RT Journal Article SR Electronic T1 Neurophysiological mechanisms in abnormal reflex activities in cerebral palsy and spinal spasticity. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 333 OP 342 DO 10.1136/jnnp.43.4.333 VO 43 IS 4 A1 G Barolat-Romana A1 R Davis YR 1980 UL http://jnnp.bmj.com/content/43/4/333.abstract AB 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.
