In the world of pain relief treatment options, spinal cord stimulation is successful for many people who suffer with chronic back and lower extremity pain resulting from nerve damage. With this therapy, electrical impulses (instead of medication) block pain signals normally detected by the brain.

"A small lead wire is surgically implanted alongside the spinal cord and attached to a stimulator implanted in the buttock or abdomen," explains Joel W. Ray, MD, FACS, neurosurgeon on staff at Saint Francis Medical Center. "Once the stimulation system is activated, low-level electrical signals are transmitted through the lead wire to the spinal cord – preventing pain signals from reaching the brain."

Advances in spinal cord stimulation technology allow those suffering from chronic pain to better manage their pain. Using a magnetic remote control, patients can turn the current on and off to adjust the level of pain relief. The sensation derived from the stimulator is different for everyone, although most people describe it as a pleasant, tingly feeling.

Patients can expect some pain and swelling at the incision site and the receiver implant area that may last from a few days to a couple of weeks. Immediately following the outpatient procedure, patients need to avoid lifting, bending, stretching and twisting. Light exercise, such as walking, is encouraged to build strength and help relieve pain.

"Most physicians recommend a trial period and implant a temporary stimulator," says Ray. "This enables patients to determine if it provides satisfactory pain relief. If it works, a permanent stimulation system can be implanted."

Not everyone is a candidate for spinal cord stimulation therapy, but it is considered when conservative treatments are not successful and surgery is not likely to help. Although not guaranteed to alleviate all discomfort, most patients report a 50 percent to 70 percent decrease in pain – enabling them to return to a more active life style.
