Abstract
Background: Electromagnetic-field therapy has beneficial short-term effects in multiple sclerosis (MS) patients with major fatigue, but long-term data are lacking. PRIMARY STUDY OBJECTIVES: To evaluate the long-term effects of a specific electromagnetic therapy device (Bio-Electromagnetic- Energy-Regulation ) on MS-related fatigue, we designed a crossover control of a previously performed randomized controlled trial and a long-term open-label follow-up trial.

Design and setting: Crossover and open-label follow-up trials at a single neurological outpatient center.

Participants: Patients with relapsing-remitting MS who had major fatigue (N = 37 patients).

Intervention: After a previous randomized controlled trial (exposure to low-frequency pulsed magnetic fields for 8 min twice daily or to placebo treatment for 12 wk), a crossover from control to treatment for another 12 weeks, followed by an open label follow-up trial to 3 years, were done.

Primary outcome measures: The outcome criteria were the Modified Fatigue Impact Scale (MFIS), Fatigue Severity Scale (FSS), German long version of the Center for Epidemiologic Studies Depression Scale (CES-D), Multiple Sclerosis Functional Scale (MSFC), and Expanded Disability Status Scale (EDSS).

Results: Patients previously on placebo during the randomized controlled trial experienced significant reductions in fatigue after crossing over to treatment. The MFIS and FSS scores were significantly lower in the open-label group than in the control subjects after follow-up. Participation in the open-label treatment was the strongest predictor of low fatigue outcome after follow-up. Electromagnetic-field therapy was well tolerated.

Conclusions: In this long-term study, a beneficial effect of long-term BEMER therapy on MS fatigue was demonstrated. Electromagnetic-field therapy may be a useful therapeutic modality in MS patients with severe fatigue.
