Abstract
The present invention reduces pain and improves function long-term in persons with back pain using electrical stimulation in the back. This approach involves an electrical stimulation device including at least one electrode adapted for insertion within an animal body with back pain and at least one pulse generator operatively coupled with the at least one electrode, wherein the pulse generator delivers electrical stimulation activating at least a nerve innervating at least a paraspinal muscle in a back of the animal body for pain relief.
Claims31
A method comprising
- percutaneously inserting a spiral or helically coiled lead having at least one electrode within tissue;
- and
- applying an intensity of electrical stimulation via an electrical stimulation device via the at least one electrode to at least one peripheral nerve of the tissue;
- and
- activating central pain processing via generation of afferent signals without requiring stabilization of a spine, musculature or connective tissue.
A method comprising
- percutaneously inserting a spiral or helically coiled lead having at least one electrode within tissue;
- and
- applying an intensity of electrical stimulation via an electrical stimulation device via the at least one electrode to at least one peripheral nerve of the tissue;
- modulating central pain processing via the electrical stimulation of the at least one peripheral nerve;
- and
- activating paraspinal muscles without strengthening of the paraspinal muscles.
A method comprising
- percutaneously inserting a spiral or helically coiled lead having at least one electrode within muscle;
- and
- applying an intensity of electrical stimulation via an electrical stimulation device via the at least one electrode to at least one peripheral nerve of the muscle;
- stimulating nerve fiber in the at least one peripheral nerve;
- and
- producing changes in central pain processing to modulate a perception of pain, without requiring changes to be manifested in the muscle.
A method comprising
- percutaneously inserting a spiral or helically coiled lead having at least one electrode within at least one muscle in a back of a body;
- and
- applying an intensity of electrical stimulation via an electrical stimulation device via the at least one electrode to at least one peripheral nerve of the at least one muscle;
- activating motor axons of the at least one muscle;
- and
- causing muscle contraction of the at least one muscle without activation of painful sensory axons relieving back pain of the body.
A method comprising
- percutaneously inserting a spiral or helically coiled lead having at least one electrode within a tissue;
- and
- applying an intensity of electrical stimulation via an electrical stimulation device via the at least one electrode to peripheral nerve fibers of the tissue;
- activating modulation of central pain processing through the electrical stimulation of peripheral nerve fibers;
- producing afferent neural signals;
- and
- altering central neural nociceptive processing preventing pain sensation.
