 In 1967 Claude Gros and his colleagues at the neurosurgical hospital (CHU Gui de Chauliac) in Montpellier resurrected posterior rhizotomy for spasticity.Fasano of Italy in 1978 introduced 'selective' posterior rootlet rhizotomy for cerebral palsy patients and Warwick Peacock developed the Gros technique at the Red Cross War Memorial Children's Hospital in Cape Town, South Africa, by exposing the cauda equina, rather than at the spinal cord level.Peacock moved to Los Angeles in 1986 and began campaigning rather widely for SDR's viability in cerebral palsy spasticity relief.
