Impulse Magnetic-Field Therapy for Insomnia (Landmark Study)
Grade A-Randomized, double-blind, placebo-controlled trial2001
What did this study find?
Researchers randomly assigned 101 adults with insomnia to impulse magnetic-field therapy or a placebo device for four weeks. Ninety-four percent of the treated group reported some degree of improvement, and every efficacy measure the investigators tracked improved significantly against placebo. The published report does not describe the full signal parameters of the field used.

A positive PEMF study is not evidence for a specific device unless the signal parameters studied, frequency, intensity, waveform, and exposure duration, are reasonably comparable to what that device produces. Where this record does not list those parameters, the source report did not publish them. See the grading methodology. Library last reviewed 2026-08-27.
