This animal study examined whether 50 Hz ELF-EMF exposure at two intensities (1 mT vs 7 mT) alters hippocampal gene transcripts related to neuroplasticity and cell survival in adult rats across repeated exposure cycles. The authors report intensity- and exposure-number-dependent modulation of mRNA expression, with 1…

This animal study exposed 40 adult male rats to a 10 Hz (4 mT) extremely low-frequency electromagnetic field for 1 hour daily for either 7 or 30 days. The authors report improved spatial memory after prolonged (30-day) exposure, alongside increased hippocampal BDNF levels. They also note a significant body weight…

Jan 1, 2022
This pilot randomized, sham-controlled, double-blind trial evaluated extremely low frequency, low-intensity ENTF electromagnetic field therapy in subacute ischemic stroke patients with impaired upper extremity function. The per-protocol results reported greater improvements in motor function and disability outcomes…

Jan 1, 2020
This study evaluated whether adding extremely low frequency electromagnetic field (ELF-EMF) exposure to a rehabilitation program affects apoptosis-related gene expression in post-stroke patients. Forty-eight patients (3–4 weeks post-incident) were divided into ELF-EMF and non-ELF-EMF groups, with the ELF-EMF group…

Jan 1, 2017
This study assessed whether adding extremely low-frequency electromagnetic field (ELF-EMF) exposure to a 4-week poststroke rehabilitation program affects nitric oxide (NO)-related biomarkers and patient status. Forty-eight poststroke patients were assigned to ELF-EMF versus non-ELF-EMF rehabilitation, with the…
