The Problem That Changed Everything

In the early 1990s, NASA scientists faced a problem that no one had encountered before: in zero gravity, the human body struggles to heal itself. Wounds healed slowly. Muscles wasted away. Joints deteriorated. Astronauts were returning from space in significantly worse physical condition than when they left.

The cause? Without gravity and sunlight, the body's cells lose the energy signals they need to repair and regenerate tissue.

NASA needed a solution — and they found one in light.

Researchers at the Marshall Space Flight Center discovered that specific wavelengths of red and near-infrared light could stimulate cellular energy production, accelerate tissue healing, and reduce inflammation — even in the extreme conditions of space.

What started as a solution for astronauts quickly attracted the attention of sports medicine doctors, physical therapists, and pain researchers around the world. Decades of peer-reviewed studies followed — all pointing to the same conclusion: red light therapy works at the cellular level to reduce pain, fight inflammation, and support real tissue recovery.

What The Studies Actually Show

Red light therapy at 660nm and 850nm wavelengths has been studied in hundreds of peer-reviewed clinical trials. Here's what the science consistently demonstrates:

Clinic-Grade Therapy. Zero Appointments.

Until recently, getting access to therapeutic-grade red light therapy meant booking expensive sessions at physiotherapy clinics or sports medicine centres — at $100 or more per visit.

The Athrx K-PRO was built to change that. By embedding the same clinically-studied dual wavelengths (660nm + 850nm) directly into a wearable knee wrap, it delivers targeted therapy exactly where your knee needs it — while you sit on the couch, read, or watch television.
