A compensatory tracking experiment was performed to investigate, on the basis of control theory, the dynamic characteristics of control movement in patients with progressive muscular dystrophy (limb-girdle type) and with myotonic dystrophy. Error scores and operator's transfer functions were estimated from the tracking data. The latter were approximated by a model which was composed of a gain constant, a delayed time constant and a dead time. The results showed that error scores for the muscular dystrophy patients and for the myotonic dystrophy patients were, in this order, greater than those for the normal subjects; the dynamic characteristics described by the transfer functions of the three groups were different from each other in terms of gain, phase lag and linearity of their operation. These results were discussed in terms of the stage of disability of motor function and the deterioration of intelligence with disease.
进行了一项补偿跟踪实验，以基于控制理论研究进行性肌营养不良（肢带型）和强直性肌营养不良患者控制运动的动态特性。从跟踪数据中估计误差分数和操作者的传递函数。后者由一个由增益常数、延迟时间常数和死区时间组成的模型近似。结果表明，肌营养不良患者和强直性肌营养不良患者的误差分数依次大于正常受试者；三组传递函数所描述的动态特性在增益、相位滞后和操作线性方面彼此不同。根据运动功能的残疾阶段和疾病导致的智力衰退对这些结果进行了讨论。
