About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
University students aged between 18 and 24 years,
Group 1: Individuals with level 3 or level 4 text neck posture based on the self-reported posture assessment diagram,
Group 2: Individuals with level 1 or level 2 text neck posture based on the self-reported posture assessment diagram,
Being physically and mentally eligible to participate in the study,
Disqualifiers
History of cervical spine surgery,
Ongoing orthodontic treatment,
Receiving medical treatment related to the neck or jaw region within the last 3 months,
Exposure to trauma related to the neck or jaw region within the last 3 months,
Trial population
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.

Trial outcomes
Primary outcomes
1
Cervical Posture Angles
Time frame
Baseline (at a single assessment point)2
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).
Time frame
Baseline (at a single assessment point).3
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.
Time frame
Baseline (at a single assessment point).4
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.
Time frame
Baseline (at a single assessment point).Secondary outcomes
1
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).
Time frame
Baseline.2
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
Time frame

Static Balance
Description: Will be measured in seconds with eyes open and eyes closed on a firm surface.
