Still suffering from lower back pain?

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 muscle control and neural inhibition of the multifidus, which is the largest stabilizing muscle in your back. When this neuromuscular inhibition occurs, there can be misalignment of the spine, causing uncontrolled loading and pain.

Could your back pain be due to Multifidus Dysfunction?

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.

Is ReActiv8 right for you?

Complete this health survey to see if you’re a good fit

If you’ve read this far, you’re likely still searching for a long term solution to your back pain. By answering the following questions, we can provide you with general guidance on whether you may be a candidate for ReActiv8.

"*" indicates required fields

Patient Name*
Post Code*
Have you experienced back pain for more than 6 months?*
Is your low back pain worse than your leg pain?*
If you were to rate the level of your day-to-day low back pain on a scale of 0-10, with 0 being very little pain, and 10 being the worst possible pain, how would you rate your average low back pain over the last 7 days?*
Have you tried prescription medication or attempted physical therapy for your low back pain?*
Are you willing to consider a surgical procedure for your low back pain?*
Have you previously had lumbar decompression or lumbar fusion surgery?*
Do you have private health insurance?*

Consent:  By completing the above survey, I consent to Mainstay Medical reviewing this limited health information about me, providing an initial, preliminary assessment about whether ReActiv8 may be a suitable therapy for me, and offering to contact me to provide more information. I understand this does not represent medical advice, opinion, diagnosis, or services in any way, and I must consult with my physician or other health care provider for an actual determination about this product. I also understand that, by providing this information, I am not guaranteed or promised any service or product, nor a final or complete assessment on whether ReActiv8 may be appropriate for my low back pain.

Think Restorative Sooner

ReActiv8 is designed to treat chronic low back pain in patients diagnosed with dysfunction of the multifidus, which is the primary muscle responsible for lumbar spinal stability. ReActiv8 aims to reduce pain and improve related disability and quality of life.

Multifidus Muscle dysfunction

ReActiv8 is implanted in the lower back or upper buttocks during an outpatient procedure.

  • A generator is connected to two electrical leads, which stimulate the nerves that control your multifidus muscle.

  • You control your 30-minute therapy sessions, twice-daily, which can feel like a deep tissue massage.
Long-Term Clinical Outcomes

Pain and Function Improvements

Pain and Function Improvements

~8 out of 10** patients reported substantial improvements*** in pain and/or function.

Opioid Reduction

Opioid reduction represented in vector people symbols

~7 out of 10 patients voluntarily eliminated or reduced their opioid intake.*

*Of the 52 subjects who were on an opioid-containing medication at baseline and had a 5-year visit, 69% either decreased (23%) or discontinued (46%) opioids. In addition, of the 74 patients who were not on opioids at baseline, 72 (97%) remained off opioids at the 5-year visit. Therefore, the efficacy results observed at 5-years are in addition to significant reductions in opioid use.

Graph showing Reduction in Pain

~78.2% (97/124) had a 50% improvement in VAS and / or 20 point at 5 years. 69% of the 52 patients that at baseline were using opioids and were followed to 5 years.

5 Year Data

***Substantial improvement is 50% reduction in Pain measured on visual analogue score and / or a 20 point reduction in Oswestry disability index compared to baseline.

Patients experience long-term improvements in pain and function over time, demonstrating long-term, durable outcomes.

The ReActiv8-B Trial demonstrated a strong safety profile for ReActiv8 (particularly compared to spinal cord stimulators). Among the 204 randomized patients through 5 years of follow-up, there were a reported 8 patients (4%) who experienced serious adverse events (SAEs) related to the device/procedure, with 6 of those having pocket infection requiring explant prior to the 120-day visit. There were no unanticipated device/procedure related AEs and no instances of lead migration reported during this study. Key adverse events included implant pocket pain in 21% of patients with 83% resolved, device overstimulation in 15% of patients with 88% resolved, and lead fracture in 5% of patients which all were resolved with intervention.

Backed by real patients with real results

Many people who were treated for their mechanical chronic low back pain with ReActiv8 have seen a dramatic improvement and were eager to share their stories to give hope to others.

Frequently Asked Questions

The multifidus muscle is the key stabilizing muscle in the lower back. A single injury to the back can cause impaired muscle control of the multifidus. This lack of muscle control can decrease the spine’s functional stability, leaving the spine susceptible to further injury and overloading.

Restoring the neuromuscular control of the multifidus muscle can stabilize the spine, thereby increasing function and decreasing pain.

ReActiv8 is currently listed on the prostheses list. If you are an Australian citizen or permanent resident, Medicare and/or your private health insurance provider may partially or completely cover the costs of your procedure. Consult your physician and/or private health insurer for more information.

ReActiv8 and SCS are different in almost every way. Most importantly, they each target different CLBP patient populations:

• ReActiv8 addresses predominantly musculoskeletal/mechanical/axial nociceptive CLBP.

• SCS addresses predominantly neuropathic CLBP and radiculopathy.

They have a completely different delivery schedule:

• ReActiv8 delivers stimulation to cause repetitive multifidus contractions during two 30-minute sessions daily.

• SCS typically delivers stimulation 24/7 to cover the pain.

On average, people with mechanical CLBP who were treated with ReActiv8 had substantial improvements in pain, disability and quality of life after one year.

Talk to your doctor to see if you are a candidate. ReActiv8 is for patients who have mechanical chronic low back pain, but have not found relief through medical management or physical therapy.
