Temporal analysis of remote electric neuromodulation for the prevention of migraine
This Short Communication, which has been recently published in our partner journal Pain Management, evaluates the onset, magnitude and persistence of efficacy of remote electrical neuromodulation compared with placebo for the preventive treatment of migraine.
Abstract
Aim: To evaluate the onset, magnitude and persistence of efficacy of remote electrical neuromodulation (REN) compared with placebo for the preventive treatment of migraine. Materials & methods: Analysis was conducted on data from a prospective, double-blind, placebo-controlled clinical trial, which assessed the efficacy of REN for the prevention of migraine. The number of monthly migraine days (MMD) per group was calculated in 2-week intervals and compared between the groups. Results: Differences between the active (N = 95) and placebo (N = 84) groups reached significance at 2 weeks: therapeutic gain 0.84 MMD, p = 0.036. Four weeks gain 1.59 MMD; p = 0.025, 6 weeks gain 2.27 MMD; p < 0.001, 8 weeks gain 2.68 MMD; p < 0.001. Conclusion: REN provides rapid and consistent efficacy in preventive treatment of migraine.
