目的 定量分析神经科患者手臂震颤。方法 受测试者左 (右 )手拿光笔照射目标十字中心 ,用摄像机拍摄光点图像后数值化 ,对数据进行统计分析。结果 正常人组和病人组的手拿光笔照射目标十字中心时光点偏离目标十字中心的最大距离 (MR)、光点偏离目标十字中心的平均距离(AR) ,以及光点移动路径长度 (TL) ,均有显著性差异 (P <0 .0 5 )。结论 MR、AR、TL可作为神经科患者肢体震颤的定量判别指标。
Objective To measure arm's tremor of patients with neurological disease quantitatively. Methods Film images of light points which are irradiated to the center of cross, then the images are digitalized by computer. The maximum distance of light points departing the center of cross MR?the average distance of light points departing the center of cross AR and the total length of the track of light points TL are calculated. Results MR?AR?TL of patients with neurological disease are significantly different from those of normal people(P<0.05).Conclusion MR ?AR?TL can be referred as quantitative indexes of arm's tremor of patients with neurological disease.
