An interventional study of Manual Therapy in Temporomandibular Joint Dysfunction, sponsored by Bahçeşehir University. Completed at 1 site in Turkey. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2023-02-21.
Sponsored by Bahçeşehir University · Not applicable, Interventional, and Treatment
Individuals with temporomandibular joint dysfunction (TMD) may experience changes in muscle activation as a result of symptoms such as pain and limitation of movement. The aim of this study is to examine the efficacy of manual therapy electromyographically in patients with TMD.
TMD is a common condition in the community. It may occur due to factors such as trauma, stress, occlusal disorders. Symptoms include pain, limitation in mouth opening, joint voice, postural and psychosocial disorders. TMD/RDC diagnostic criteria are used in the classification of TMD, and accordingly, it is stated that it may originate from the joint, disc and chewing muscles. In the treatment, conservative treatments such as patient education, manual therapy and exercises are applied first.
Manual therapy is an effective physiotherapy method on pain and muscle dysfunctions in musculoskeletal problems. In our study, electromyographic changes of masticatory muscles will be examined by applying manual treatment to the masticatory muscles and cervical region in myofascial TMD patients according to TMD/RC.

Exclusion Criteria:
Upper cervical spine mobilization Posterior-anterior mobilization of the fifth cervical vertebra Suboccipital inhibition Suboccipital mobilization Trigger point application to my masseter, temporal and sternocleidomastoid muscles Intraoral and extraoral myofascial release Intraoral sphenopalatine ganglion technique TMJ mobilization Massage for chewing muscles The 45-minute treatment program, which includes applications including the techniques above, will be applied to the patients randomly assigned to the study group once a week for a total of 4 weeks.The changes in muscle activity of the masseter and anterior temporalis bilaterally will be recorded with EMG.
Other: Manual Therapy
Patients assigned to the control group randomly will be re-evaluated 4 weeks after their initial evaluation. No intervention will be applied during this period. After 4 weeks, when the patients are re-evaluated, they will be directed to the appropriate treatment.

Visual Analogue Scale (VAS)
A Visual Analogue Scale (VAS) is one of the pain rating scales used for the first time in 1921 by Hayes and Patterson. It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms.
Time frame: Change from initial assessment to 4 weeks after initial assessment.
Electromyography (EMG)
Electromyography (EMG) is the most objective and reliable method available for imaging muscle function and efficiency, which is done by identifying their electrical potentials. In global surface electromyography (sEMG), surface electrodes are located on the surface of the skin, and it detects superimposed motor unit action potentials from many muscle fibers
Time frame: Change from initial assessment to 4 weeks after initial assessment.
Pain Pressure Threshold (PPT)
Pain pressure threshold (PPT) is used to measure deep muscular tissue sensitivity. The test determines the amount of pressure over a given area in which a steadily increasing nonpainful pressure stimulus turns into a painful pressure sensation. A varying pressure is applied from 0.5 to 1 kg/sec in a perpendicular direction relative to the muscle.
Time frame: Change from initial assessment to 4 weeks after initial assessment.
Maximum Mouth Opening (MMO)
Maximal opening of mouth is described as the greatest distance between incisal edge of maxillary central incisor to the incisal edge of mandibular central incisor, when the mouth is opened as wide as possible painlessly or as the inter incisal distance plus the overbite. Clinical measurement of normal range of Maximum Mouth Opening (MMO) is an important diagnostic criterion for evaluation of stomatognathic system, especially for those with temporomandibular dysfunctions.
Time frame: Change from initial assessment to 4 weeks after initial assessment.
TAMPA
The original Tampa Scale of Kinesiophobiais (TSK) was first developed in 1991 by R. Miller, S. Kopri, and D. Todd. TSK is 12 items a self-reporting questionnaire based on evaluation of fear of movement, fear of physical activity, and fear avoidance. The questionnaire using 4 points to assess that are based on; the model of fear-avoidance, fear of work-related activities, fear of movement, and fear of re-injury.
Time frame: Change from initial assessment to 4 weeks after initial assessment.
Functional Limitation Scale of the Jaw-8
It is a scale used to evaluate the functionality of the individual's jaw joint in the last month. It consists of 8 items, where the number '0' indicates 'no restriction' and the number '10' indicates 'serious restriction'. By taking the average of the answers given, the functionality restriction is calculated.
Time frame: Change from initial assessment to 4 weeks after initial assessment.
Hospital Anxiety Depression Scale (HADS)
The Hospital Anxiety Depression Scale (HADS) includes two subscales, seven of which measure anxiety (odd numbers) and seven (even numbers) depression, which are used to determine the depression and anxiety levels of individuals, and a total of 14 questions. Each question is scored between 0-3 points. While the minimum score that can be obtained from the depression and anxiety subscales is 0, the maximum score is 21. According to the scores obtained from the subscales, the depression and anxiety status of the individuals are evaluated as normal/no symptoms (0-7 points), borderline abnormal/suspicious (8-10 points), and abnormal/definite (11-21 points).
Time frame: Change from initial assessment to 4 weeks after initial assessment.
