A restorative treatment for mechanical CLBP

The information on this page is intended for Physicians.

ReActiv8® is an effective and durable treatment for your patients with mechanical Chronic Low Back Pain (CLBP) and multifidus muscle dysfunction.

What is ReActiv8?

ReActiv8 Restorative Neurostimulation is a restorative therapy designed to address impaired neuromuscular control and degeneration of the multifidus muscle linked to mechanical chronic low back pain (CLBP). The ReActiv8 system overrides underlying multifidus inhibition by eliciting episodic, isolated contractions which, over time, can facilitate recovery from mechanical CLBP. This therapy can provide an effective treatment solution for your patients with mechanical CLBP.

How is it different?

ReActiv8, the first and only restorative device of its kind, uses a restorative treatment approach that targets underlying multifidus muscle dysfunction. Analgesic (or palliative) treatment options have limited effectiveness and durability in patients with mechanical CLBP. [1]

How does it work?

The ReActiv8 therapy targets the multifidus muscle with electrical pulses delivered through proprietary self-anchoring lead technology placed adjacent to the medial branch of the dorsal ramus. Post procedure, your patient conducts their own at-home therapy twice daily for 30 minutes per session.

Compelling Patient Outcomes

ReActiv8-B clinical trial patient outcomes after five years.

The ReActiv8-B Clinical Trial is an international, multi-center, randomized, active-sham controlled blinded trial comparing the ReActiv8 therapy Treatment Group to an active sham Control Group.

Long-Term Treatment Benefits

  • ReActiv8® provides an effective, durable, and safe treatment option for carefully
    selected patients with intractable CLBP and multifidus muscle dysfunction.
  • Trajectory and durability of clinical benefits are consistent with restoration of
    neuromuscular control and muscle rehabilitation.
  • Restorative neurostimulation does not appear to be susceptible to loss of
    efficacy. (i.e., decreasing effectiveness over time)
  • The safety profile of the therapy remained favorable compared to available
    implantable neurostimulators for the treatment of other types of back pain.
  • An increasing proportion of participants are eliminating or decreasing opioid

Anatomy Overview

Neuromuscular Control: Proprioception and Back Muscles

Mechanical chronic low back pain results from an injury or stress on the tissues surrounding the spine, including soft tissues, muscles, bones, and joints. Often times, this type of pain is due to impaired neuromuscular control and neural inhibition of the multifidus, which is the largest stabilizing muscle in your back.

Pathology Overview

Multifidus Dysfunction: Loss of Neuromuscular Control

Multifidus Dysfunction can result from a loss of neuromuscular control. This can cause a lack of spinal support, leading to uncontrolled loading of spinal joints and discs, resulting in mechanical low back pain.

Procedure Overview

Treat the cause, not the symptoms.

ReActiv8 is implanted underneath the skin during a minimally-invasive outpatient procedure. A generator is connected to two electrical leads, which are positioned to stimulate the nerves that control the multifidus muscle.

Patient Testimonials

ReActiv8 implanters and their clinical staff have seen patients’ lives change after treatment with ReActiv8. Watch their stories below below about their experience with mechanical CLBP.

The following videos contain stories from three of our international patients who experienced remarkable results from the ReActiv8 system. Patients’ stories are theirs only and not indicative of the results for all patients. Patient outcomes will vary. See paragraph below for US indication and product information.


Frequently Asked Questions

Reactiv8 is a treatment for adults with intractable mechanical chronic low back pain associated with multifidus muscle dysfunction, as evidenced by imaging or physiological testing. Candidates for the therapy have failed interventional treatment options including pain medications and physical therapy and are not indicated for spine surgery.

On average, people with CLBP who were treated with ReActiv8 Restorative Neurostimulation therapy had substantial reductions in pain, and improvements in disability and quality of life after one year. Given the restorative nature of the therapy, it may take some time for the pain relief and improvements in function to be experienced by the patient.

To assist in securing coverage from health insurance providers, we offer the ReActiv8 Support and Verification Program (R.S.V.P.) by partnering with experts specialized in working with health insurance companies and our physician partners.
