The influence of vibratory stimuli upon the spinal motoneurone pool was investigated using H-reflex recorded from the gastrocnemius muscle. The H_1 and H_2 were measured, and augmentation and reduction ratios were made in this study upon the patient with spasticity, rigidity, flaccid palsy and cerebellar disturbance. These ratios were plotted in the graph, which reflects of spreading and/or narrowing of discharge zone and some parts of subliminal fringe which were influenced by vibratory stimli given to the extremities of the patients with muscle tone abnormality. In spaticity, a certain abnormal spreading of discharge zone was recognized when vibratory stimulation was given to the upper extremities. In rigidity, some obvious suppressions were seen when the vibratory stimulation was given to the gastrocnemius muscle, and abnormal facilitation could be observed when vibratory stimulation was given to the contralateral upper extremity when the gastrocnemius was vibrated at the same time. This method is considered as a meaningful examination to evaluate the excitability in the spinal motoneurone pool in various muscle tone abnormalities.
