Abstract

A control system for use with a neurostimulator comprises a user interface for receiving an input from a user and a controller. The user interface has a first control and a second control. The controller is configured for, in response to actuating the first control, operating the neurostimulation control system in a PNFS programming mode, and for, in response to actuating the second control, operating the neurostimulation control system in a PNS programming mode. A method of providing therapy to a patient comprises initially conveying pulsed electrical current at a pulse width into a peripheral tissue region of the patient to create a side effect via stimulation of one of a nerve ending and neural axon, and subsequently conveying pulsed electrical current at an adjusted pulse width into the peripheral tissue region to create a therapeutic effect via stimulation of the other one of the nerve ending and neural axon.

First claim

What is claimed is:

1. A method of providing therapy to a patient, comprising:
initially conveying cathodic pulsed electrical current at a pulse amplitude and a pulse width into a peripheral tissue region of the patient to initially stimulate
a nerve ending to create a side effect local to the peripheral neural tissue region;

increasing the pulse width; and
subsequently conveying cathodic pulsed electrical current at the increased pulse width into the peripheral tissue region of the patient to only stimulate
the neural axon to create a therapeutic effect remote from the peripheral neural tissue region.

2. The method of claim 1 , wherein the both the initially and subsequently conveyed pulsed electrical current have the same pulse amplitude.

3. The method of claim 1 , wherein the pulse width is increased to a value greater than 500 μs.

4. The method of claim 1 , wherein the therapeutic effect is a reduction in or elimination of pain.

5. The method of claim 1 , further comprising adjusting the pulse amplitude, wherein the pulsed electrical current is subsequently conveyed at the adjusted pulse amplitude into the peripheral region of the patient.

6. A method of providing therapy to a patient, comprising:
delivering cathodic pulsed electrical current into a peripheral tissue region, including creating a side effect by delivering the pulsed electrical current with a first pulse width, and then only creating a therapeutic effect by delivering cathodic pulse electrical current at a second pulse width that is greater than the first pulse width,
wherein creating the side effect and then only creating the therapeutic effect includes
creating the side effect local to the peripheral region and creating the therapeutic effect remote from the peripheral region.

7. The method of claim 6 , wherein creating the side effect includes stimulating a nerve ending in the peripheral tissue region, and creating the therapeutic effect includes stimulating a neural axon in the peripheral neural tissue region.

8. The method of claim 7 , wherein the second pulse width is greater than 500 μs.

9. A method of providing therapy to a patient, comprising:
creating a side effect, including delivering cathodic pulsed electrical current with a first pulse width into a peripheral tissue region, wherein creating the side effect includes
creating the side effect local to a peripheral neural tissue region, including delivering the pulsed electrical current to a nerve ending in the peripheral tissue region;
and

only creating a therapeutic effect subsequent to creating the side effect, including delivering cathodic pulsed electrical current with a second pulse width into the peripheral tissue region, the second pulse width being greater than the first pulse width, wherein creating the therapeutic effect includes
creating the therapeutic effect remote from the peripheral tissue region, including delivering the cathodic pulsed electrical current with the second pulse width to the neural axon in the peripheral tissue region.
