A method for measuring head tremor and rotation in spasmodic torticollis using specially devised instrument is described in detail. Repeated measurements in ten patients with spasmodic torticollis have revealed this method to be consistently reproducible regarding both the rotation and tremor of the head. Analysis of the tremor recordings from these patients reveals basically two types of head tremor, (a) a regular tremor varying in rate from 4 to 7 cycles per second and (b) an irregular tremor which varies in frequency as well as amplitude at different times of recording. This method provides quantitative data regarding the two outstanding features of spasmodic torticollis, viz: head rotation and head tremor, and is especially suited for comparing clinical response to various forms of treatment as well as studying the natural history of this disease.
本文详细描述了一种使用专门设计的仪器测量痉挛性斜颈患者头部震颤和旋转的方法。对10例痉挛性斜颈患者进行的重复测量表明，该方法在头部旋转和震颤方面均具有一致的可重复性。对这些患者震颤记录的分析显示，头部震颤基本上有两种类型：(a) 频率为每秒4至7次的规则震颤；(b) 不规则震颤，其频率和幅度在不同记录时间有所变化。该方法提供了有关痉挛性斜颈两个突出特征的数据，即头部旋转和头部震颤，特别适用于比较各种治疗形式的临床反应以及研究该疾病的自然史。
