Innovative Technique Can End Chronic Pain Without Drugs
The novel technique combines two procedures. One is an implanted electronic device called a dorsal column (spinal cord) stimulator and the other is a technology known as peripheral nerve field stimulation (PNFS).
"Patients can have the best of both worlds: relief from leg and back pain they can't get even with the strongest pain medications," said Eugene G. Lipov, MD, Director of Pain Research at the Northwest Community Hospital, Arlington Heights, Ill.
The implantable dorsal column stimulators stop pain signals from reaching the brain, and the peripheral nerve field stimulation focuses on shutting off pain signals further away from the spinal column.
Together, the two effectively block the body's pain signals from the legs and back to the brain.
So how does this procedure work? Well, the hybrid stimulator, which is approximately the size of a small cell phone, is implanted subcutaneously (under the skin) in the abdominal wall, side of the back, or in the upper hip area.
Typically, three electrical leads connected to the stimulator unit are then implanted in areas of the lower back and leg where the patient has felt the most pain.
The patient can then control the pain by placing a small remote control device over the implanted stimulator.

There are much better methods already available than this messy method of implanting a device inside the body.
