NCT00901862

Brief Summary

Background: The therapy with pulsed electromagnetic fields (PEFs) has been used as a therapeutic modality for at least 40 years. However, their effect in the migraine prophylaxis is unclear. Objectives: Evaluate the prophylactic effectiveness of the therapy with PEFs in the handling of migraines. Methodology: Placebo-controlled, randomized, double-blind, crossed clinical study.

Outcome Measures

Primary Outcomes (1)

  • The primary outcome measure was change from baseline in the number and peak severity of migraine attacks during each double-blind phase

    3 months

Secondary Outcomes (1)

  • The secondary outcome was the proportion of patients who responded to each treatment with at least a 50% reduction in migraine attacks relative to baseline

    6 months

Study Arms (2)

1 Active PEFs

ACTIVE COMPARATOR

The pulsed electromagnetic fields were directed to the wrist. The model used has the form of a bracelet called Quantum MH-2MR which uses, as a source of power, an alkaline battery of 1.5 volts connected to an electronic circuit formed by two hybrid circuits of magnetic oscillation and a control system of all the generating frequency system.

Device: Pulsed magnetic fields (Quantum MH-2MR bracelet)

2 Sham

SHAM COMPARATOR

The sham machines were identical to the machines in actual operation in both phases of the study. The only difference was that the hybrid circuits crucial for the generation of the electromagnetic field had been removed.

Device: Sham pulsed magnetic fields (Quantum MH-2MR bracelet)
