Extensive laboratory testing has shown that it's not the magnetic field strength, but the field gradient (steepness of the slope of the magnetic field) that is the determining factor in alleviating pain. This unique steep field gradient generated by the Quadrapolar array is what blocks the pain signal.

This is why the QuadraBloc™ Science is so effective when placed over the irritated nerve.

Over a decade of cell research was done at Vanderbilt University Medical Center in Nashville Tennessee and clinical data was collected at various Medical Centers and Universities around the world.

I had severe tennis elbow and couldn't get pain relief. I put a Quadrabloc on my forearm and the pain was gone within 10 minutes. I continued to wear the Quadrabloc for 24 hours and the pain has not returned I have Plantar Fascitis on the bottom of my foot. I put a Quadrabloc at the front of my heel every night and it is continuing to improve

I have constant neck and shoulder pain from stress. When I leave the blocs in the right places I experience great relief. I also shared them with my future mother in law. She used one to get rid of a head ache. Very impressive

Seven years ago I sustained a ruptured lumbar disc and could hardly walk because of the pain. I had used a set of MagnaBlocs at that time which decreased the pain so I could walk and helped me heal. Recently, I revisited that injury, found the partial set of MagnaBlocs which helped but wondered where I could find the manufacturer to add the missing one. I found QuadraBlocs, the new improved version and got one. It is so much stronger and works even better. A "simple" task like standing at the sink to wash dishes without burning pain going down my leg is relief. I had been waiting for the fall season to plant my 350+ potted roses bushes which I brought to my new home. The lumbar disc injury reappeared right when the weather was perfect for planting. Four days after I started using QuadraBloc, I was on my knees planting and able to get up and down without pain.

within 5minutes of applying Magna blocs my back pain was relieved. I wore everyday x 3 weeks and was able to discontinue most pain medication to treat my post-op pain. i use them periodically to treat chronic back pain related to spine surgery. They continue to provide relief

Qudrabloc is the name of an amazing device. It's like magic. The president of our company was suffered from a continous pain and due to old age, he can't have surgery. Therefore, quadrabloc was the solution. it helped him to get rid of pain and limp.

Once again Magna Bloc came to the rescue. As an Amway distributor had ordered several style. Was very disappointed to see that there was no longer an association. I have had great success with the magnets, have sold them and just today had a customer tell me how great it was to reduce back pain. 8/26/09- fell, foot was in a lot of pain-8/27 saw Dr.-he said I had damaged my tendon. He wrapped it and said I had to be very careful because this is serious. If I had any pain to call him. 2 days later had pain, called him-no return call. Figured out a plan-took the shoe magents-one under my foot and wrapped the other one around my ankle, wrapped it with ace bandage to keep in place-then for good luck, turned a brace for the wrist upside down-wrapped it around my ankle- to keep everything in place- put a sock over it and have not had any pain at all. I love magna bloc

Our family has experienced pain relief for many years from the magnabloc magnets:sinus pain, migraine, dental pain, back strain and injury, muscle soreness, and even swelling is relieved with this wonderful device. And, I'll have you know, they endure years of abuse such as being left magnetized to the inside of our dryer! The casing was distorted but the magnet still works great! We're ordering another set...Thanks for sticking with your findings and delivering a wonderful healing product to those of us who would rather heal than be medicated.

A lady I know was involved in a car crash injuring her shoulder. I placed three magnablocs on her spine.Ten minutes later she raised her hand and scratched her head. Then she realized she had not been able to do for the past five months!

I previously owned Magnabloc universal pad with 5 magnet groups .The pad worked excellent for years . Today i recieved one new Quadrabloc single magnet .I tested immediately and as before ,pain is GONE in minutes and hours after removing , pain still reduced . I first tried wrist bands at an Amway sales meeting . One worked in 5 minutes and pain reduced for nearly 2 hours ; pain AND swelling/inflammation . My wrist was so inflamed I couldnt move it due to stiffness as well as pain . 5 minutes and all symptoms were gone . GREAT product i certainly recommend.

I've got hemorrhoids for about one month. I've tried one QB and it helped, the pain decreased. Thanks.

I've given one QB to my friend's son, who is 12 years old and he has got Spastic Hemiplegia due to an injury during birth. This type of disease is currently untreatable. His right hands flexors are contracted all the time. They tried out several treatments from accupuncture to orthesis but nothing helped. After a few weeks of using QB (on the C7 vertebrae) he and his parents noticed that when he doesn't pay attention to his hand, the contraction disappear, his right wrist and fingers become relaxed, and his forearm is nearly totally straighten out. They also noticed about 40% increase in an exercise, where the boy have to hold a ball and let it fall when his parents tell him (e.g. without magnets he can do it about 10 times, with the magnet 14). Before using magnets, these improvements (relaxation) only appeared when he had fallen asleep. Altough this development is great, in an uncureable disease, I hope there will be more by the time.

I use quadrabloc to treat mononeuropathia - complex regional pain syndrome type II (causalgia). It helps!

An amazing device. I didn't believed in this, but you don't have to. I strained my left hand during flat renovation, and nothing helped..except this. I borrowed it to my friends, and they got the same results..pain relief.. Thank you QB!

I have been using four Quadrablocs for the past month. I've had fibromialgia for twenty years in my entire back, neck and ribs. I take pain medication three times a day and two muscle relaxers. Now with the help from your magnets, I only take ONE PAIN PILL in the morning! About 2 pm my pain is very bad again, so I put the magnets just a little above the worst pain points. In five to ten minutes I have no pain at all, and am more alert and less irritable. I wear them until bedtime, and find that my muscles feel more relaxed so I can go to sleep without taking any sleeping pills, pain pills, or anything else. I have tried so many different things to help with my pain and this has worked the best by far. I feel very lucky to have found this method. I think it is healthier for me, because I don't have to take so many medications. It is a natural alternative for pain relief.

Our Magnablocs get more use than any other pain reliever, because it works! The money we have saved on Aspirin alone has more than paid for the discs! Thanks you, thank you, thank you!

I only wish I had known about Magna Bloc™ 11 months ago, before I started on that long, long journey which has included four major surgical operations, four injections into my knee, four injections of steroids into my back, plus multiple visits to different physicians… Although all have been kind and caring, I'll summarize things by saying that Medicare has lost a lot of money on me during the past 11 months!

The first night after I received [Magna Blocs™] was the first time in about three months I had slept through the night. I even got to go out with my friends in Cancun and do what normal teenagers do. Yet, believe it or not, I was still able to get out of bed the next morning!

Within minutes after application of six magnets, [my mother] was unable to feel her pain and was able to take a 'walk' in the neighborhood… Now, eight months later she is still living a very active life for an 80-year old great grandmother…The quality of life she now enjoys is amazing- certainly a far cry from the person who could not leave her recliner!

Exactly 11 months after I left the golf course, I went out to the golf shop, borrowed a putter and four balls and went out to the putting green and putted for 25 minutes… My success on the longer putts was almost as good as 11 months ago… I plan to start a little chipping and more arm and shoulder exercises and if you think it is okay I'll even start swinging some of the other clubs!

What the Magna Blocs™ accomplished is, to me, nothing short of miraculous. I now can sleep through the night… I now can walk freely without a limp.

During the past year and three months, my physician has used everything available to bring me relief… The Magna Blocs™ were applied in the morning before noon. By mid afternoon I was feeling some relief and by bedtime I was more comfortable. Amazingly, the next morning I was pain free and have remained so to date!

Within just a few short minutes the pain in my wrists and hips was improved and over the next few weeks my pain had actually become tolerable… Magna Bloc™ therapy is helping me return to better health and my optimism for an acceptable, if not complete, recovery has never been higher!
