SPINAL CORD STIMULATION WITH INTERFERENTIAL CURRENT USING MULTIPLE BEAT SIGNALS

摘要

An example method for spinal cord stimulation treatment includes positioning eight implantable electrodes to a dura matter in an epidural space proximate to a subject's spinal cord so that (i) a first circuit is created between a first and second electrode on a first channel, (ii) a second circuit is created between a third and fourth electrode on a second channel, (iii) a third circuit is created between a fifth and sixth electrode on a third channel, and (iv) a fourth circuit is created between a seventh and eighth electrode on a fourth channel, transmitting signals through the first and second circuits that interfere to produce a first beat signal, transmitting signals through the third and fourth circuits that interfere to produce a second beat signal, and interaction of the first and second beat signals results in a combined beat signal proximate to and / or within the subject's spinal cord.
