Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	Change from initial assessment to 4 weeks after initial assessment.
Secondary	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	Change from initial assessment to 4 weeks after initial assessment.
Secondary	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.	Change from initial assessment to 4 weeks after initial assessment.
Secondary	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.	Change from initial assessment to 4 weeks after initial assessment.
Secondary	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.	Change from initial assessment to 4 weeks after initial assessment.
Secondary	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.	Change from initial assessment to 4 weeks after initial assessment.
Secondary	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).	Change from initial assessment to 4 weeks after initial assessment.
