Extremely Low-Frequency Electromagnetic Stimulation (ELF-EMS) Improves Neurological Outcome and Reduces Microglial Reactivity in a Rodent Model of Global Transient Stroke.
This animal and laboratory study evaluated extremely low-frequency electromagnetic stimulation (ELF-EMS) in a rodent ischemia-reperfusion stroke model and related in vitro/slice experiments. The authors report improved neurological and behavioral outcomes, increased neuronal survival, and reduced glial/microglial reactivity with 13.5 mT/60 Hz exposure. They also report reduced induced microglial migration in cell assays and modulation of inflammation-related markers in hippocampal slices.
Key points
- The study tested ELF-EMS at 13.5 mT and 60 Hz in a rodent global transient stroke (ischemia-reperfusion) model.
- ELF-EMS was reported to improve neurological score and behavior after ischemia-reperfusion injury.
- Hippocampal neuronal survival was reported to increase and glial reactivity to decrease with ELF-EMS.
- Microglia were described as showing early signs of treatment effect relative to other glial responses.
- In vitro ELF-EMS decreased LPS- and ATP-induced microglial migration in scratch and transwell assays.
- In organotypic hippocampal slices, ELF-EMS was associated with reduced microglial reactivity and improved neuronal survival.
- The authors state this is the first report of an EMF treatment directly impacting microglial migration.
