Adding low-field magnetic stimulation to noninvasive electromagnetic neuromodulatory therapies

摘要

Driven by the limitations of traditional approaches to treating depression, there has recently been a surge of studies examining the utility of various noninvasive neuromodulation technologies in the treatment of depression. In this issue, Rohan et al. (1) report substantial improvement in mood immediately following one 20-minute treatment application of low-field magnetic stimulation (LFMS), performed with a novel portable tabletop device Figure 1. The stimulation paradigm they utilized consists of a 1-kHz oscillating magnetic field, adapted from the component of the magnetic resonance imaging protocol that they previously serendipitously found to have beneficial mood effects (2).
