What a Physical Therapist
Says About Heat Therapy
Consistent heat to the joint helps with circulation and keeps the tissue from stiffening up. For people who wake up stiff in the morning — it can make a real difference in how the day starts.

real recovery.
Three clinically-backed mechanisms. One device. No appointments, no subscriptions — just daily recovery on your terms.
Unlimited recovery sessions.
Light That Goes Deeper Than You Think.
Most knee wraps stop at compression. The Athrx K-PRO uses 660nm and 850nm wavelengths — clinically studied frequencies that penetrate deep into tissue to support real recovery at a cellular level.
Therapeutic Wavelength Window
Works primarily on surface tissue — skin, superficial muscles, blood vessels. Reduces surface-level inflammation and improves circulation near the joint.
Penetrates 5cm deep into muscle, joints, tendons, and bone — reaching the tissue where chronic knee damage actually occurs.
Reduces Inflammation
Red light therapy reduces pro-inflammatory cytokines in joint tissue. Less inflammation means less pain, faster recovery, and improved range of motion over time.
Boosts Cell Energy
Red and near-infrared light stimulates mitochondria to produce more ATP. More cellular energy means faster tissue repair and regeneration at the joint level.
Improves Circulation
Light therapy promotes nitric oxide release, dilating blood vessels and increasing local blood flow — delivering oxygen and nutrients directly to damaged tissue.
Supports Joint Health
Studies show red light therapy helps protect cartilage and support collagen production. For knees under daily wear and tear, this means long-term support — not just short-term relief.
Speeds Up Recovery
Red light reduces oxidative stress and promotes faster muscle recovery. After training or a long day on your feet, your knees bounce back faster.
Relieves Chronic Pain
850nm NIR penetrates 5cm deep — reaching tendons, ligaments, and cartilage. Regular use has been linked to significant, lasting reductions in chronic knee pain.
The Science
Why 660nm
& 850nm?
Not all light is created equal. These two specific wavelengths are called the "therapeutic window" — frequencies that pass through skin and muscle without being absorbed or reflected, reaching the tissue that actually needs treatment.
660nm (Red Light) works on surface tissue — the wavelength most associated with reducing inflammation and improving circulation near the skin.
850nm (Near-Infrared) goes deeper. It reaches joints, tendons, and bone — responsible for the deep tissue recovery effects that make this technology so effective for chronic joint conditions.

How It Works
Step 01
Wrap & Secure
Place the K-PRO over your knee and adjust the fit. Built-in LEDs sit flush against the skin for maximum light penetration.
Step 02
Select Your Mode
Choose your preferred heat level (1–5) and LED frequency mode — 5Hz, 10Hz, or 40Hz — or run both together for full recovery.
Step 03
20-Minute Session
Sit back and let the therapy work. 15–20 minutes per session is all it takes. Use daily, post-workout, or whenever your knees need it.
Step 04
Feel the Difference
Most users notice reduced stiffness and improved comfort within the first few sessions. Consistent use compounds results over time.
Your knees deserve
better recovery.

Why
Athrx
We focus on one thing: helping your body recover so you can keep moving, training, and performing without slowing down.
Most knee supports offer short-term relief or feel bulky, uncomfortable, and restrictive. Others rely on cheap materials or one-size-fits-all solutions that don't hold up with real, everyday use. That's not good enough.
Our recovery wraps are designed to support real recovery, not just temporary comfort. By combining targeted heat therapy with clinical-grade red light therapy, we help ease knee pain, reduce stiffness, improve circulation, and support recovery after workouts, long days on your feet, or everyday movement.
Every detail is built with consistency in mind — adjustable fit, comfortable materials, and a cordless, rechargeable design that fits seamlessly into your routine. No complicated setups. No unnecessary features.
We believe recovery should be simple, effective, and reliable — something you actually use, not something that ends up forgotten in a drawer.
When you choose Athrx, you're choosing smart recovery, thoughtful design, and support you can rely on day after day.

Let customers speak for us
First impression is very good, flexible and easy to use. I do miss a more comprehensive user guide, but found some relevant information online.
Bought it for my wife who has knee pain. She was skeptical at first but now swears by it and uses it almost daily. The red light heat therapy has made a real difference for her knee stiffness and pain.
It worked so well for my knee that we ordered a second one. The infrared red light therapy combined with heat is very effective for pain relief and recovery. Cannot recommend this highly enough.
Have had daily constant aches and pains with one knee. I used this about an hour a day for three days while sitting at a desk or in a chair watching tv. Haven't had any more issues with aches since then and this brace provided long term relief. Well worth the cost rather than using creams and sprays.
I've been using the Red Light Therapy Belt for a few weeks now, and I'm genuinely impressed by how effective and convenient it is. Whether you're dealing with muscle soreness, joint pain, or just looking to improve circulation and skin health, this device delivers noticeable results. The combination of 660nm red light and 850nm near-infrared light targets both surface-level skin and deeper tissue. I felt a soothing warmth almost immediately.
I've been using this red light therapy belt for a few days now and it has honestly surprised me. It's very comfortable, easy to adjust, and fits perfectly around the body. The gentle warmth feels great and helps relax the area you're targeting. I'm using it mainly for lower back and abdominal muscle pain, and I've noticed a fast improvement after each session. The material is soft, doesn't irritate the skin, and the product feels high-quality overall. If you're looking for a practical and effective solution, I'd definitely recommend it.
I have several red light therapy pads. And this one is really good. I like its size, the strength and the level of warming is quite comfortable. The controller allows a choice between the 660 and 850 wavelengths and offers 4 levels of strength. It also has a timer.
I have just been using it for just a week. I'm going to use it on my worst knee that's ready for a knee replacement so that I can better evaluate it. So far it seems to be helping. My good knee is hurting more than my bad knee now. It's very easy to use.
I did a lot of research before I bought this belt. Two of my friends also bought this belt and raved about how good it was. The size is perfect. Covers from my hip to my knee which is where I have my issues. It has many selections for heat and time. I would recommend this belt to anyone in pain. It has really helped me. They also have excellent customer service.
Perfect sized light therapy device. Can use on back and legs. Perfect red light waves. Ensuring good use and pain reduction.
The BEST thing I noticed with this knee brace was that my knees have stopped creaking and crunching when I wake up and walk down the stairs! So that's a win for sure. The heat on high was a nice feature and the vibration may be helpful with increasing blood flow to a possible injury. The vibration and warm heat made this item feel therapeutic overall.
Very happy with the product so far. The heat and red light has reduced swelling and is very soothing. The massage setting is a little loud and my knee doesn't fit quite well in it but that's not a big deal to me. Overall very happy and will continue to use this after surgery as well.
Was a bit dubious but hubby's been using it on his sore knees and have had relief. Of course he needs to keep using it. Also bought one for mum and she said that swellings around her ankle had slightly reduced and she's not having to take painkillers as often. Have recommended it to others. Use is pretty self explanatory - strap and switch on.
I love that it gently warms the area and that you can use it for multiple locations. Here is a picture of using it on my shoulder although i think against bare skin works best. Love the extension strap. Seems to be very good quality. Comfortable to use.
After using this red light device twice a day for about a week, I started to notice an improvement in discomfort in my knees. Have had it for a month now and getting continued improvement. Recommend this to anyone with sore knees.
