The aim of the present study was to investigate and compare the effects of high intensity laser therapy (HILT) and low level laser therapy (LLLT) on the treatment of patients with Bell's palsy. Forty-eight patients participated in and completed this study. The mean age was 43 ± 9.8 years. They were randomly assigned into three groups: HILT group, LLLT group, and exercise group. All patients were treated with facial massage and exercises, but the HILT and LLLT groups received the respective laser therapy. The grade of facial recovery was assessed by the facial disability scale (FDI) and the House-Brackmann scale (HBS). Evaluation was carried out 3 and 6 weeks after treatment for all patients. Laser treatments included eight points on the affected side of the face three times a week for 6 successive weeks. FDI and HBS were used to assess the grade of recovery. The scores of both FDI and HBS were taken before as well as 3 and 6 weeks after treatment. The Friedman test and Wilcoxon signed ranks test were used to compare the FDI and HBS scores within each group. The result showed that both HILT and LLLT significantly improved the recovery of patients with Bell's palsy. Moreover, HILT was the most effective treatment modality compared to LLLT and massage with exercises. Thus, both HILT and LLLT are effective physical therapy modalities for the recovery of patients with Bell's palsy, with HILT showing a slightly greater improvement than LLLT.
本研究的目的是调查和比较高强度激光疗法（HILT）和低强度激光疗法（LLLT）对贝尔面瘫患者的治疗效果。48名患者参与并完成了本研究。平均年龄为43±9.8岁。他们被随机分为三组：HILT组、LLLT组和运动组。所有患者均接受面部按摩和运动治疗，但HILT组和LLLT组接受各自的激光治疗。通过面部残疾量表（FDI）和House-Brackmann量表（HBS）对面部恢复程度进行评估。所有患者在治疗后3周和6周进行评估。激光治疗包括在患侧面部的8个点，每周3次，连续6周。使用FDI和HBS评估恢复程度。在治疗前以及治疗后3周和6周记录FDI和HBS的分数。使用Friedman检验和Wilcoxon符号秩检验比较每组内的FDI和HBS分数。结果表明，HILT和LLLT均显著改善了贝尔面瘫患者的恢复情况。此外，与LLLT和运动按摩相比，HILT是最有效的治疗方式。因此，HILT和LLLT都是贝尔面瘫患者恢复的有效物理治疗方式，HILT的改善效果略优于LLLT。
