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:

inserting a lead percutaneously into a human;

placing an electrode in subepidermal tissue of the human, the electrode operatively coupled with the lead; 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 a lead into a tissue of a human;

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

mediating pain caused by or occurring secondarily to subacromial impingement syndrome.

4. The method of claim 3, wherein the neurological motor point includes a neurological motor point of posterior and middle deltoid muscles.

5. The method of claim 3, further comprising the steps of:

delivering a second stimulation through the at least one electrode to the neurological motor point of the human; and

changing a central nervous system maladaptive neuroplasticity.
