Title
(EN) TREATMENT OF GAIT IMPAIRMENT USING DEEP BRAIN STIMULATION
(FR) TRAITEMENT D'UN TROUBLE DE LA MARCHE À L'AIDE D'UNE STIMULATION CÉRÉBRALE PROFONDE
Abstract
(EN) There is provided a stimulation device for treatment of gait impairment of a patient. The stimulation device is configured to apply respective stimulation signals to electrodes bilaterally implanted in two subcortical regions of the left and right hemispheres of the brain of the patient, the subcortical regions being associated with motor control. The stimulation device is configured to apply respective stimulation signals having a rate of electrical energy delivered that is modulated with alternating waveforms at a gait frequency and out of phase with each other.
(FR) L'invention concerne un dispositif de stimulation pour le traitement d'un trouble de la marche d'un patient. Le dispositif de stimulation est conçu pour appliquer des signaux de stimulation respectifs à des électrodes implantées bilatéralement dans deux régions sous-corticales des hémisphères gauche et droit du cerveau du patient, les régions sous-corticales étant associées à une commande motrice. Le dispositif de stimulation est conçu pour appliquer des signaux de stimulation respectifs ayant un taux d'énergie électrique fournie qui est modulé avec des formes d'onde alternatives à une fréquence de marche et déphasées l'une par rapport à l'autre.
