Have you tried pain medications, physical therapy, spinal injections and even back surgery with no relief?

If so, you may be a candidate for Nevro’s HF10 therapy.

Unlike traditional spinal cord stimulation (SCS), Nevro’s Senza® system does not mask pain—it actually reduces it.

We consider HF10 Therapy a success when:

  • Your pain is reduced by at least 50 percent
  • You are able to walk, carry groceries and perform other normal activities with less pain
  • You no longer have to take pain medication just to go to work or enjoy time with your family
  • You are able to get a good night’s sleep without waking up in pain



“HF10 Therapy is my best friend; I’m no longer hiding behind the pain.”

Before HF10, Terri didn’t think she’d ever have a day when pain wasn’t the first thing on her mind. Now she can be more spontaneous with her activities.*

FDA Approved

HF10 therapy is approved by the FDA for the treatment of chronic lower back and leg pain. Extensive testing shows that HF10 therapy provides up to 80 percent relief.

Why HF10 Therapy?

Unlike traditional SCS, HF10 therapy uses innovative spinal cord stimulation technology to block pain, resulting in continuous relief without any annoying buzzing or tingling sensations.

When compared to traditional SCS, HF10 therapy has many advantages.

  • The device can stay on while you sleep and drive, resulting in long-lasting pain relief.
  • You get to decide when to turn the device on and off, giving you total control of your therapy.
  • Because the device does not cause annoying shocks, your sleep quality is likely to improve.

In clinical trials, 84.3% of patients experienced
improvement in back pain after just three months.*
