Abstract

Systems and methods are provided for treating chronic pain occurring secondarily to subacromial impingement syndrome in a human body. A system is provided to deliver percutaneous electrical stimulation through at least one electrode to neurological motor points of the posterior and middle deltoid muscles to mediate such pain. One-time, continued and/or periodic dosing of treatment methods according to the present invention may result in a change to central nervous system maladaptive neuroplasticity.

Claims

1. A method comprising the steps of:

placing an electrode in subepidermal tissue of a human; and

delivering electrical stimulation through the electrode,

wherein, after the delivering step, a level of pain perceived by the human, wherein the pain was caused by or occurring secondarily to subacromial impingement syndrome, is reduced.

2. A method according to claim 1, wherein during the delivering step, a level of pain perceived by the human, wherein the pain was caused by or occurring secondarily to subacromial impingement syndrome, is reduced.

3. A method comprising the steps of:

percutaneously inserting or instructing percutaneous insertion of a lead into a patient, the lead having an electrode wherein the electrode is positionable in subepidermal tissue of the patient;

delivering or instructing delivery of electrical stimulation through the electrode altering maladaptive neuroplasticity in a central nervous system of the patient; and

reducing or eliminating chronic pain of the patient.

4. The method of claim 3, wherein the lead is attached with the electrode.

5. The method of claim 3, wherein the electrode is formed as part of the lead.

6. The method of claim 3, wherein the lead includes a portion having an insulated body and the electrode is formed from a portion of the lead free of the insulated body.

7. The method of claim 3 further comprising producing or instructing production of a muscle contraction in a target area.

8. A method comprising the steps of:

percutaneously inserting or instructing percutaneous insertion of a lead into a patient;

placing or instructing placement of an electrode in subepidermal tissue of the patient, the electrode operatively coupled with the lead;

delivering or instructing delivery of electrical stimulation through the electrode to generate a muscle contraction in a target area;

reducing or instructing reduction of central hypersensitivity in the patient; and

producing or instructing production of a therapeutic effect of reducing chronic pain in the patient.

9. A method comprising the steps of:

percutaneously inserting or instructing percutaneous insertion of a lead into a patient;

placing or instructing placement of an electrode in subepidermal tissue of the patient, the electrode operatively coupled with the lead;

delivering or instructing delivery of electrical stimulation through the electrode to generate a muscle contraction in a target area; and

sustaining or instructing sustaining of functional reorganization of maladaptive neuroplastic changes of a nervous system of the patient associated with chronic pain.

10. A method comprising the steps of:

percutaneously inserting or instructing percutaneous insertion of a lead into a tissue of a human; and

delivering or instructing delivery of stimulation through at least one electrode operatively coupled with the lead to a neurological motor point of the human;

generating or instructing generation of a muscle contraction in a target area; and

changing or instructing change of central nervous system maladaptive neuroplasticity of the human producing a therapeutic effect to reduce chronic pain.
