摘要
震颤临床评定量表(CRST)常用于在聚焦超声(FUS)丘脑切开术中评估本质性震颤(ET)。然而,它面临着天花板效应和测试-再测试变异性等挑战。本研究探讨了视频运动分析作为 ET 评估指标的实用性。43 名 ET 患者通过视频完成了姿势性震颤和画线任务,并使用运动分析软件对数据进行了分析。分析了测试-重复和评分者之间的可靠性、与 CRST 和震颤评分的相关性以及 FUS 治疗前后的比较。视频运动分析显示出极佳的测试-重复和评分者间可靠性。在姿势性震颤任务中,视频参数振幅与 CRST 和震颤评分显著相关。同样,在画线任务中,视频参数振幅与 CRST 和震颤评分有显著相关性,有效解决了天花板效应。关于 FUS 治疗后的改善情况,CRST 和震颤评分的变化与视频参数振幅的变化有显著相关性。总之,对 ET 的视频运动进行定量分析可精确评估运动学特征,并有效解决天花板效应和测试-再测试变异性问题。视频运动分析评分准确地反映了震颤的严重程度和治疗效果,显示了其较高的临床实用性。
Video Motion Analysis as a Quantitative Evaluation Tool for Essential Tremor during Magnetic Resonance-Guided Focused Ultrasound Thalamotomy.
The Clinical Rating Scale for Tremor (CRST) is commonly used to evaluate essential tremor (ET) during focused ultrasound (FUS) thalamotomy. However, it faces challenges such as the ceiling effect and test-retest variability. This study explored the utility of videographic motion analysis as an evaluation index for ET. Forty-three patients with ET performed postural tremor and line-drawing tasks recorded on video, and the data were analyzed using motion analysis software. The test-retest and inter-rater reliability, correlations with the CRST and tremor scores, and pre/post-FUS treatment comparisons were analyzed. The video motion analysis showed excellent test-retest and inter-rater reliability. In the postural tremor tasks, video parameter amplitude significantly correlated with the CRST and tremor scores. Similarly, for the line-drawing task, video parameter amplitude showed significant correlations with CRST and tremor scores, effectively addressing the ceiling effect. Regarding post-FUS treatment improvements, changes in the CRST and tremor scores were significantly associated with changes in video parameter amplitude. In conclusion, quantitative analysis of the video motion of ET enables precise evaluation of kinematic characteristics and effectively resolves the ceiling effect and test-retest variability. The video motion analysis score accurately reflected the tremor severity and treatment effects, demonstrating its high clinical utility.
