Movement timing stimulator systems and methods that aid in the relief of the symptoms of neurological movement disorders are provided. In one embodiment, a method of improving a patient's gait is provided. The method includes producing a plurality of stimulation prompts at a plurality of stimulation points using multiple stimulation channels. The plurality of stimulation points is located symmetrically on each leg. The method further includes applying the plurality of stimulation prompts in a timed periodic fashion across the plurality of stimulation points and activating a return electrode whenever one of the multiple stimulation channels on an associated leg is active. The plurality of stimulation prompts are not synchronized with the patient's gait. Each of the multiple stimulation channels is associated with a stimulation electrode at one of the plurality of stimulation points.

L'invention concerne des systèmes et des procédés de stimulation de la synchronisation des mouvements contribuant au soulagement des symptômes de troubles dyskinétiques neurologiques. Un mode de réalisation concerne un procédé permettant d'améliorer la démarche d'un patient. Le procédé consiste à produire une pluralité de sollicitations de stimulation au niveau d'une pluralité de points de stimulation au moyen de plusieurs canaux de stimulation. La pluralité de points de stimulation est située de manière symétrique sur chaque jambe. Le procédé consiste également à appliquer la pluralité de sollicitations de stimulation de manière périodique temporisée dans la pluralité de points de stimulation et à activer une électrode de retour quand un des canaux de stimulation sur une jambe associée est actif. La pluralité de sollicitations de stimulation ne sont pas synchronisées avec la démarche du patient. Chaque canal de stimulation est associé à une électrode de stimulation au niveau d'un point de la pluralité de points de stimulation.
