Brief Summary

The aim of the study was to investigate the effectiveness of Manual Therapy Based on the Fascial Distortion Model in individuals with temporomandibular disorders compared to sham control. Individuals diagnosed with temporomandibular disorder will be randomly assigned to groups as Group 1 (Manual Therapy Based on Fascial Distortion Model) and Group 2 (Sham Control). 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 will be assessed.

Detailed 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).

Primary Outcome Measures
NameTimeMethod
Head postureFrom enrollment to the end of treatment at 4th week

Lateral photogrammetry according to Eye-Tragus-Horizontal Angle, Pogonion-Tragus-C7 Angle, Tragus-C7-Horizontal Angle, Tragus-C7-Shoulder Angle, and Shoulder-C7-Horizontal Angle.

Cervical range of motionsFrom enrollment to the end of treatment at 4th week

Inclinometric measurements based on flexion, extension, lateral flexions, and rotations.

Temporomandibular range of motionsFrom enrollment to the end of treatment at 4th week

Digital vernier caliper measurements based on maximum pain-free mouth opening, maximum possible mouth opening, maximum possible assisted mouth opening, laterotrusions, and protrusion.

Cervical muscle performanceFrom enrollment to the end of treatment at 4th week

The Functional Strength Testing of the Cervical Spine was used to evaluate the cervical muscle performance. This is a test that functionally evaluates cervical muscle strength. Results of this test are assessed as functional, functionally fair, functionally poor, and nonfunctional. Six-to-eight repetitions for the flexion test and 20-25 s holding time for the other tests indicate that the test result is functional. Three-to-five repetitions for the flexion test and 10-19 s holding time for the other tests indicate that the test result is functionally fair. One-to-two repetitions for the flexion test and 1-9 s holding time for the other tests indicate that the test result is functionally poor. Zero repetition for the flexion test and 0 s holding time for the other tests indicate that the test result is nonfunctional. Each test was terminated at onset of pain, and the relevant value was recorded.

Pressure pain thresholdFrom enrollment to the end of treatment at 1st week, 2nd week, 3rd week, and 4th week.

Algometer. Tempormandibular joint, masseter, temporalis anterior, suboccipital muscle, trapezius, lateral epicondyle for both side.

Pain intensity in the last weekFrom enrollment to the end of treatment at 1st week, 2nd week, 3rd week, and 4th week.

Short-Form McGill Pain Questionnaire. Minimum and maximum values are 0 and 3 points, respectively. Higher scores mean a worse outcome.

Chronic pain intensityFrom enrollment to the end of treatment at 1st week, 2nd week, 3rd week, and 4th week.

Graded Chronic Pain Scale (Revised). Scoring: Grade 1=mild, Grade 2=bothersome, Grade 3=high impact chronic pain. Higher scores mean a worse outcome.

Temporomandibular disorders severityFrom enrollment to the end of treatment at 4th week

Fonseca Anamnestic Index. Minimum and maximum values are 0 and 10 points, respectively. Higher scores mean a worse outcome.

DysfunctionFrom enrollment to the end of treatment at 4th week

Mandibular Function Impairment Questionnaire. Minimum and maximum values are 0 and 4 points, respectively. Higher scores mean a worse outcome.

DisabilityFrom enrollment to the end of treatment at 4th week

Craniofacial Pain and Disability Inventory. Minimum and maximum values are 0 and 3 points, respectively. Higher scores mean a worse outcome.

Health-related quality of lifeFrom enrollment to the end of treatment at 4th week

Short Form-36. Its subdomains are physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health.

KinesiophobiaFrom enrollment to the end of treatment at 4th week

Tampa Kinesiophobia Scale for Temporomandibular Disorders. Minimum and maximum values are 1 and 4 points, respectively. Higher scores mean a worse outcome.

Central sensitizationFrom enrollment to the end of treatment at 4th week

Central Sensitisation Inventory. Minimum and maximum values are 0 and 4 points, respectively. Higher scores mean a worse outcome.

Present pain intensityFrom enrollment to the end of treatment at 1st week, 2nd week, 3rd week, and 4th week.

Visual Analog Scale. Minimum and maximum values are 0 and 10 cm, respectively. Higher scores mean a worse outcome.

Present pain intensity (ordinal)From enrollment to the end of treatment at 1st week, 2nd week, 3rd week, and 4th week.

Present pain intensity scale of McGill Pain Questionnaire. Minimum and maximum values are 0 and 5 points, respectively. Higher scores mean a worse outcome.

Pain intensity in the last week (ordinal)From enrollment to the end of treatment at 1st week, 2nd week, 3rd week, and 4th week.

Numeric Pain Rating Scale. Minimum and maximum values are 0 and 10 points, respectively. Higher scores mean a worse outcome.
