1. A method of providing extraforaminal electrical stimulation to at least one dorsal root and dorsal root ganglion to provide analgesia to a patient in need thereof, the method comprising:
delivering electrical current from at least one electrical stimulation lead implanted in an extraforaminal area of the spine of a patient in proximity to at least dorsal root and dorsal root ganglion in a target region of the patient to thereby provide analgesia to the patient, wherein the electrical current is delivered unidirectional through the musculature of the patient into the dorsal root and dorsal root ganglion.
