Temporomandibular Joint Dysfunction Severity
Description: Will be evaluated using the Turkish-validated Fonseca Questionnaire (10 items, total score 0-100; higher scores indicate greater TMD severity).
Measured: Baseline.
Cervical Joint Position Sense (JPS)
Description: Will be evaluated in degrees using the CROM device across flexion-extension, lateral flexion, and rotation planes to measure absolute error from a target angle
Measured: Baseline
Static Balance
Description: Will be measured in seconds with eyes open and eyes closed on a firm surface.
Measured: Baseline.
Dynamic Balance Assessment using the Y Balance Test
Measured: Baseline

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cervical Posture Angles (time frame: Baseline (at a single assessment point)). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
