e aim of the present study was to evaluate the e ciency of high intensity laser and ultrasound therapy in patients who were diagnosed with lumbar disc herniation and who were capable of performing physical exercises. 65 patients diagnosed with lumbar disc were included in the study. e patients were randomly divided into three groups: Group 1 received 10 sessions of high intensity laser to the lumbar region, Group 2 received 10 sessions of ultrasound, and Group 3 received medical therapy for 10 days and isometric lumbar exercises. e e cacy of the treatment modalities was compared with the assessment of the patients before the therapy at the end of the therapy, and in third month a er the therapy. Comparing the changes between groups, statically signi cant di erence was observed in MH (mental health) parameter before treatment between Groups 1 and 2 and in MH parameter and VAS score in third month of the therapy between Groups 2 and 3. However, the evaluation of the patients a er ten days of treatment did not show signi cant di erences between the groups compared to baseline values. We found that HILT, ultrasound, and exercise were e cient therapies for lumbar discopathy but HILT and ultrasound had longer e ect on some parameters.
