ReActiv8® for Back Pain

ReActiv8 is an FDA-approved implantable system for adults with chronic low back pain linked to a weakened multifidus muscle. Unlike treatments that focus on masking pain signals, ReActiv8 is designed to help restore the muscle control that supports and stabilizes your lower spine.

This approach is known as restorative neurostimulation. For the right patient, it may help reduce pain and improve the ability to move and stay active over time.

What Is the Multifidus Muscle?

The multifidus is a group of small, deep muscles that run along both sides of the spine. They help keep the lower back stable during everyday movements like bending, lifting, and twisting.

When these muscles stop working properly, often called multifidus dysfunction, the spine can lose some of its support. Over time, this may contribute to ongoing low back pain that doesn't respond to medication or physical therapy.

How Does ReActiv8 Work?

ReActiv8 uses a small device implanted in the lower back. Thin leads are placed near the nerves that control the multifidus muscle. The device sends gentle electrical pulses that cause the muscle to contract, which is designed to help retrain it and improve spinal stability.

Therapy sessions are short and done at home, typically while lying down. You start each session using a handheld remote, usually twice a day.

Are You a Candidate for ReActiv8®?

ReActiv8 may be an option for adults who:

  • Have chronic low back pain that has lasted several months or longer
  • Show signs of multifidus dysfunction, which your physician can evaluate with imaging and testing
  • Have not found enough relief with medication, physical therapy, or other conservative care
  • Are not candidates for spine surgery, or would like to explore other options first

Your physician will complete a thorough evaluation to determine whether ReActiv8 is right for you.

What to Expect During Your Procedure

ReActiv8 is implanted during a minimally invasive outpatient procedure, and most patients go home the same day. Your physician places the thin leads near the nerves that control the multifidus muscle and positions the small device under the skin in the lower back.

After the procedure, your care team will program the system and show you how to start your therapy sessions at home.

Recovery

Most patients return to light daily activities within a few days. For the first several weeks, you will likely be asked to limit bending, twisting, and heavy lifting while the incisions heal. Because ReActiv8 works by retraining muscle, improvement is often gradual. Your care team will follow up with you to track your progress.

Potential Risks

As with any implanted device, ReActiv8 carries some risks. These may include infection, bleeding, discomfort at the incision site, lead movement, or device issues. Your physician will review the risks and benefits with you so you can make an informed decision.

ReActiv8 Physicians

ReActiv8 at Spine & Orthopedic Center is performed by fellowship-trained pain management physician Dr. Kristy Fisher.

Frequently Asked Questions

How is ReActiv8 different from spinal cord stimulation? Spinal cord stimulation works by changing how pain signals travel to the brain. ReActiv8 is designed to help restore control of the muscles that stabilize the lower back.

Is there a trial period? ReActiv8 does not use a trial period like spinal cord stimulation. Your physician will use imaging and an evaluation to determine whether you are a good candidate.

How long are therapy sessions? Sessions are short and done at home, typically twice a day while lying down. Your care team will walk you through your schedule.

Will I feel the stimulation? You may feel the muscle contracting during sessions. Your care team will adjust settings for your comfort.

Will insurance cover ReActiv8? Coverage varies by plan. Our team can help you check your coverage before treatment.
