The validity and reproducibility of two simple coordination-tests, the spiraltest and nailtest were examined in 113 healthy subjects, 33 patients with Parkinson's disease and 24 patients suffering from cerebellar disorders. The performances of the healthy subjects decreased significantly with age but gender had no influence. The performances of the dominant hands were significantly better. At a specificity of 90% the sensitivity was about 70% for the nailtest and about 75% for the spiraltest. For the patients with Parkinson's disease the spiraltest was more accurate than the nailtest. Since reference values are available these tests can be useful in the diagnostic process if a patient is suspected of a coordination disorder of the hands. Furthermore they are likely to give a better impression of the course of a disease affecting the coordination than if only clinical judgment is used.
在113名健康受试者、33名帕金森病患者和24名患有小脑疾病的患者中，对两种简单的协调测试——螺旋测试和指甲测试的有效性和可重复性进行了检查。健康受试者的测试表现随年龄显著下降，但性别没有影响。优势手的表现明显更好。在特异性为90%时，指甲测试的敏感性约为70%，螺旋测试的敏感性约为75%。对于帕金森病患者，螺旋测试比指甲测试更准确。由于有参考值，如果怀疑患者存在手部协调障碍，这些测试在诊断过程中可能会有用。此外，与仅使用临床判断相比，它们可能会更清楚地显示影响协调性的疾病进程。
