This cross-sectional study will examine the relationship between mandibular dysfunction, cervical joint position sense, craniovertebral angle, neck pain, and temporomandibular dysfunction (TMD) severity. TMD severity, mandibular function, cervical proprioception, craniovertebral angle, and neck pain history will be assessed using standardized clinical tools and questionnaires. The study will evaluate the associations between these variables and determine the factors that may predict TMD severity.
Fonseca Anamnestic Index score > 15
aged 18 years and older
Received medical, orthodontic, or physiotherapy treatment targeting the temporomandibular joint and/or cervical region within the past six months
used analgesic, anti-inflammatory, or muscle relaxant medications
history of cervical spine or cranio-cervical surgery or major trauma
a history of facial or TMJ trauma, TMJ subluxation or dislocation
Adults aged 18 years or older with a Fonseca Anamnestic Index (FAI) score of 20 or higher who gave written consent were included. Participants were people with jaw (TMJ) and/or neck complaints. People were excluded if they had recent treatment (last 6 months) for the jaw or neck, used pain or muscle relaxant drugs, had previous neck or jaw surgery or major trauma, jaw dislocation or subluxation, missing teeth or dental prostheses, or neurological, rheumatologic, or systemic inflammatory diseases.

Assessments
Other interventionNo intervention was applied.
Temporomandibular Dysfunction Severity
TMD severity will be assessed using the Fonseca Anamnestic Index, which evaluates the severity of temporomandibular dysfunction symptoms. It is a 10-item self-report questionnaire. Each item is scored as "Yes" (10 points), "Sometimes" (5 points), or "No" (0 points), with a total score calculated by summing all items.
Cervical Extension Joint Position Sense
Cervical extension joint position sense will be assessed in a sitting position using an Acumar dual digital inclinometer. Participants will be asked to actively move their neck to 30° of cervical extension, memorize the target position, and then reproduce the same angle. The procedure will be repeated three times, and the average absolute error will be recorded.
Cervical Flexion Joint Position Sense
Cervical flexion joint position sense will be assessed in a sitting position using an Acumar dual digital inclinometer. Participants will be asked to actively move their neck to 30° of cervical flexion, memorize the target position, and then reproduce the same angle. The procedure will be repeated three times, and the average absolute error will be recorded.
Cervical Lateral Flexion Joint Position Sense
Cervical lateral flexion joint position sense will be assessed in a sitting position using an Acumar dual digital inclinometer. Participants will be asked to actively move their neck to 30° of lateral flexion, memorize the target position, and then reproduce the same angle. The procedure will be repeated three times, and the average absolute error will be recorded.
Cervical Rotation Joint Position Sense
Cervical rotation joint position sense will be assessed in a supine position using an Acumar dual digital inclinometer. Participants will be asked to actively rotate their head to 50° of cervical rotation, memorize the target position, and then reproduce the same angle. The procedure will be repeated three times, and the mean absolute error will be recorded.
