Main Article Content
Abstract
Objective: To evaluate the therapeutic efficacy of combining Laser acupuncture, TENS and Exercise therapy in treating primary knee osteoarthritis at the Department of Traditional Medicine, Ba Vi General Hospital in 2025. This study also monitored potential adverse effects of the intervention. Methods and Materials: This was a clinical trial conducted on 60 patients definitively diagnosed with primary knee osteoarthritis according to Modern medicine, and classified as “Hac tat phong” of the Wind-Cold-Damp Bi Syndrome type complicated by Kidney and Liver Deficiency according to Traditional medicine. Patients were purposively divided into two groups: Control group (n=30): Treated with TENS and Exercise therapy. Intervention group (n=30): Treated with Laser acupuncture, TENS, and Exercise therapy. The treatment course lasted 15 days. Results were compared both pre- and post-treatment, and against the control group. Results: The average age of the patients was 62.5±7.67 years, with a higher proportion of females (44/60) than males (16/60). Treatment results after 15 days showed that the combination of Laser acupuncture, TENS stimulation, and Exercise therapy significantly improved clinical outcomes: NRS pain scale score decreased by 3.73 points; Lequesne index decreased by 4.04 points; heel-to-buttock distance decreased by 8.57 cm; knee range of motion (ROM) increased by 300. No patient was recorded as having a poor treatment outcome. The differences between pre- and post-treatment and in comparison with the control group were statistically significant (p < 0.05). No adverse effects associated with the intervention were recorded during the entire treatment process. Conclusion: The combination of Laser acupuncture, TENS and Exercise therapy demonstrated a clearer analgesic effect and better improvement in range of motion compared to the control group, with p < 0.05. Adverse event monitoring: The method is safe, and no adverse effects were recorded throughout the study.
