Nighttime bedwetting, also called nocturnal enuresis, can cause family problems and embarrassment to the person suffering with it. Obviously all of us start out life as a bedwetter, but most develop nighttime control at around 5 or 6 years of age. The causes of enuresis are variable, with some cases being the result of obstructive sleep apnea (OSA). Treating the OSA improves the nocturnal enuresis.
This study evaluated the effect of magnetic stimulation on nocturnal enuresis. Researchers put the magnet over the subjects lower back, just above the tailbone. The magnet was turned off and on rapidly 5 times per week. The results showed significant reduction in nocturnal enuresis frequency. Sham magnetic stimulation also showed a reduction in nocturnal enuresis frequency that was almost as large as the real magnetic stimulation. However, the frequency of enuresis returned to baseline after the sham magnetic therapy was stopped. In the real magnetic stimulation group the effect persisted a month after therapy was stopped.
