The Disk Doctor WG30 G2 is not just a simple back brace. It is a lumbar spine fixation medical device that has obtained approval from the Korean Ministry of Food and Drug Safety and is equipped with clinical evaluation data and notarized translated documents.

On this page, based on official clinical evaluation data, we provide information on the clinical evidence supporting the WG30 G2 as a medical device and who it is suitable for.


What kind of product is the WG30 G2?

The WG30 G2 is a lumbar stabilizer that wraps around the waist with a belt-type air column and provides support and fixation by inflating the product with air.

Through this principle, the lumbar region can be effectively stabilized, and it is possible to fix or support the bone during fracture fixation by holding it in place. It is also used for lumbar stabilization to aid in the healing of the wound.

The user can manually adjust the compression intensity using an air inflation method, making it suitable for both home use and wearing while out and about. It is designed to be ready to use immediately simply by reading the instruction manual, without the need for separate training.



Who is this product suitable for?

The product's applicable targets specified in the WG30 G2 clinical evaluation data are as follows:.

It is applied to stabilize and support bones in the event of back injuries or fractures, acts as a rehabilitation aid by relieving pressure from the patient's own body weight, and can improve the effectiveness and duration of hospital treatment or recovery.

Specifically, the following individuals are eligible: those with acute or chronic lower back pain; those diagnosed with a herniated disc (wearing after consultation with a specialist is recommended); those recovering from a lumbar fracture; those requiring lumbar stabilization to supplement hospital treatment; and those needing an assistive device during rehabilitation.



What is the operating principle of WG30 G2?

The WG30 G2 features a belt-type air column that wraps around the waist and inflates the product with air. The air pressure evenly supports the lumbar region, distributing the load on the spine and stably restricting movement to aid in pain relief and recovery.

As confirmed in a clinical study by the Department of Orthopedics at Seoul Paik Hospital, Inje University College of Medicine, X-rays confirmed that the gap between the 4th and 5th lumbar vertebrae was stretched (expanded) by an average of 2 mm when worn, and it was reported to have the effect of reducing intradiscal pressure by approximately 251 TP3 T.



What are the differences compared to similar medical devices?

According to the comparison table of homologous medical devices included in the clinical evaluation data, the following differences exist when comparing the mechanism of action of WG30 G2 and similar products.

Conventional lumbar stabilizers are designed with an inverse C-shape to match the body's normal 'S' curve, ensuring a snug fit against the spine in accordance with its natural curve. The WG30 G2, however, utilizes a belt-type air column that wraps around the waist and inflates it with air to provide support and fixation. It employs the VAP™ (Vertical Air Pressure Technology) principle, where air pressure supports the spine in the vertical direction.

Sizes are available in a variety of 6 options: S, M, L, XL, 2XL, and 3XL, allowing you to choose the size that fits your body type.

Furthermore, a search of CFDA data revealed no records of defects involving similar products, and the safety of our product has been confirmed in the same manner.



Things to check before wearing

WG30 G2 is a medical device. For safe use, please be sure to check the precautions specified in the clinical evaluation data.

Those who require caution before use Patients with severe hypertension, heart disease, cerebrovascular disease, or hyperhidrosis must consult a doctor before use. Pregnant women are prohibited from using this product. Patients with herniated discs must consult a specialist before wearing it.

Precautions during use The air pressure must never exceed 14 PSI. It is most effective when worn directly on the skin, but those with sensitive skin may wear it over a thin cotton undergarment. If any adverse effects occur, stop use immediately and consult a doctor. Shared use by multiple people is prohibited due to the risk of secondary infection. Keep out of reach of infants and young children.

Wearing checks Before wearing, please visually inspect the product for any damage or defects. You must check for any residual air inside the belt before use. If there is residual air, turn the air valve screw counterclockwise to release all remaining air, then turn the screw clockwise to tighten it to complete the preparation for wearing.



Official certifications of the WG30 G2

WG30 G2 is qualified as a medical device with the following official documents.

We have obtained the Korean Ministry of Food and Drug Safety's medical device approval (No. 17-962) and possess clinical evaluation data for lumbar spine fixation devices (in Korean and Chinese). We have completed the translation and notarization of the clinical evaluation data at the Gongjungin Shinmunsik Office (Registration No. 4198 of 2017) and also possess a comparative table of medical devices of the same type (based on CFDA data).



How are the Disk Doctor WG30 G2 and WG50 G2 different?

Both products are inflatable lumbar spine fixation medical devices, but they differ in their support methods and structures.

The WG30 G2 features a single-belt structure, making it suitable for daily lumbar support and the management of early to mid-stage lower back pain. It is ideal for those starting to use a brace for the first time, those seeking relatively light lumbar support, and those who require a comfortable fit during activities.

The WG50 G2 features a double-belt structure, making it suitable for patients with severe disc problems, stenosis, or chronic lower back pain who require strong immobilization. It is recommended for those who have found physical therapy ineffective, those experiencing radiating pain (leg numbness), and those who need to wear it for extended periods.
