The type of magnet used is this study is not a Q magnet.
The safety and effectiveness of Q magnets has not been established in the treatment of erosive gastritis.
Every week, new research is published strengthening the claim that static magnets can be optimised for therapeutic effects. While the magnetic device used in this study is not a Q magnet, the multipolar arrangement does exhibit similar properties.
Researchers at Semmelweis University (Budapest) conducted a randomised, double blind placebo-controlled trial to investigate the effects of a multipolar static magnet device on symptoms related to erosive gastritis. The same magnetic array has previously been shown to have an analgesic effect on mice and increased the pain threshold in humans (see references below).
