Basic concept of exercise therapy in TMJ disc derangement without reduction and osteoarthritis of the TMJ

Abstract

TMDs are basically locomotor disorders, and like other locomotor organs, exercise therapy is effective. When performing exercise therapy for TMDs, it is necessary to consider the peculiarities of the TMJ while referring to the concept of exercise therapy for other locomotor organs. The basics of exercise therapy for TMJ disc derangement without reduction and osteoarthritis of the TMJ are to expand the range of motion of the joints and improve fluid circulation by improving joint and masticatory muscle contractions and internal joint disorders. Static stretching of the TMJ is important in exercise therapy to encourage functional recovery and alleviate associated pain. In stretching for the TMJ, it is necessary to consider the stretching direction and improvement with resting for 10 to 60 seconds in the maximum range of motion due to the sliding motion of the mandibular condyle, compression of the posterior tissue of the articular disc, and compression. In addition, as exercise therapy, it is more effective to perform "manual therapy" in combination with "manual therapy" after the patient has received full instruction and practiced "exercise therapy (self-care) performed by the patient himself according to the instructions of the surgeon". It seems to be. As the range of motion of the joint improves, the TMJ including the mandibular condyle morphology may change and the jaw position and occlusal state may change. Therefore, it is also possible to grasp the change in the occlusal state from the first examination. It becomes important. In the future, in order to establish exercise therapy for TMDs, it is necessary to collaborate among multiple disciplines such as physiotherapists and dental hygienists, and to unify terms and procedures.
