Methods for providing optimized neurostimulation

Abstract

Disclosed herein are methods for neurostimulation therapy for spinal cord injury. More particularly, the present invention relates to methods for neurostimulation therapy for spinal cord injury. More particularly, the present invention relates to methods for providing multiple independent, simultaneous waveforms in neurostimulation therapy while minimizing or substantially eliminating undesirable interactions between the waveforms.

What is claimed is: 
     
         1 . A method for providing optimized neurostimulation, comprising:
 providing an electrode array comprising a plurality of electrodes, wherein the plurality of electrodes are divided into at least two groups of electrodes, and wherein the electrode array is configured to generate at least two simultaneous waveforms;   providing a power source for each group of electrodes, each power source being electrically isolated and physically separate from each other power source; and   activating the electrode array to generate the at least two simultaneous waveforms.   
     
     
         2 . The method of  claim 1 , wherein, for each group of electrodes, each electrode within the group shares a common frequency and pulse width. 
     
     
         3 . The method of  claim 1 , wherein the electrode array is implanted in a patent. 
     
     
         4 . A method for providing optimized neurostimulation, comprising:
 providing an electrode array comprising a plurality of electrodes;   grouping the plurality of electrodes into a first group including at least one electrode configured to generate a first waveform, a second group including at least one electrode configured to generate a second waveform, and a third group including at least one electrode with a fixed potential, wherein the third group is located between the first group and the second group; and   activating the electrode array to generate at least one of the first waveform and the second waveform.   
     
     
         5 . The method of  claim 4 , wherein the electrode array is implanted in a patient. 
     
     
         6 . The method of  claim 4 , wherein the first group, the second group, and the third group each include at least two electrodes.
