In 2001, Pelka, Jaenicke, and Gruenwald did a double-blind study, treating patients who suffered from insomnia with PEMF therapy.
70% of them reported that their insomnia was completely gone, 24% of them experienced major improvement, and the remaining 6% said they experienced a small but significant improvement.
In other words, 9 out of 10 patients who suffered from insomnia said that they experienced major improvement or that their insomnia had completely ceased as a result of receiving PEMF therapy.
