UC San Diego Health Center takes the lead in implanting a new device for the treatment of chronic back pain in the country – mahrgan

The University of California San Diego Health Center provides more options for people suffering from chronic back pain. It has completed the first operation in the country and implanted a device that uses nerve stimulation in the form of electrical impulses to stabilize the lower back. The key nerves and muscles.

The ReActive8 implantable nerve stimulation system manufactured by Mainstay Medical is placed on the lower back. A pair of stimulation leads are located on the nerves that are responsible for stabilizing the lumbar multifidus muscle in the lower back.

Krishnan Chakravarthy, MD, director of clinical pain research at the University of California, San Diego Pain Medicine Health Center and assistant clinical professor at the University of California at San Francisco, said: “We have seen incredible innovations in the use of neuromodulation to address chronic pain in a more personalized approach. Diego Medical School. “We learned that over time, patients with mechanical back pain experience degeneration of the multifidus muscle-a series of small triangular muscle bundles located on either side of the spine. By targeting this muscle with nerve stimulation, we can not only relieve pain, but also restore function. “

According to the Centers for Disease Control and Prevention, one in four adults in the United States suffers from chronic back pain, a disease that causes more disability than any other disease worldwide.

The implantation of the new device is performed in an outpatient setting, and the time required does not exceed one hour. During the operation, the device is about the size of a small pager and is placed on the lower back. A pair of stimulation wires are located on the nerves that innervate the lumbar multifidus muscle and are responsible for stabilizing the lower back.

After the operation, the patient received 30 minutes of directed nerve stimulation every day, twice a day, to contract and strengthen the multifidus muscle. Stimulus is applied via a patient-controlled remote control connected to the device lead.

“We stimulate these muscles with electric current to activate these muscles, which can improve a person’s low back pain, but more importantly, it helps them restore the core stabilizer of the lower back,” Chakravarthy said. “In clinical trials of this device, most patients observed significant improvement in pain and function after just three months, and the lasting effect lasted for nearly four years.”

According to Chakravarthy, this treatment demonstrates a paradigm shift in how to use pain therapy and emphasizes the importance of restorative neurostimulation. Currently, most patients with chronic pain rely on drugs for relief, including opioids.

Chakravarthy said: “Traditionally, chronic pain is controlled by medication and conservative injection therapy, but they have their limitations.” “What we are seeing now is the provision of implantable, minimally invasive non-opioids through innovation. Pain treatment alternatives redefine the field of pain management by providing patients with more personalized options, thereby having a positive impact.”

The Pain Management Center of the University of California San Diego Health Center provides advanced pain treatment programs in a compassionate and supportive environment. If you suffer from chronic pain, please consult your primary care doctor for help and treatment options.
