For those who want to consistently manage their waist in their daily lives
What is the difference between a standard back brace and the WG30 G2?
Standard back braces are designed to wrap around the waist using a simple compression method.
You feel a sense of support when wearing it initially, but the pressure is distributed when worn for a long time.
There are many cases where support is not maintained.
Unlike this, the Disk Doctor WG30 G2
This model is designed with both a lightweight and comfortable fit and an air pressure support structure in mind.
① Single belt structure
The WG30 G2 is designed with a single belt structure.
It is characterized by being easy to wear and having minimal burden.
Gently wrapping around the waist
It is designed to be worn naturally during daily life.
② Hand pump air inflation method
If you inflate it using a hand pump
Air pressure gently supports the lower back and provides support.
Not a strong tightening compression method
In a way that provides comfortable support
It is characterized by minimal discomfort even when worn for a long time.
Also tailored to individual body type and condition
You can directly adjust the pressure, allowing for a comfortable fit.

FAQ (WG30 G2)
Q1. What is the biggest difference between the WG30 G2 and the WG50 G2?
The belt structure and support capacity are different.
The WG30 G2 features a single belt design, making it lightweight and highly mobile, and is suitable for environments with a lot of daily movement.
The WG50 G2 uses a double belt system with a higher belt height, and,
It is characterized by a traction force that lifts the lumbar spine more strongly from above and below.
For those who simply want to start lightly or desire a product with minimal wearing burden, the WG30 G2,
We recommend the WG50 G2 for those with pronounced back symptoms or who require stronger support.
Q2. How do I select the size?
It is most accurate to measure your navel circumference directly with a tape measure rather than your pants size.
You must wear the correct size for the air column to properly support the waist and for the traction effect to be fully exerted.
If your measurements fall on the size boundary, please choose one size larger if you have a protruding belly, or your regular size if you have a slim build.
Q3. How long should I wear it per day?
Generally, 5 to 9 hours a day is recommended, but it is fine to wear it frequently if back support is needed.
In a clinical study at Inje University, the wearer's 74.7% was worn for more than 12 hours a day, and,
It has been confirmed through research that there is no significant disruption to daily life.
You can adjust it to suit your lifestyle.
Q4. Won't wearing it for a long time weaken the back muscles?
You do not need to worry. Standard compression braces constrict the waist by replacing muscle power, so there is a risk of muscle weakening with long-term use.
On the other hand, the Disc Doctor uses air pressure to vertically traction between the vertebrae, so it does not compress the muscles.
Results of isokinetic exercise evaluation (Cybex 6000) after wearing in the 1st clinical study at Inje University
It was confirmed that the strength of the lumbar extensor muscles (muscles that straighten the lower back) is actually maintained for a longer period.
The research team evaluated that this helps strengthen muscles.
Q5. Is it effective if used like a regular belly band without inflating it?
The traction effect occurs when air pressure is injected.
The results confirmed in the clinical study at Inje University, including an average 2mm extension of the L4-L5 intervertebral space and a reduction in disc pressure of approximately 25%, were all observed when air was injected.
If you do not inflate it at all, you can only expect support equivalent to a standard belly band, so we recommend inflating it with at least a minimum amount of air to form a column before use.
Q6. Is it okay to wear this while driving?
Yes, it is wearable. However, if you frequently drive for long periods, the WG50 G2, which provides stronger support, or the WD57P, which includes a hard panel, may offer greater satisfaction.
A clinical study at Inje University also confirmed a tendency for the pain reduction effect to be greater the longer the wearing time and the older the age.
Q7. Has the product's effectiveness been verified through clinical studies?
Yes. Two official clinical studies were conducted at the Department of Orthopedic Surgery, Seoul Paik Hospital, Inje University College of Medicine, and,
Its effectiveness has been proven through objective data utilizing radiographic examinations and isokinetic motion measurement devices.
