The pathological stereotypies frequently observed among severely mentally retarded and autistic persons are highly rhythmical in nature. Most attempts to quantify such behavior, however, have not analyzed stereotypy in terms of its cyclical properties. In the present paper we have detailed a method for electronically transducing stereotyped body-rocking and analyzing its frequency and amplitude characteristics with a standard polygraph and microprocessor. The relationship between stereotyped body-rocking and cardiac activity was also described using time-series analysis. The method described should provide a sensitive index of various experimental manipulations and treatment effects.
在重度智力迟钝和自闭症患者中经常观察到的病理性刻板行为本质上具有高度的节律性。然而，大多数量化此类行为的尝试并未从其周期性特性方面分析刻板行为。在本文中，我们详细介绍了一种通过电子方式转换刻板的身体摇摆，并使用标准测谎仪和微处理器分析其频率和幅度特征的方法。还使用时间序列分析描述了刻板身体摇摆与心脏活动之间的关系。所描述的方法应该能为各种实验操作和治疗效果提供一个敏感的指标。
