Introduction
At Red Butte Pain Solutions, we’re always exploring new options for effective pain relief, including spinal cord stimulator (SCS) devices. Many of you may have read our recent post on Differential Targeted Multiplex (DTM) stimulation, where we covered its unique approach for managing chronic pain. But DTM isn’t the only advanced spinal cord stimulation option available. Today, let’s discuss High-Frequency (HFX) spinal cord stimulator technology, another exciting development in pain management.
When it comes to treating chronic pain, HFX spinal cord stimulator technology has made quite a name for itself. Back in the day, most spinal cord stimulators followed a paresthesia model, but now, with options like DTM and HFX, there’s more choice for patients with different pain types and intensities. In this post, we’ll dive into the science behind the HFX spinal cord stimulator, compare it to conventional and DTM stimulation, and look at the evidence supporting its effectiveness.
What Is High-Frequency (HFX) Spinal Cord Stimulator Technology?
High-frequency stimulation, often referred to as HFX, is a specific type of spinal cord stimulation that operates at a much higher frequency than traditional SCS devices. Standard spinal cord stimulators usually operate at around 40 to 60 Hz, while HFX typically operates at frequencies around 10,000 Hz or higher. This increased frequency is a significant shift in how pain signals are blocked, allowing HFX spinal cord stimulators to offer different benefits compared to traditional models.
The key advantage? HFX spinal cord stimulator devices often eliminate the “tingling” or paresthesia associated with traditional SCS. For many patients, this makes HFX a more comfortable and natural-feeling option for chronic pain relief. And, thanks to recent research, we know that HFX spinal cord stimulation may also be superior to conventional devices for long-term pain reduction.
How Does HFX Differ from Conventional Spinal Cord Stimulators?
Let’s break down some of the core differences between HFX and conventional spinal cord stimulator technology:
1. Frequency
The most apparent difference is in the frequency. Traditional spinal cord stimulators operate at lower frequencies, often between 40 and 60 Hz, while HFX reaches much higher frequencies, around 10,000 Hz or more. This high frequency is a game-changer because it directly affects how pain signals are blocked.
2. Paresthesia-Free Experience
Traditional spinal cord stimulators often cause a tingling or buzzing sensation called paresthesia. While some patients find this feeling reassuring, others find it distracting or uncomfortable. HFX, on the other hand, works without causing paresthesia. This makes it a more appealing spinal cord stimulator option for patients who prefer pain relief without added sensations.
3. Mechanism of Action
Traditional spinal cord stimulators work by “scrambling” pain signals with a consistent, low-frequency stimulation. HFX, however, delivers such rapid signals that it effectively shuts down pain pathways without needing to rely on paresthesia. This difference in mechanism can lead to a more seamless pain relief experience for patients.
4. Effectiveness for Different Pain Types
Studies suggest that HFX stimulation may offer better results than traditional models, especially for chronic back and leg pain. This makes HFX a good choice for patients who haven’t responded as well to conventional spinal cord stimulator devices or those who want an alternative without the tingling sensation.
HFX vs. DTM Spinal Cord Stimulators
If you’re wondering how HFX stacks up against DTM (Differential Targeted Multiplex) spinal cord stimulator technology, let’s look at some of the main contrasts. Both HFX and DTM are considered advanced options in spinal cord stimulators, but they take distinct approaches.
How DTM Spinal Cord Stimulator Technology Works
As discussed in our previous blog post, DTM targets not only the spinal cord but also glial cells surrounding neurons. These glial cells are involved in pain processing, and by targeting them, DTM addresses both neural and non-neural contributors to chronic pain. This dual-action approach makes DTM effective for patients with glial cell-related pain, such as those with complex regional pain syndrome (CRPS).
Key Differences Between HFX and DTM Spinal Cord Stimulators
| Feature | HFX Spinal Cord Stimulator | DTM Spinal Cord Stimulator |
|---|---|---|
| Frequency | High frequency (around 10,000 Hz) | Standard SCS frequency |
| Target | Primarily spinal cord | Spinal cord and glial cells |
| Paresthesia-Free | Yes | Not necessarily |
| Pain Types | Back and leg pain | Complex pain types, CRPS |
The main takeaway here is that HFX and DTM spinal cord stimulators are tailored for different kinds of pain. While DTM offers a broader approach targeting both neurons and glial cells, HFX provides a simpler, high-frequency option ideal for those seeking paresthesia-free relief.
Evidence Supporting HFX Spinal Cord Stimulators
Let’s dive into the evidence. Research on HFX spinal cord stimulator devices is promising, particularly in showing that they may be more effective than conventional stimulators for certain types of chronic pain.
Pain Reduction in Back and Leg Pain
A study published in the Journal of Pain Research compared HFX spinal cord stimulators to conventional SCS in patients with chronic back and leg pain. Results showed that patients using HFX reported significantly greater pain relief than those with traditional SCS. The study found that 74% of patients with HFX experienced at least 50% pain reduction, while only 49% of those with conventional spinal cord stimulators saw similar results.
Long-Term Benefits
Another study followed patients over 12 months and observed that the effectiveness of HFX spinal cord stimulators didn’t diminish over time. This long-lasting relief is a major benefit, as some patients report reduced effectiveness of traditional devices over time.
Quality of Life Improvements
HFX has also been shown to improve quality of life for many patients. Because it eliminates paresthesia, HFX allows patients to engage in activities without distraction. In a quality-of-life survey, HFX patients reported higher levels of comfort and satisfaction with their spinal cord stimulator compared to those with conventional devices.
Is HFX Right for You?
Choosing the best spinal cord stimulator therapy can be overwhelming, especially with the increasing number of options. Here’s a quick guide on when HFX may be the ideal choice.
When to Consider HFX Spinal Cord Stimulator Technology
HFX might be a good option if:
- You have chronic back or leg pain. Studies show HFX works well for these pain types.
- You want paresthesia-free stimulation. HFX provides relief without tingling, which some patients prefer.
- Conventional SCS hasn’t provided enough relief. If you’ve tried traditional spinal cord stimulator devices with limited success, HFX may offer the relief you’re seeking.
When to Consider DTM Spinal Cord Stimulator Technology
DTM may be a better fit if:
- Your pain is complex or multi-layered. DTM’s targeting of glial cells makes it effective for certain difficult-to-treat pain conditions.
- You’re open to experiencing paresthesia. Some patients actually find this sensation helpful, so it may not be a drawback for everyone.

Real-World Patient Stories
To illustrate the impact of HFX, here are a couple of real-life stories:
- Susan’s Journey with Failed Back Surgery Syndrome: Susan suffered from failed back surgery syndrome, a condition that left her with chronic back pain even after undergoing surgery. She tried various treatments, including traditional spinal cord stimulator devices, but found no lasting relief. After starting HFX therapy, however, Susan experienced significant pain reduction without the uncomfortable tingling sensations of her previous treatments. Now, she can enjoy daily activities with her family that once seemed impossible, like long walks and even a light exercise routine.
- Eva’s Story with Diabetic Peripheral Neuropathy: Eva, a long-time diabetic, struggled with diabetic peripheral neuropathy—a painful condition that often left her feet numb and burning. The pain had grown so severe that even simple pleasures, like walking her dog, were too difficult. After switching to an HFX spinal cord stimulator, Eva noticed a remarkable improvement in both her pain levels and sensation in her feet. Now, she’s able to walk her dog every day and enjoys the newfound ability to feel and move more comfortably.
