McKenzie’s exercises are renowned for addressing and preventing neck and back issues. Duo Curve exercises follow these principles but can be performed more easily and deeply in a lying position, thanks to gravity and expansion of airbags.

Tractioning the neck or stretching the spine with a bent back and rounded shoulders is ineffective. First, you need to straighten your back and open your shoulders to achieve real traction and curve correction effects.

DUO CURVE™ accomplishes this by simultaneously addressing both neck and back curvatures.

We’ve undergone numerous design changes and performance tests with patients in our clinics. And they felt the actual benefits of using Duo Curve, including:

Effectiveness of traction and curve enhancement
Improving oxygen supply to the chest
Facilitating smoother breathing

In just 10 minutes, the Duo Curve helps restore normal curvatures of the neck and back, correcting improper postures such as forward head posture, hunchback and round back. It also effectively relieves upper shoulder and back pain.

These effects are achieved because the Duo Curve simultaneously stretches your neck and back.

Many, including my patients, endure persistent discomfort and pain in the chest, neck, and back areas, which often remains unresolved.

For this reason, I felt compelled to take action as a spine doctor to assist individuals grappling with persistent and recurring pain.

It motivated me to invent the Duo Curve, a device for simultaneous traction and curve restoration.

Realign abnormal body posture: Elevate your back to correct posture.
Stretching Effect: As your back is raised, your chest stretches out, both shoulders naturally fall downward, and you may feel the shoulder blades gathering.

Core Design: The DUO CURVE™ features a separation hinge mechanism.
Functionality: This mechanism effectively separates the neck from the back while maintaining the C-Shape, guiding the correct direction of neck traction.

Back Straightening and Chest Opening: As the back straightens and the chest opens up, the lungs naturally expand.
Improved Lung Function: This can normalize lung function, facilitating better breathing by reducing compression from poor posture or hunchback.

In 2017, I shared a sketch with my old friend in South Korea, and since then, we have dedicated 7 years to developing DUO CURVE. From wooden mock-ups to elastomer molds and finally to sample molds, we spent years testing, adjusting, and iterating until achieving the perfect implementation. We take pride in the meticulous quality of Duo Curve.

Best Combination of elastomer materials for hardness that match the viscoelasticity of human skin and bones. You can feel both comfort and acupressure.

The structure of the double layer airbags(Patent Pending) is not the same as the single layer airbag. It widens the range of motion and maintains balance and allows to lift more weight.

Airbags that tow the neck and straighten the back are connected to each air pump. Therefore, the device can be used within the range suitable for your body shape by adjusting the amount of air injection.

DUO CURVE™ is suitable for anyone regardless of body size. That’s because everyone’s neck and back are almost the same even though their bodies are different in size.

For those who spend long hours at their desks looking at computers, frequently bow their heads throughout the workday, use smartphones—which can contribute to muscle tension in their neck and spine—or often experience muscle tension from exercise.
