我们对10例OPCA患者、10例其他SCD患者和5例疑似OPCA患者进行了手指敲击测试，要求受试者对周期性声音信号做出同步反应。结果表明，OPCA患者对SCD的反应具有特异性。响应与高于2.5 Hz的信号并不同步，并且出现了两种响应类型的随机混合，频率低于信号和高于信号。这些延迟反应和加速反应分别代表了除OPCA和帕金森病之外的SCD患者的特征性反应特征。两种类型的反应与小脑病变和黑质纹状体病变有关。因此，手指敲击测试提供了区分OPCA和SCD的有效手段。
A finger tapping test in which the subject was requested to respond synchronously to the periodic sound signal was performed on 10 patients with OPCA, 10 other SCD and five suspected OPCA. The results indicated that the response of the patients with OPCA was specific among SCD. The response did not more synchronize to the signal above 2.5 Hz and a random mixture of two types of the response appeared with frequencies lower and higher than the signal. These delayed and hastened responses represented the characteristic response feature for the patients with SCD except OPCA and those with Parkinson's disease, respectively. Two types of the response were related to cerebellar lesions and to nigrostriatal lesions. The finger tapping test thus offers a useful means to differentiate OPCA among SCD.
