Abstract

Electromyographic studies of the monosynaptic reflex in 70 Parkinsonian patients and 12 normal subjects show four types of abnormal facilitation and recovery curves in the Parkinsonian group, types that correspond to variations in the clinical syndrome; Cryosurgical lesions in the, ventro-lateral and ventro-postero-lateral nuclei of the thalamus restore essentially normal curves.
