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 ### Claim 1 An electrical stimulation system comprising: an intramuscular lead; at least one electrode insertable into a patient, the at least one electrode operatively coupled with the intramuscular lead; an electrical stimulator operatively coupled with the intramuscular lead, wherein the electrical stimulator delivers electrical stimulation through the at least one electrode to produce a muscle contraction in a target area providing physiologic activation of muscle spindles and golgi tendon organs and afferent input to a central nervous system of the patient to treat pain. ### Claim 2 (depends on 1) The electrical stimulation system of claim 1, wherein the at least one electrode is formed as part of the intramuscular lead. ### Claim 3 (depends on 2) The electrical stimulation system of claim 2, wherein the at least one electrode extends from a conductor attached with the intramuscular lead. ### Claim 4 (depends on 1) The electrical stimulation system of claim 1, wherein the lead includes a portion having an insulated body and the at least one electrode is formed from a portion of the intramuscular lead free of the insulated body. ### Claim 5 (depends on 1) The electrical stimulation system of claim 1, wherein the electrical stimulator is external to the patient. ### Claim 6 (depends on 1) The electrical stimulation system of claim 1, wherein the electrical stimulator is implanted in the patient. ### Claim 7 (depends on 1) The electrical stimulation system of claim 1, wherein the intramuscular lead comprises an insulated coiled portion. ### Claim 8 (depends on 1) The electrical system of claim 1 further comprising an introducer needle configured to percutaneously insert the intramuscular lead. ### Claim 9 (depends on 1) The electrical system of claim 1, wherein a parameter of the electrical stimulation delivered through the at least one electrode comprises a frequency of between 5 HZ and 25 HZ. ### Claim 10 (depends on 1) The electrical system of claim 1, wherein a parameter of the electrical stimulation delivered through the at least one electrode comprises a pulse duration of between 20 microseconds and 200 microseconds. ### Claim 11 (depends on 1) The electrical system of claim 1, wherein a parameter of the electrical stimulation delivered through the at least one electrode comprises an amplitude of between 0.1 mA and 20 mA. ### Claim 12 (depends on 1) The electrical system of claim 1, wherein the at least one electrode comprises a single electrode. ### Claim 13 An electrical stimulation system comprising: an intramuscular lead;
