Electromagnetic field therapy has been reported to be beneficial in patients with multiple sclerosis (MS) with significant fatigue. This study was designed to evaluate the long-term effects of Bio-Electro-Magnetic-Energy-Regulation (BEMER) on MS-related fatigue.
This was a monocenter, patient- and rater-blinded, placebo-controlled trial.
There were 37 relapsing-remitting patients with MS with significant fatigue in the study.
The intervention consisted of BEMER magnetic field treatment for 8 minutes twice daily in comparison to placebo for 12 weeks.
The primary outcome criterion was change in the Modified Fatigue Impact Scale (MFIS) between baseline and 12 weeks. The secondary outcome criteria were changes of the Fatigue Severity Scale (FSS), a general depression scale-long version (ADS-L), Multiple Sclerosis Functional Scale (MSFC), and the Expanded Disability Status Scale (EDSS).
There was evidence of a significant difference of MFIS value (primary outcome criterion) after 12 weeks in favor of the verum group (26.84 versus 36.67; p = 0.024). In addition, FSS values were significantly lower in the verum group after 12 weeks (3.5 versus 4.7; p = 0.016). After 6 weeks' follow-up, verum and placebo groups did not differ in experienced fatigue (MFIS, FSS). Regarding the subscales of the MFIS, there was a significant decrease in physical (p = 0.018) and cognitive (p = 0.041), but not in psychologic subscales only in the verum group regarding the timepoints baseline and 12 weeks. BEMER therapy was well tolerated.
In this pilot study, we were able to demonstrate a beneficial effect of BEMER intervention on MS fatigue. As this was only a pilot study, trials with more patients and longer duration are mandatory to describe long-term effects.
