Design outcomes

Primary

MeasureTime frame
To evaluate the incidence, types, and severity of adverse events (AEs) occurring during static magnetic field stimulation.

Secondary

MeasureTime frame
This study investigates the effects of static magnetic field stimulation on hot flush symptoms and sleep-related indicators, confirming the presence or absence of physiological changes due to sympathetic inhibition.
