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.

David Buck: A Life Without Limits

January 5, 1993 began as a very typical day for David Buck.  David, an extreme skier, was once again above the tree line at the top of Mount Baldy at an altitude greater than 9,000 feet and staring down the familiar path that would take him to the bottom.  For David, this is his normal. He finds peace in attacking life with a bold, self-confident belief that he manages to wrap in a gentle spirit characterized by a warm, engaging smile. Near immediately after beginning his trek down the mountain, David noticed a young man on a snow board traveling down the mountain behind him.  David understood...
