Introduction: Temporomandibular disorders (TMD) are the second most common cause of chronic pain in the human musculoskeletal system. The triad of symptoms of TMD includes: pain within the temporomandibular joint (TMJ), limitation of its mobility and crepitations. The aim of the study was to present the methods of physiotherapy and to assess its effectiveness in patients with hypomobility of temporomandibular joints.

Material and Methods: 44 patients (40.2 ± 10.6 years) were examined for signs of TMD using the Manual Functional Analysis of masticatory system (MFA) questionnaire due to DC/TMD. In the above group, 20 patients showed hypomobility of TMJs and myofascial pain. They underwent a 3-week phy-siotherapy consisting of manual therapy and exercises. In the study group, linear measurements of TMJs mobility and palpation of selected masticatory muscles were performed. Pain was assessed before and after 3 weeks of therapy according to Numerical Rating Scale (NRS). Statistical processing of the data was done with STATISTICA 13 and was conducted considering significance at a p-value <0.05.

Results: Significant improvement in TMJ’s mobility, which increased on average by 6.6 mm (p = 0.0005) and reducing of pain, a decrease of 3 points on average on the NRS Scale (p = 0.00002) were achieved.

Conclusions: The applied physiotherapy algorithm, including manual therapy and exercises of mas-ticatory muscles, is effective in the case of improvement TMJ’s range of motion and reduction of pain in patients with hypomobility of TMJ’s.

TMD is a disease within the masticatory system that increases its reach among the society every year in the third and fourth decade of life. The etiology of TMD is complex and it is often difficult to establish the cause in a specific case. The aim of the study was to determine the impact of TMD on pathomorphological changes within the temporomandibular joints, evaluated in USG examinations and evaluation the assessment of differences in the number of pathological changes between various forms of TMD.
Material and Methods: The study material included a group of 386 patients, both sexes, aged 20 to 46 years, who came for prosthetic treatment due to symptoms of TMD. Ultrasound examination of the temporomandibular joints supplemented the clinical diagnosis of TMD in all the subjects. Axis I of the DC/TMD were used.
Results: Group I included 116 women and 89 men, group II consisted of 102 women and 79 men. Pathological morphological changes in the temporomandibular joints were found in all the examined patients. The changes in soft tissue structures were significantly increased in group II, but numerous pathomorphological changes were also present in the group of patients with the muscle form of TMD.
Conclusion: The results of the conducted studies with the use of USG temporomandibular joints revealed numerous pathomorphological changes within the temporomandibular joints. This indicates the usefulness of the USG examination in additional diagnostic tests in the group of patients with TMD.
