Systems and external programmers provide therapy to a patient having a dysfunction. In one aspect, electrical energy is conveyed between electrodes to create a stimulation region in tissue adjacent the electrodes. Physiological information from the patient is acquired and analyzed, and a locus of the stimulation region is electronically displaced relative to the tissue based on the analysis of the acquired physiological information. In another aspect, electrical energy is delivered to tissue of the patient in accordance with one or more stimulation parameters. A cognitive brain signals is sensed and analyzed, and the stimulation parameter(s) are modified based on the analysis of the cognitive brain signal.

L'invention concerne des systèmes et des programmateurs externes qui fournissent une thérapie à un patient souffrant d'un dysfonctionnement. Selon un aspect, de l'énergie électrique est transmise entre des électrodes pour créer une zone de stimulation dans un tissu adjacent aux électrodes. Des informations physiologiques provenant du patient sont acquises et analysées, et un locus de la zone de stimulation est déplacé de manière électronique par rapport au tissu sur la base de l'analyse des informations physiologiques acquises. Selon un autre aspect, de l'énergie électrique est délivrée à un tissu du patient selon un ou plusieurs paramètres de stimulation. Des signaux cérébraux cognitifs sont détectés et analysés, et le ou les paramètres de stimulation sont modifiés sur la base de l'analyse du signal cérébral cognitif.
