Description

Interventions are needed to address head posture, cervical and temporomandibular joint range of motion, cervical muscle performance, pain intensity, pressure pain thresholds, temporomandibular disorder severity, disability, dysfunction, health-related quality of life, kinesiophobia, and central sensitization in individuals with temporomandibular disorder (TMD). This study aims to examine the effectiveness of Manual Therapy Based on the Fascial Distortion Model in individuals with TMDs compared to sham control over a 4-week period. Individuals with TMD will be randomized into Group 1 (Fascial Distortion Model-based Manual Therapy) or Group 2 (Sham Control). Interventions will be conducted once a week in a clinical setting. Head posture will be measured by lateral photogrammetry, cervical range of motion will be measured by an inclinometer, temporomandibular range of motion will be measured by a vernier caliper, cervical muscle performance will be measured by Cervical Spine Functional Strength Test, and pressure pain threshold will be measured by an algometer. Pain intensity will be assessed using the Graded Chronic Pain Scale (Revised) and the Short-Form McGill Pain Questionnaire. TMD severity will be assessed using the Fonseca Anamnestic Index. Mandibular Function Impairment Questionnaire will be used to assess dysfunction. Disability will be evaluated using the Craniofacial Pain and Disability Inventory. Health-related quality of life will be assessed using Short Form-36. Kinesiophobia will be assessed with the Tampa Kinesiophobia Scale; central sensitization will be assessed with the Central Sensitisation Inventory.

All outcomes will be measured at baseline and end of the study, while pain intensity and pressure pain thresholds will also undergo intermediate assessments (2nd and 3rd week).
