The effects of chronic anterior lobe cerebellar stimulation on patients with cerebral palsy have been investigated using a new method of quanitfying muscle rigidity and stretch reflexes. The ankle is oscillated sinusoidally, compliance is measured at several frequencies, and electromyographic activity of the extensor and flexor muscles is recorded. In some patients stimulation can reduce rigidity and coactivation of muscles immediately or slowly over days or months. In others no change is found.
采用一种量化肌肉僵硬和牵张反射的新方法，对慢性小脑前叶刺激治疗脑瘫患者的效果进行了研究。使踝关节做正弦摆动，在几个频率下测量顺应性，并记录伸肌和屈肌的肌电活动。在一些患者中，刺激可立即或在数天或数月内缓慢降低肌肉的僵硬程度及共同激活。而在另一些患者中则未发现变化。
