HFX Neuromodulation

HF10 (10 kHz) Spinal Cord Stimulation — HFX®

Paresthesia‑free relief for chronic nerve pain — offered in Fox River Grove, IL

What is HFX? 

High‑frequency (10 kHz) spinal cord stimulation—often called HFX®—is an FDA‑approved therapy that gently modulates pain signals along the spinal cord without creating tingling sensations (paresthesias). For carefully selected patients, HFX can reduce chronic nerve‑related pain and improve activity, sleep, and quality of life when medications, injections, or surgery have not provided adequate relief.

How effective is HFX? 

  • In well selected patients, HFX can be highly effective long term. 
  • About 8 in 10 people with chronic pain reported their pain decreased by half or more after HFX in clinical and real‑world studies.
  • In one study of chronic back pain (n=156), average pain scores improved from 7.4 before HFX to 2.4 with therapy.
  • Over 100,000 patients have received HFX worldwide.

Individual results vary; we’ll personalize expectations based on your history and goals.

Common Conditions & Indications

HFX neuromodulation may be considered when pain has persisted > 6 months and conservative care has not provided enough relief. Typical indications include:

  • Chronic low back and/or leg pain (with or without prior spine surgery)
  • Radiculopathy/sciatica (nerve root irritation)
  • Failed Back Surgery Syndrome (FBSS) / post‑laminectomy pain
  • Complex Regional Pain Syndrome (CRPS I/II)
  • Painful Diabetic Peripheral Neuropathy (PDN) 
  • Peripheral neuropathic pain (e.g., post‑surgical or post‑traumatic nerve pain)

Am I a Candidate?

You may be a good candidate if most of the following apply:

  • Pain is primarily neuropathic (burning, shooting, electric, pins‑and‑needles) and limits function
  • Symptoms have lasted > 6 months and failed conservative care (PT, medications, injections)
  • You are not a candidate for—or did not benefit from—spine surgery
  • No active infection, untreated bleeding disorder, or contraindicated implanted devices
  • Completed a full diagnostic consultation to ensure no limiting factors are present. 
  • Medical factors are optimized prior to pursuing a temporary trial (i.e. blood sugar control, blood pressure, tobacco cessation, anticoagulation plan if on blood thinners, etc). 
  • Willing to undergo trial of HFX with a temporary device for 5-7 days before committing to a longer term implant.

The Work‑Up & Screening Process

  1. After the 3-7 day trial period, the trial leads are removed in the clinic. If the trial meets your goals (typically ≥50% improvement in pain and/or function), we discuss a long-term implant. If not, we review alternative treatments or next steps.
  2. Specialist Consultation: We will perform a comprehensive and thorough review of your past medical history and pain management history including review of prior consultations, diagnostic testing, and prior interventions/surgeries that have been tried. During this time we will also evaluate if neuromodulation is appropriate for your type of pain and set clear expectations. 
  3. Standard Screening: We may request updated MRI imaging of the spine to ensure that the procedure is able to be safely performed. It is also customary for patients to have a consultation with a psychologist to ensure we are addressing all components of your pain condition. 
  4. HFX Trial (outpatient, 30-45 minutes): We perform the HFX trial in our state of the art office based procedure suite under light sedation by our board certified anesthesia team. The procedure is done under real time image guidance with an X-ray machine for precision and safety. During the trial we access the epidural space with a small needle similar to an epidural steroid injection; however, instead of injecting steroid medication we thread one or two flexible leads into the epidural space which connect to an external battery that sits on the skin. The procedure typically takes 30-45 minutes and you go home the same day.
  5. Clinic Follow-up / Lead Pull : After the 3-7 day trial period, the trial leads are removed in the clinic. If the trial meets your goals (typically ≥50% improvement in pain and/or function), we discuss a long-term implant. If not, we review alternative treatments or next steps.

What the HFX Trial is Like (Temporary Test)

Purpose: To “test‑drive” therapy for 5–7 days at home.

Setting & Anesthesia: Outpatient procedure room; local anesthetic with optional light sedation.

Steps: 

  1. Under fluoroscopy (live X‑ray), one or two thin flexible leads are placed through a needle into the epidural space over the appropriate spinal levels corresponding with your area of pain. 
  2. Leads are secured to the skin and connected to a small external battery worn on a belt or bandage.
  3. Our team programs several HFX settings while you are awake and comfortable.
  4. You go home the same day with instructions, a diary to track pain/function/sleep, and 24/7 support.

Activity & Care:

  • Keep dressings dry; avoid bending/twisting/lifting >10 lb to prevent lead movement.
  • Continue normal light activities to gauge real‑world benefit.

Assessing Success:

  • We look for meaningful improvement in pain and function (often ≥50% pain relief and/or clear gains in activity and sleep).
  • If the trial is beneficial, we schedule the permanent implant. If not, the leads are removed in clinic and other options are reviewed.

FAQs

How is HFX different from traditional SCS?
HFX delivers high‑frequency (10 kHz) stimulation designed to relieve pain without the tingling sensations required by older SCS systems. Many patients prefer this paresthesia‑free experience
Is HFX covered by insurance?
Yes. Coverage is common among major plans, including Medicare and Tricare, when medical criteria are met and the trial shows benefit. We confirm coverage and obtain prior authorization.
Can I get an MRI with HFX?
Yes—within conditional parameters. Most patients can have full‑body MRI when model‑specific safety rules are followed. We’ll give you an MRI card and instructions.
How long does the battery last?
The implant battery is designed to last 10+ years. There can be some variability based on the energy requirement of your device.
Will I feel the device?
You won’t feel the stimulation. You may feel the small battery under the skin, especially when sitting against a hard surface, but most people quickly get used to it.
Can I travel or exercise with it?
Yes—after healing and with your clinician’s guidance. Many people return to walking, light strength work, and travel. Contact sports and extreme twisting/lifting are discouraged.
What if my pain pattern changes?
Your device can be reprogrammed. We can also adjust lead positioning in rare cases where anatomy or pain patterns evolve.
What about other options—RFA, injections, or surgery?
We consider all evidence‑based options. HFX is typically chosen when conservative care has been exhausted and surgery is not desired or helpful.
How long does relief last?
Responses vary. Neuromodulation is adjustable and can continue to provide benefit long‑term with proper follow‑up and programming.
