Methods and devices for treatment of non-neuropathic conditions using electrical stimulation

A method of treating a non-neuropathic condition, the method comprising:

• applying electrical stimulation energy to a dorsolateral funiculus of a patient through one or more electrodes of an implanted electrical stimulation lead to treat the non-neuropathic condition;
• and
• increasing an activation threshold of a side-effect exhibiting neural structure relative to an activation threshold of the dorsolateral funiculus of the patient, wherein the electrical stimulation energy is applied to the dorsolateral funiculus of the patient while the activation threshold of the neural structure relative to the dorsolateral funiculus is increased to treat the non-neuropathic condition without stimulating the neural structure.

A method of treating an inflammatory condition, the method comprising:

• implanting an electrical stimulation lead in an epidural space of the patient near a dorsolateral funiculus of a patient, the electrical stimulation lead comprising a plurality of stimulation electrodes, wherein the electrical stimulation lead is implanted with at least three of the stimulation electrodes disposed lateral of a midline of a spinal cord of the patient in a selected single dorsal-lateral quadrant of the epidural space and adjacent the dorsolateral funiculus of the patient;
• and
• applying electrical stimulation energy to the dorsolateral funiculus of a patient using at least one of the at least three of the stimulation electrodes of the implanted electrical stimulation lead to treat the inflammatory condition.
