The purpose of this study was to compare the scores of two clinical rating scales and high-speed video system measurements obtained during spontaneous eyelid movements in hemifacial spasm (HFS) patients before and after treatment. Patients were evaluated before and 30 days after receiving treatment with onabotulinumtoxinA injections. Using a high-speed video system, the eyelid movements were recorded bilaterally for 3 min and the energy power generated by the upper eyelid during spontaneous eyelid movements was assessed before and after treatment. The scores of the Jankovic rating scale (JRS) and Hemifacial Spasm Grading System (HSGS) were also assessed before and after treatment. The authors studied 22 patients. Significant reduction in JRS and HSGS scores and in the energy generated by the upper eyelid was observed after treatment. A power spectrum of less than 23,000 was associated with JRS and HSGS scores less than 4 and 6.25, respectively and a power spectrum greater than or equal to 23,000 was associated with JRS and HSGS scores greater than or equal to 4 and 6.25, respectively (p < 0.0001 and p = 0.0025). Rating systems are easy to use, but they may exhibit limitations in sensitivity to assess differences between distinct disease patterns and between subtle differences in treatment responses. The high-speed video system permits a greater degree of accuracy, which allows for the assessment of differences in eyelid movement patterns and would permit better tailoring of treatment to patients. However, simpler devices employing this system would need to be developed, so that it could be used in clinical practice.

本研究的目的是比较在治疗前后面肌痉挛 (HFS) 患者自发性眼睑运动过程中获得的两种临床评分量表和高速视频系统测量值的分数。在接受肉毒杆菌毒素 A 注射治疗前和治疗后 30 天对患者进行评估。使用高速视频系统，双侧记录眼睑运动 3 分钟，并在治疗前后评估自发性眼睑运动过程中上眼睑产生的能量。在治疗前后还评估了 Jankovic 评分量表 (JRS) 和面肌痉挛分级系统 (HSGS) 的分数。作者研究了 22 名患者。治疗后观察到 JRS 和 HSGS 评分以及上眼睑产生的能量显着降低。p  < 0.0001 和p  = 0.0025)。评级系统易于使用，但它们在评估不同疾病模式之间的差异和治疗反应的细微差异之间的敏感性方面可能存在局限性。高速视频系统具有更高的准确性，可以评估眼睑运动模式的差异，并可以更好地为患者量身定制治疗方案。然而，需要开发使用该系统的更简单的设备，以便它可以用于临床实践。
