[9 years of electric stimulation in Abruzzo. cognitive findings]

Data relating to 9 years of definitive electrostimulation in the Abruzzo region are presented. An account is given of the epidemiology, the indications for implantation, the stimulation and control technology, and the complications. It is pointed out that the implantability index rose from 1976 to 1978 to reach values of 130.5 implants/mil/inhab. This is in comparable with that in the literature. The technologies and modalities are rapidly developing, and a definitive picture cannot be drawn as yet. Further cognitive investigations are envisaged.
