An investigation has been carried out in a group of 84 (+2) patients suffering from myotonic dystrophia (Curschmann-Steinert). Manual measurements show that in these patients: (1) the alpha rhythms have low frequencies, related to the age of the patient and to the duration and severity of the disease; (2) the alpha rhythms are regular, monotonous; (3) the alpha rhythms have small amplitudes; there appears to be no relation between alpha frequency and amplitude; (4) the alpha indices are high during eyes closed as well as during eyes open. The computer measurements generally appear to concur with the above and in addition show that the bilateral and longitudinal coherences are high, indicating considerable synchrony of the alpha rhythm over large areas on both sides of the head. The possible significance of these observations is discussed.
对一组84（±2）例肌强直性营养不良（库尔施曼 - 施泰纳特病）患者进行了一项调查。手动测量结果显示，在这些患者中：（1）α节律频率较低，与患者年龄、疾病持续时间和严重程度有关；（2）α节律规则、单调；（3）α节律振幅较小；α频率与振幅之间似乎没有关系；（4）闭眼和睁眼时α指数均较高。计算机测量结果总体上似乎与上述情况一致，此外还显示双侧和纵向相干性较高，表明头部两侧大面积区域的α节律存在相当程度的同步性。讨论了这些观察结果可能具有的意义。
