title: Neurophysiological mechanisms in abnormal reflex activities in cerebral palsy and spinal spasticity.
abstract: Dorsal root stimulation, carried out during operation in 80 spastic cerebral palsy patients and in one spastic quadriplegic patient, allowed a study of abnormal monosynaptic and polysynaptic reflexes. Frequency-related depression of the monosynaptic reflex was not present; increased activity through non-suppressed polysynaptic pathways was shown.
