Long-term Efficacy of Physical Therapy for TMDs

Study Overview
=================
Brief Summary
-----------------
Physical therapy is one of the initial conservative treatments for TMD. Many studies and previous studies in our department have proved that it can improve the pain, mouth opening and mandibular function of patients with TMD. However, the current research on physical therapy for TMD has a short follow-up period, which cannot prove that the patients' long-term mandibular function has improved, and few studies have analyzed the relevant factors affecting the curative effect. Therefore, this study is intended to adopt a retrospective cohort study to include TMD patients who received physical therapy in our department from 2016.01-2021.12. The patients' pain, joint area noise, mandibular range of motion, mandibular function and other conditions will be followed up by remote telephone or online questionnaire, and the patients' demography, clinical symptoms, pain, oral habits, depression, anxiety, sleep status, head and neck posture and other information will be collected. The multiple regression analysis model will be used to compare and analyze the relevant factors affecting the prognosis of patients, and to intervene in advance the factors that have a significant impact on the prognosis of the disease, so as to improve the treatment effect.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| PE<br>Patient education combined with drug therapy group | Combination Product: Patient education combined with drug therapy<br>* Receive a health education by a specialist therapist, including explaining the anatomy and function of TMJ; Explain the etiology, prognosis, treatment plan and prognosis of TMD; Correct the patients' daily oral habits, such as unilateral chewing, habitual clenching, eating too much hard food, etc; Instruct the patient to understand the rest position of the temporomandibular joint and correct the bad posture of the neck and shoulder. At the same time, corresponding medication should be given, and NSAIDS should be taken orally or externally for patients with pain.<br>|
