What is Quadrabloc?

Quadrabloc is a wearable neuromagnetic device for the management of muscular aches and pains associated with activity, aging, or following surgery. 

Quadrabloc can be worn as a disc placed directly on the site of pain or as a garment.  Quadrabloc discs help manage localized pain in a specific area of the body such as the elbow, head, or wrist.  The garments are appropriate to address pain in larger regions on the body such as the lower back, shoulder and knee. 

Quadrabloc is safe, non-addictive, reusable, and does not require charging.  And, Quadrabloc comes with a 30-day, 100% purchase price money back guarantee.

How Does It Work?

Quadrabloc works to relieve pain using patented, quadrapolar magnetic discs to block the pain signals that originate in the sensory nerve fibers. These fibers, located throughout the body, are responsible for sending pain signals to the brain. 

By placing Quadrabloc directly over the site of pain, Quadrabloc interrupts the pain signals and relieves pain. Pain relief can be achieved in a matter of minutes with proper placement of a Quadrabloc disc or garment.

Quadrabloc was originally developed in the Department of Neurology at Vanderbilt University School of Medicine.

Frequently Asked Questions

What kinds of pain can Quadrabloc products relieve?

Quadrabloc products may be used to relieve any common pain discomfort associated with aging and activities of daily living. Many people use them on the back, hip, knee, shoulder, ankle, elbow, head and wrist. Quadrabloc is not intended to treat diseases and underlying medical conditions.

How quickly does Quadrabloc work?

Laboratory tests demonstrate that Quadrabloc works in as little as four minutes. However, for some people it may take longer. If you do not begin to feel relief in 5–10 minutes, you should move the Quadrabloc product slightly to better target the site of pain.

Are the products guaranteed?

Quadrabloc products are covered by the 100% Satisfaction Guarantee. In addition, Quadrabloc products are warranted against defects.

What is the life expectancy of Quadrabloc products?

With proper care, the discs will last a lifetime. The life expectancy of other Quadrabloc products depends on how frequently the product is worn and washed. They can last many years.

Does Quadrabloc stop all sensation?

No. Quadrabloc magnets work on a specific nerve pathway and will not interrupt all sensation. Your skin will not feel numb and if you bump yourself while wearing Quadrabloc products, you will feel it.

Are there any side effects?

Other than occasional, minor skin irritation, no side effects have been reported with the proper use of Quadrabloc. It is important to understand that Quadrabloc products use magnetic technology. They must not be used near sensitive medical equipment or implants such as pacemakers, implanted defibrillators, aneurysm clips, infusion pumps, or implanted neurostimulator devices.

I have a TENS device. Is QuadraBloc the same as TENS?

Transcutaneous electric nerve stimulation devices, TENS devices, stimulate low threshold peripheral nerves that transmit position and touch signals. When stimulated these nerves are thought to work as a counter stimulus to pain. You have seen the same mechanism of action, in reflex action, when you hit your funny bone at the elbow. What do we all do reflexively? We rub the skin over the elbow vigorously. QuadraBloc devices block the pain signal at the cell membrane level. In doing so, the pain signal is not propagated and sent to the brain where perceived as pain. This mechanism of action...

Consider this, we know more about how the QuadraBloc works to block pain than we know how Tylenol works. Watch This Video... .embed-container...

How did you learn about QuadraBloc Dr. Brad?

Questions on QuadraBloc with Dr. Brad Question: How did you learn about QuadraBloc? In 1988, I was introduced to the predecessor to QuadraBloc by one of my patients.

He insisted that I come to his office to meet the inventor and see for myself. When I arrived at the patient’s office, I witnessed several older gentlemen moving about like they were warming up for an athletic event. They also had these checker sized discs taped to specific locations where they...
