Embodiment Construction

[0123] figure 1 A schematic overview of an exemplary embodiment of a system 10 for multi-channel and / or variable nerve stimulation with which the method according to the invention can be carried out is shown.

[0124] System 10 includes a controller 12 capable of controlling the components and modules specified below:

[0125] System 10 includes a finite time definition module 14 for defining finite time periods.

[0126] Still further, there is at least one pulse sequence setter 16 .

[0127] The pulse sequence setter 16 is configured and arranged to provide:

[0128] o at least a first pulse sequence provided on a first channel comprising a first frequency of stimulation events; and

[0129] o At least a second pulse sequence, the second pulse sequence is provided on a second channel comprising a second frequency of stimulation events.

[0130] In the sense of the present disclosure and the described example embodiments, a pulse sequence is to be understood as a finite t...

Abstract

The present invention relates to a method for providing multi-channel and / or variable neurostimulation comprising at least the following steps: defining a finite period of time; providing at least a first pulse train (PT1); providing at least a second pulse train (PT2); analyzing the first pulse train (PT1) and the second pulse train (PT2) for at least one potential overlap of stimulation events and / or using an analysis whether there is at least one potential overlap of stimulation events of the first pulse train and the second pulse train; in case of a detected overlap, adjusting the first pulse train (PT1) and / or the second pulse train (PT2) by Shifting the first pulse train (PT1) and the second pulse train (PT2) relatively to each other, so as to avoid at least partially the overlap ofstimulation events. Furthermore, the present invention relates to system (10) for multi-channel and / or variable neurostimulation.

Description

technical field [0001] The present disclosure relates to methods and systems for providing multi-channel variable neuromodulation. Background technique [0002] Epidural electrostimulation (EES) has shown promising results in the treatment of spinal cord injuries. The mechanism is unclear and still under investigation, but EES can both stimulate leg muscles through proprioceptive afferent fibers and restore neuronal networks in the spinal cord. EES uses a multielectrode array that is placed on top of the dura mater, just behind the spinal cord. In rats, the combination of a serotonergic agonist and EES rapidly shifts the spinal cord network from a non-functional to a highly functional and adaptive state as early as 1 week after injury (Courtine G et al., After Loss of Brain Input Conversion of non-functional spinal circuits to a functional state, Nature Neuroscience 12, 1333-1342, (2009)). In addition, EES restores voluntary control of movement by rewiring injured spinal ...
