High frequency electric stimulation of the spinal cord may alleviate acute chronic back pain more efficiently than traditional low frequency stimulation, a brand new study finds.
The device — called the Senza system — reduced back and leg pain scores by at least half.
Other and senza spinal cord stimulators provide mild electrical stimulation to the nerves in the spinal cord that help interrupt pain signals to the mind, in accordance with the Senza web site. Electrodes with lead cables are put near the spinal cord, and a device that includes the batteries is planted under your skin.
Low frequency apparatus cause a constant tingling across the patients' back and legs (paresthesia), Kapural said. "The tingling can grow in strength and can shock people.
This new system, however, uses high-frequency spinal stimulus it suppresses the nerves that raise pain signals traveling to the brain, and that individuals can not feel, Kapural described.
This new study reported two years of follow up comparing the Senza system with conventional stimulus.
Among people that have leg pain, 73 percent of those had alleviation, compared with 49 percent of those using low frequency stimulus, the findings demonstrated.
On a scale of 0 to 10, back pain was reduced a mean compared to 3 points for conventional stimulation by the Senza system. Additionally, about 60 percent of patients were "quite satisfied" with the Senza system, compared to 40 percent with normal stimulation.
The Senza system is accessible and prices — including the operation to plant it and the unit — are about $30,000, which is the same as conventional spinal stimulus, Kapural said. Most insurance covers the prices including Medicare, he said.
The lead wires change, and side effects include mild irritation at the site of the implant and must be repositioned, Kapural said at back pain discussion forum
