Systems and methods for treating shoulder pain related to subacromial impingement syndrome
View Patent ↗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.
1. A method comprising the steps of:
percutaneously inserting a lead into a patient;
placing an electrode in subepidermal tissue of the patient, the electrode operatively coupled with the lead; and
delivering electrical stimulation through the electrode producing a muscle contraction in a target area and altering maladaptive neuroplasticity in a central nervous system of the patient producing a therapeutic effect.
2. The method of claim 1 wherein during the delivering step, a level of pain perceived by the patient, whereby the pain was caused by or occurring secondarily to subacromial impingement syndrome, is reduced.
3. The method of claim 1 , wherein the patient is a human.
4. The method of claim 1 , wherein the lead is attached with the electrode.
5. The method of claim 1 , wherein the electrode is formed as part of the lead.
6. The method of claim 1 , wherein the electrode is carried on the lead.
7. The method of claim 1 , wherein the electrode extends from a conductor attached with the lead.
8. The method of claim 1 , 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.
9. A method comprising the steps of:
percutaneously inserting a lead into a patient;
placing an electrode in subepidermal tissue of the patient, the electrode operatively coupled with the lead; and
delivering electrical stimulation through the electrode to generate a muscle contraction in a target area and reduce central hypersensitivity in the patient producing a therapeutic effect.
10. The method of claim 9 , wherein parameters of the electrical stimulation comprise 12 Hz, 20 mA and a pulse duration of 60 μs.
11. The method of claim 1 , wherein the therapeutic effect is a reduction in pain.
12. The method of claim 9 , wherein the electrode is spaced an electrically effective distance from a neurological motor point.
13. The method of claim 9 , wherein the reduction central hypersensitivity in the patient reduces chronic pain in the patient.
14. The method of claim 13 , wherein the pain is caused by or secondarily to subacromial impingement syndrome.
15. The method of claim 9 , wherein the electrode is spaced an electrically effective distance from a neurological motor point.
16. The method of claim 9 , wherein the therapeutic effect is a reduction in pain.
17. A method comprising the steps of:
percutaneously inserting a lead into a patient;
placing an electrode in subepidermal tissue of the patient, the electrode operatively coupled with the lead; and
delivering electrical stimulation through the electrode to generate a muscle contraction in a target area and sustain functional reorganization of maladaptive neuroplastic changes of a nervous system of the patient associated with chronic pain.
18. The method of claim 17 , wherein the electrode is spaced an electrically effective distance from a neurological motor point.
19. The method of claim 17 , wherein parameters of the electrical stimulation comprise 12 Hz, 20 mA and a pulse duration of 60 μs.
20. A method comprising the steps of:
percutaneously inserting a lead into a tissue of a human; and
delivering stimulation through at least one electrode operatively coupled with the lead to a neurological motor point of the human generating a muscle contraction in a target area changing central nervous system maladaptive neuroplasticity of the human producing a therapeutic effect.
21. The method of claim 20 , wherein the electrode is spaced an electrically effective distance from the neurological motor point.
22. The method of claim 20 , wherein parameters of the stimulation comprise 12 Hz, 20 mA and a pulse duration of 60 μs.
23. The method of claim 20 , wherein the at least one electrode consists of a single electrode.
24. The method of claim 20 , wherein the delivering step relieves chronic pain.
25. The method of claim 20 , wherein parameters of the electrical stimulation comprise 12 Hz, 20 mA and a pulse duration of 60 μs.
26. The method of claim 20 , wherein the therapeutic effect is a reduction in pain.
