SYSTEMS AND METHODS FOR TREATING MOVEMENT DISORDERS
First Claim
1. A method of relieving a patient'"'"'s symptoms of a movement disorder, the method comprising:
- determining the timing and phase of a plurality of stimulation prompts;
calculating the amplitude of the plurality of stimulation prompts such that the plurality of stimulation prompts do not force muscle contraction in the patient; and
producing the plurality of stimulation prompts at a plurality of stimulation points located on the patient'"'"'s body, based on the determined timing, phase and calculated amplitude to facilitate muscle contraction controlled by the patient'"'"'s central nervous system in response to the plurality of stimulation prompts.

Abstract
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.

11. A movement timing stimulator system for the treatment of a patient'"'"'s symptoms of a movement disorder, the system comprising:
-
a controller configured to control the timing and amplitude of a plurality of stimulation prompts such that the stimulation prompts do not force muscle contraction in the patient and facilitate muscle contraction controlled by the patient'"'"'s central nervous system; and a plurality of stimulators configured to be located at a plurality of stimulation points on the patient'"'"'s body and to produce the plurality of stimulation prompts based on control signals from the controller. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
