A method for the continuous registration of rapid isometric force changes was investigated in 24 healthy control persons, 10 hemiparetic patients and 10 cerebellar patients. Though the selection of both patient groups involved comparable deficits with respect to the number of force changes attained, the analysis of the underlying force-velocity patterns revealed considerable differences in the performance of hemiparetic and cerebellar patients. Hemiparetic patients showed gross deficits in both the force increasing and decreasing phases. In contrast to this, most cerebellar patients were able to release force as fast as normal controls, while marked slowness was only found for the force increasing phases.
在24名健康对照者、10名偏瘫患者和10名小脑病变患者中研究了一种连续记录快速等长力变化的方法。尽管两组患者在达到的力变化数量方面存在类似的缺陷，但对潜在力-速度模式的分析显示，偏瘫患者和小脑病变患者的表现存在显著差异。偏瘫患者在力增加和减少阶段均表现出明显缺陷。与此相反，大多数小脑病变患者能够像正常对照者一样快速释放力，而仅在力增加阶段发现明显迟缓。
