Performance on two sensorimotor tasks was compared between 28 patients with Parkinsonism and 28 age and sex matched controls. One task involved complex motor activity (the Bead and Tapper test) and the other simple motor activity with a verbal component (the Letter Cancellation test). Both tests had three levels of complexity. Under conditions of increasing complexity in the performance required, the scores for the Parkinsonism subjects decreased disproportionately compared with the controls. This finding was more clearly established for the Bead and Tapper test than for the Letter Cancellation test. These results confirmed previous studies, and the nature of a possible central programming deficit was discussed. Laterality of brain involvement in the Parkinsonism subjects had no significant effect.
对28名帕金森病患者和28名年龄及性别相匹配的对照者在两项感觉运动任务中的表现进行了比较。一项任务涉及复杂的运动活动（珠子敲击测试），另一项是带有语言成分的简单运动活动（字母划消测试）。两项测试都有三个复杂程度级别。在所需表现的复杂程度增加的情况下，帕金森病受试者的得分与对照组相比下降幅度不成比例。这一发现对于珠子敲击测试比字母划消测试更为明显。这些结果证实了先前的研究，并对可能的中枢编程缺陷的性质进行了讨论。帕金森病受试者大脑受累的侧别没有显著影响。
