Bio-Adaptive Neurostimulation
Neurostimulation that adapts to the body
InterX continuously reads the body's changing response and adapts its stimulation in real time, helping direct stimulation where the body is most ready to receive it. Designed to support drug-free pain relief and functional recovery. Trusted by clinicians, elite athletes, and leading institutions.

Trusted where the stakes are highest
Meet Trayvon Bromell. Five-time global medalist. Two-time World Champion. One of the fastest men in the world.
After more than fifteen years competing at an elite level, Trayvon Bromell has learned that performance is about more than what happens on the track. Longevity depends on more than training alone. The ones who stay at the top understand that recovery is what lets them keep showing up, competing, and performing year after year.
"Recovery is part of the work," Mr. Bromell emphasized during a recent interview. That is why InterX has become part of Trayvon's recovery routine, helping him maintain his body, stay consistent, and keep performing at the highest level.
Longevity isn't built on talent alone. It is built on the ability to recover, adapt, and be ready to do it again tomorrow.

InterX® listens first
Conventional e-stim delivers a fixed output, no matter how the body responds. InterX works differently. It continuously reads the body's changing response and adapts its stimulation in real time. As the body's response changes, so does the stimulation.
That continuous feedback creates an ongoing conversation with the body throughout treatment.
Non-invasive. Drug-free. Designed to work with the body, not over it.
How it works
Scan → Target → Dynamic is one continuous adaptive process. Together, these three steps allow InterX to continuously respond to the body's changing response throughout treatment.
Step 1: SCAN
Locate neurologically active treatment sites by reading changes in the skin's impedance, identifying where the body is most responsive to stimulation.
Step 2: TARGET
Deliver precise, high-density stimulation where the body responds most, continuously adapting as the body's response changes.
Step 3: DYNAMIC
Continue treatment through movement, allowing treatment to adapt during functional activity rather than only at rest.
Why responsiveness matters
Backed by published clinical research
The technology behind InterX has been evaluated in published clinical research. In the clinical literature, where it is studied as non-invasive interactive neurostimulation (NIN), InterX has been evaluated in controlled clinical trials, demonstrating meaningful outcomes across multiple conditions.

Razzano et al., The Journal of Foot & Ankle Surgery, 2018
Athletes returned to sport faster after an acute ankle sprain, and leaned on anti-inflammatories less, in a Level 1 randomized controlled trial.

Razzano et al., 2017
For chronic plantar fasciitis, InterX outperformed shockwave therapy on function, pain, and patient satisfaction.

Nigam et al., Journal of Orthopaedic Surgery and Research, 2011
After total knee replacement, patients had less pain and recovered range of motion faster when InterX was added to standard care.
