Study summary

The goal of this randomized clinical trial is to investigate the effectiveness of Manual Therapy Based on the Fascial Distortion Model (FDM) on the cervical spine by comparing it with Core Stabilization Training (CST) or Control in individuals with temporomandibular disorders. The main questions it aims to answer are:

Is the effectiveness of the addition of FDM-based Manual Therapy to conventional therapy different from the addition of CST or control? Is the effectiveness of the addition of CST to conventional therapy different from the addition of FDM or control? All participants in the intervention groups will be given eight-week conventional therapy (Rocabado Exercises and Patient Education) in addition to FDM-based Manual Therapy or CST. Participants in the control group will not be given any therapy during the study.

Neck pain intensity, hand grip strength, head posture, cervical muscle performance, cervical range of motion (function), disability, and quality of life will be assessed.

Read the detailed description

Interventions are needed to address neck pain intensity, hand grip strength, head posture, cervical muscle performance, cervical range of motion (function), disability, and quality of life in individuals with temporomandibular disorder (TMD). This study aims to examine the effectiveness of Fascial Distortion Model-based Manual Therapy compared to Core Stabilization Training or Control in individuals with TMD over an 8-week period. Individuals with TMD will be randomized into Group 1 (Fascial Distortion Model-based Manual Therapy, Rocabado Exercises, and Patient Education), Group 2 (Core Stabilization Training, Rocabado Exercises, and Patient Education), or Group 3 (Control). Rocabado Exercises and Patient Education will be implemented as a home program for 8 weeks, while Fascial Distortion Model-based Manual Therapy and Core Stabilization Training will be conducted once a week in a clinical setting. Neck pain intensity will be assessed using the Graded Chronic Pain Scale (Revised) and the Short-Form McGill Pain Questionnaire. Hand grip strength and head posture will be assessed using a hand dynamometer and lateral photography, respectively. The Functional Strength Testing of the Cervical Spine and cervical range of motions will be used to assess cervical muscle performance and function, respectively. Disability and quality of life will be evaluated using the Neck Disability Index and the Cognitive Exercise Therapy Approach-Biopsychosocial Questionnaire. All outcomes will be measured at baseline and end of the study, while neck pain intensity will also undergo intermediate assessments (2nd, 4th, and 6th weeks).

  2. Cervical muscle performance

    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.

    Time frame: From enrollment to the end of treatment at 8 weeks
