Relief Lower Back Pain With Steel Supports And Heat Therapy

Welnax™ is a 360 degree wrap around back brace designed to provide compression, protection and support for the lower back. It relieves lower back pain and improves stability with the use of specially contoured lumbosacral steel and flexible support plates. These plates are removable and can be slotted into a back pocket built into the brace.

How Does It Work?

 

Special double pull tension straps push the support plates against the spine, providing compression and support for the lower back.

The support plates are contoured to follow the spinal curve. This compression aligns the spinerestores the spinal curvatureimproves posture, and helps relieve pinched nerves that could cause sciatica, a pain that runs down the buttocks and legs.

Welnax™ helps to stabilize your lower back, reduce micro-motions at the affected spinal segment, distribute the spinal forces evenly, and spread the weight across the body. It helps limit twisting and bending movements that may aggravate existing injury, or cause new ones. This allows your injury to heal naturally within a shorter period of time.

Who Is It For?

Welnax™ is ideal for individuals experiencing chronic back pain, have sensitive lower backs, or are prone to back injuries.

Whether you're an office worker spending long hours at a desk, involved in physical labor such as constructionmoving, or cleaning, or engaged in your favorite activities like travelbikingdriving, or horseback riding.

It's also great for sports enthusiasts who like runningwalking, or even golf. Homemakers doing houseworkcleaning, or gardening, as well as retirees and seniors, can find support and comfort with Welnax™.

Contoured Lumbosacral Support Plates

The back support plate and side splints add extra strength and pressure to your lower back. The primary plate is specially shaped to match your spine's natural curve, while the two splints are slightly curved to support the quadratus lumborum muscles on both sides of your lower back. This ensures a comfy and snug fit when these supports are pushed against your body.

Both Steel and Plastic Supports

There are both rigid and flexible supports available for your choosing. Welnax™ includes not just one, but two sets of support plates – one in tough steel for sturdy and enhanced compression, perfect for those needing stronger support. The other set is made of flexible plastic, offering more flexibility for movement.

Improve Blood Circulation With Heat Therapy

Welnax™ includes 3 detachable therapy pads to further aid in the recovery process. These pads can be attached to the insides of the brace with Velcro.

1. Self-Heating Pad

This pad contains small tourmaline stones that heat up naturally on contact with the skin. It provides soothing hot compress therapy to help improve blood circulation by dilating the blood vessels in the affected area. This brings nutrients to the affected area, thereby accelerating the healing process and reducing pain, back stiffness and soreness.

2. Breathable Mesh Pad

This pad, made from breathable fabric, includes a pocket for inserting an ice-pack if required. Treating an injury with ice, called cold compress, helps slow down blood flowreducing inflammation and swelling that causes pain.

3. Warm Velvet Pad

This soft velvet pad provides an additional layer of warmth and comfort on cool days.

 

What Can Welnax™ Be Used For

Injury Recovery

Welnax™ can be used to quicken a recovery from an injury. It is especially useful for herniated disk injuries where a straight posture is essential for a faster recovery while keeping pain to a minimum. You can also use it as a post-operative rehabilitative brace to maintain stability and accelerate your healing process after a surgery.

Injury Prevention

Welnax™ can be used even if you have no back injury. It can protect your lower back while you go about your everyday tasks like household choresgardening or even sports. It keeps your back straight as you lift heavy objects or do back-breaking jobs. It constantly reminds you to use the correct technique of bending your knees instead of your back while lifting heavy loads, preventing an injury that you might regret later.

Avoid Risky Surgeries And Expensive Healthcare

Welnax™ was created to help people struggling to cope with rising healthcare costs and avoid the high risks of surgeries.

Did you know...

  • An estimated 112 million (44%) American adults are struggling to pay for healthcare, and more than double that number (93%) feel that what they do pay is not worth the cost.
  • An estimated 20% to 40% of back surgeries fail, with repeated surgeries bearing an even higher risk. Merely 30% of back surgeries achieve success.

Worth the Money
Style: AVR-X2800H
I have had this item for a few weeks now. This is the first high-tech AVR I have purchased. I decided to retire my 25 year old Denon AVR 900. Still works awesome and is in perfect shape. Needed to upgrade to newer technology. Many will frown at this, but I initially sent back an Onkyo TX-RZ30. I just found that I did not feel comfortable with the technology, but it is an exceptional receiver. I decided to go with the Denon AVR-X2800H. I just feel more confident with the Denon layout and setup guide. I have not been dissapointed. I very reluctantly ordered a refurshed model. I can tell no different, even in the packaging. Looked totally brand new. I will say that I am still learning all of the setup, but so as for ease of general setup and assigning speakers it has been very user friendly. I was curious to see the sound difference with music between my 25 year old Denon and the new Denon 2800. I was not dissapointed. I have a smaller room for the AVR, so I am using Klipsch 600II, Klipsch 400C center speaker, Fluance Signature Series bookshelf speakers, and Polk OWM3 rear speakers. The receiver push all these speaker quite easily and efficiently. I would definatly recommend this Denon model. Can it last 25 years plus like my other Denon. Only time will tell.

Please Read for Troubleshooting Info
Style: AVR-X2800H
I purchased a refurbished device and at first it worked fine. Then it started having a lot of trouble on power up locking into my DirectTV cable signal. It kept powering up my Blu-ray player and accessing its menu, even though I had not selected it and there was no disc loaded. I became frustrated enough that I returned the device. Wish I hadn't as it was a nice home theater system. To make a long story short, I bought another brand of receiver (for more money) and continued to have the exact same problem. Finally, a Google search found a troubleshooting solution on reddit. Many reddit users suggested turning off the HDMI CEC control. This was easier said than done, as this HDMI CEC control setting was not found in the Denon receiver menus. It was found in the setup menu for the Blu-ray player. Once I found the proper setting and turned it off the receiver was no longer confused and trying to access the Blu-ray player upon power up. It locked in on the DirertTV signal and was rock solid. I wish I had learned this solution earlier and had kept this nice receiver. I'm so bummed.

"factory certified" broken receiver
Style: AVR-X2800H
So I call b.s. on these. Here's why. I got a unit with a broken IR receiver. I cannot imagine a real factory certification process that doesn't involve making sure the unit responds to a remote control. This one of the first things you would try to make sure something works.

Great upgrade to my Denon AVR-X2400H
Style: AVR-X2800H
Good audio and video quality - a great upgrade to my lightning-zapped AVR-X2400H. Audio analyzer works better than the earlier version, but still required some tweaking of the rear surround (reduce) and Front Center (increase) channels. I had to raise the input trim levels for my HDMI 1&2 for TiVo and Roku to get the output level active in the first 1/3 of the volume control range. Bluetooth feed to external headphones works well but does not have the same volume level range as the main audio. Audio quality is not quite as good as the main output but will be good for late night listening. 1080p menu system is a nice upgrade. Some complain that it is not 4k, but who needs it? My old remote works well (since it is the same model). Responds quickly to commands. Quick menu is nice and works well. Sirius XM works thru the required HEOS app on my phone. Some other streams work natively. I have not been able to connect to my Windows Home Server for my music library yet. Included all OEM accessories and a link to the manual, which is linked in the system menu. Other than a few finger smudges on the face, it looks good. As a refurb, I bought the extended warranty just in case.
