The Effect of Improvement of Temporomandibular Joint Movement Restriction using the Kaltenborn-Evjenth Orthopedic Manipulative Therapy

Kaltenborn-Evjenth 정형도수치료가 측두하악관절 운동제한 개선에 미치는 효과

The purpose of this study is to prove the efficacy of the Kaltenborn-Evjenth Orthopedic Manipulative Therapy and the Conventional Physical Therapy that influence changes in pain and range of motion when those therapies are applied to patients with temporomandibular pint movement restriction. The subjects of the study were 30 randomly selected patients who had been diagnosed with temporomandibular pint movement restriction and had endured pain for more than two weeks. These patients had visited one of three hospitals in Pyongchon 00 Hospital. The subjects were divided into two groups with 15 patients each. The Kaltenborn-Evjenth Orthopedic Manipulative Therapy was applied to one group and the Conventional Physical Therapy was applied to the other group, once a day for three days. Then, the pain perception degree was measured by using the Visual Analogue Scale(VAS) and a digital device(Absolute Digimatic) measured the range of motion for each group. The average and standard errors were calculated for each measured items and a paired t-test was used for identifying significance in the differences in the pain perception degree and the range of motion between the two groups according to therapy. The significant level was set as ${\alpha}=0.05$. The changes in the pain perception degree were statistically significant in both groups; however, the group that received Kaltenborn-Evjenth Orthopedic Manipulative Therapy(KE-Group) showed more significant changes in a decrease in the pain perception degree than did the group that received the Conventional Physical Therapy(CPT-Group). Both groups showed significant results regarding changes in the range of motion: however, the KE-Group showed more of a significant difference in the average of the range of motion than did the CPT-Group(p<0.001). Comparing the changes in the range of motion between the two groups, the KE-Group showed a significant result which means that the KE-Group had a higher therapy effect than did the CPT-Group(p<0.05). Based on the results of this study, we found that the Kaltenborn-Evjenth Orthopedic Manipulative Therapy decreased pain and increased the range of motion. With such findings, we expect that the Kartenborn-Evjenth Orthopedic Manipulative Therapy can be used as an effective treatment method for patients with tempomrnandibular pint movement restriction and that the treatment period can be reduced with this therapy as well.
