dback risulta di fondamentale importanza nel migliorare la qualità
del controllo e nell’incorporazione della protesi stessa nello schema
corporeo del suo utilizzatore. L’esercizio nel controllo della
mano robotica e nella percezione sensoriale ha prodotto una normalizzazione
delle mappe in corteccia motoria che prima dell’impianto
presentavano una abnorme e asimmetrica ipereccitabilità
nell’emisfero cui compete il moncherino e un miglioramento
della sindrome da arto fantasma, con un progressivo ritorno ad
una percezione più fisiologica del fantasma dell’arto perso. Questi
miglioramenti sono spariti a 3 mesi di follow-up dall’espianto
degli elettrodi. In linea con recenti affermazioni sull’applicazione
di interfacce neurali in neuro riabilitazione 9 28 29 questo lavoro
dimostra che un sistema protesico con interfaccia neurale caratterizzato
da una elevata interattività col suo utilizzatore può essere
considerato uno strumento neuroriabilitativo, perché in grado di
indurre una riduzione della neuro plasticità aberrante e dei suoi
effetti negativi.
