Conditions

Neck Pain

Brief summary

A total of 30 patients aged 18-65 years who present with chronic non-specific neck pain and 30 healthy volunteers will be included in the study. Patients with symptoms persisting for at least 3 months will be eligible for inclusion. Necessary information will be provided to all participants, and informed consent will be obtained. To assess pain severity before treatment, participants will be asked to rate their complaints using the Visual Analog Scale (VAS), a linear scale for pain assessment. The Neck Disability Index will be used to determine the level of disability. The Jaw Functional Limitation Scale-20 (JFLS-20), Patient Health Questionnaire-9 (PHQ-9), Patient Health Questionnaire-15: Physical Symptoms, Generalized Anxiety Disorder-7 (GAD-7), and the Oral Behaviors Checklist-included in Axis 2 of the DC/TMD form developed for evaluating temporomandibular joint dysfunction-will be used to assess patients' psychosocial characteristics and parafunctional habits. Additionally, masseter muscle thickness will be evaluated using ultrasonographic measurement.

Design outcomes

Primary

MeasureTime frameDescription
Masseter Muscle Thickness0 dayMeasured using ultrasonography, with values interpreted in relation to clinical findings. No fixed score range; thickness is recorded in millimeters.

Secondary

MeasureTime frameDescription
Neck Disability Index0 dayA questionnaire used to evaluate the level of disability related to neck pain, with higher scores reflecting greater disability. Score range: 0-100.
Patient Health Questionnaire-9 (PHQ-9)0 dayA scale measuring the severity of physical symptoms, where higher scores represent greater somatic symptom burden. Score range: 0-30.
Visual Analog Scale (VAS)0 dayA linear scale used to assess pain severity, where higher scores indicate more severe pain. Score range: 0-10.
Jaw Functional Limitation Scale-20 (JFLS-20)0 dayA tool used to evaluate functional limitations of the jaw, where higher scores indicate greater impairment. Score range: 0-100.
Oral Behaviors Checklist0 dayA questionnaire used to identify parafunctional oral habits, with higher scores reflecting more frequent parafunctional activities. No predefined score range; higher scores indicate greater frequency.
Generalized Anxiety Disorder-7 (GAD-7)0 dayA scale used to assess anxiety levels, with higher scores indicating more severe anxiety symptoms. Score range: 0-21.
