Hand tremor often causes disability in patients with essential tremor (ET). Aim of the study was to investigate whether tremor magnitude, a new single quantitative score obtained from digital tablet recordings of writing and drawing, is able to adequately reflect disability in ET patients. Mean tremor magnitude values showed significant difference between 14 ET patients and 14 healthy age matched controls (p<0.0001). The tremor magnitude values showed significant correlation with standard methods of clinical assessment (p<0.01). We present tremor magnitude as an index that reflects disability resulting from tremor and can help to evaluate ET.
手部震颤常导致特发性震颤（ET）患者出现功能障碍。本研究的目的是调查震颤幅度，一种从书写和绘图的数字平板记录中获得的新的单一量化评分，是否能够充分反映ET患者的功能障碍。14例ET患者和14例年龄匹配的健康对照者之间的平均震颤幅度值存在显著差异（p<0.0001）。震颤幅度值与临床评估的标准方法显著相关（p<0.01）。我们提出震颤幅度作为反映震颤所致功能障碍的指标，有助于评估ET。
