Infrared therapy isn’t new.
Hospitals have used it for decades in post-surgical recovery and deep tissue rehabilitation.
But here’s what most people don’t realize:
Not all heat is the same.
Surface heat — like heating pads, hot water bottles, or topical creams —
only warms the skin and maybe 1 cm of tissue beneath it.
But the muscles compressing your sciatic nerve?
They sit 4 to 6 cm deep, far beyond the reach of surface heat.
Infrared waves, however, behave differently.
They pass through skin, fat, and connective tissue, delivering warmth directly into deep muscle layers.
A study published in The Journal of Clinical Rehabilitation tested infrared therapy on 847 patients with chronic sciatica.
Half received standard heat therapy, and the other half received infrared.
After 14 days, the results were dramatic:
– Standard heat group: 31% improvement
– Infrared group: 76% improvement
The difference was simple:
Infrared reached the shutdown zones.
But the Michigan team didn’t stop there.
They combined infrared with dual vibration therapy.
Here’s why that matters:
When muscles enter shutdown mode, they develop what’s called protective guarding —
a reflex where the body locks the muscle in place to prevent further injury.
But that locked muscle is exactly what compresses the nerve.
Vibration therapy disrupts the guarding reflex and tricks the muscle into relaxing.
Think of it like this:
Infrared melts the ice.
Vibration breaks the grip.
Together, they free the nerve.
The Michigan team called this combined approach InfraTherm Release™ — a patented technology that combines targeted deep heat with dual-frequency vibrational pulses.
But there was a problem: this therapy was only available at specialized clinics.
Sessions cost between $40 and $80 each. And at least 12 to 20 sessions were needed for lasting results.
That meant an investment of $800 to $1,600 — not counting time spent traveling, scheduling, and waiting in line.
They miniaturized all the InfraTherm Release™ technology into a portable device that anyone can use at home — the FlexTherm™ Max.
The device was engineered to deliver the same clinical parameters as professional sessions:
✓ Calibrated infrared waves for 4-6 cm penetration
✓ Dual-frequency vibration (low for relaxation + high for neural release)
✓ Automatic 20-minute timer per session
✓ Ergonomic design that fits perfectly to the lower back and gluteal region
The goal was simple: democratize access to a technology that actually works.
And make it available to those who need it most — people suffering in silence, who have already spent fortunes without results, who believed there was nothing left to try.
