Abstract

According to one embodiment, a system for neurological stimulation of peripheral nerve fibers to treat low back pain is provided. The system includes stimulation electrodes adapted to be implanted in tissue proximate a network of peripheral nerve fibers located in and innervating a painful region of the low back area and to deliver electrical stimulation pulses to the network of peripheral nerve fibers located in and innervating the painful region of the low back area. The system also includes a stimulation source adapted for implantation into the person'"'"'s body and operable to generate electrical stimulation pulses for transmission to the electrodes for delivery to the network of peripheral nerve fibers located in and innervating the painful region of the low back area to relieve pain in the painful region of the low back area.

Claims

1-21. -21. (canceled)

22. A method for treating low back pain, comprising:

identifying a region of low back pain in a patient;

identifying a sub-region having an approximate epicenter of pain within the region;

implanting one or more stimulation leads with a plurality of electrodes being disposed in the sub-region and substantially aligned along a greatest axis of the region of low back pain, wherein implanting comprises positioning the plurality of electrodes in the epidermis, dermis, or subcutaneous tissue superior to fascia containing a network of localized peripheral nerve fibers located in and influencing the painful region of the low back area without regard to a specific or identifiable nerve or nerve branch;

generating electrical pulses using an implantable pulse generator implanted in the patient, the implantable pulse generator being electrically coupled to the one or more stimulation leads; and

treating the patient'"'"'s low back pain by applying the generated electrical pulses from the implantable pulse generator to the plurality of electrodes to stimulate the network of localized peripheral nerve fibers located in and influencing the painful region of the low back pain.

23. The method of claim 22, wherein the implanting positions an electrode of the plurality of electrodes immediately proximate to an epicenter of pain.

24. The method of claim 22, wherein the stimulation source generates the stimulation pulses according to one or more stimulation sets each specifying a plurality of stimulation parameters to relieve pain in the painful region of the patient'"'"'s low back area.

25. The method of claim 24, wherein the stimulation parameters for a stimulation set comprising a polarity for each electrode at each of one or more times within a stimulation pulse for the stimulation set.

26. The method of claim 22, wherein the stimulation source generates the stimulation pulses according to a plurality of stimulation programs each comprising one or more stimulation sets, each stimulation set specifying a plurality of stimulation parameters to relieve pain in the painful region of the patient'"'"'s low back area.

27. The method of claim 22, wherein the electrical stimulation pulses of the network of localized peripheral nerve fibers provides paresthesia with respect to the painful region of the patient'"'"'s low back area.
