What did this study find?
Two hundred twenty-five patients with painful diabetic peripheral neuropathy were randomized to pulsed electromagnetic field treatment or sham. The study failed its primary endpoint: pain reduction in the treated group was not significantly greater than in the sham group. This is the largest negative neuropathy trial in the library and is reported here unmodified.

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.
