Feb 26, 2026
This randomized, between-subjects study in 98 healthy volunteers tested whether patterned EMF stimulation alters Digit Span performance and EEG activity. Theta-Burst stimulation reduced working memory (Digit Span Backward) and was associated with increased high-alpha activity in frontal regions. Theta-Gamma…

Jan 1, 2025
This triple-blind randomized study tested whether 26.5 minutes of 26 GHz (5G) RF exposure at environmental-like levels alters salivary stress biomarkers in healthy adults. Salivary cortisol and alpha-amylase measured before, during, and after exposure did not differ between real and sham conditions. An exploratory…

Jan 1, 2025
This randomized, double-blind, sham-controlled study tested whether CACNA1C rs7304986 genotype modifies sleep EEG responses to 5G RF-EMF exposure. The authors report a genotype-by-exposure interaction, with 3.6 GHz exposure in T/C carriers associated with a faster NREM sleep spindle center frequency versus sham. The…
Effects of radiofrequency electromagnetic fields on cognitive function in elderly subjects (60+ years)-Results of an experimental randomized sham controlled double-blind cross-over study in women and in men.

Jan 1, 2025
This double-blind randomized sham-controlled cross-over study tested short-term RF-EMF exposure effects on cognitive performance in 60 healthy adults aged 60–80 years. Participants completed attentional tasks during exposure to GSM 900 MHz, TETRA 385 MHz, or sham across nine sessions. Two of 16 outcomes showed…

Jan 1, 2023
This paper presents the protocol for the EMAGINE multicenter, double-blind, randomized, sham-controlled trial testing an extremely low-frequency, low-intensity, frequency-tuned electromagnetic field therapy (ENTF) after subacute ischemic stroke. Participants will start active or sham treatment 4–21 days post-stroke,…

This double-blind randomized sham-controlled repeated-measures study examined short-term 50 Hz ELF-EMF exposure (28 μT) to the chest and its effects on HR and HRV in 34 healthy young men. HR deceleration occurred in both EMF and sham conditions, but several HRV indices (SDNN, RMSSD, LF, HF) increased only in the EMF…
Impact of low-level electromagnetic fields on the inducibility of atrial fibrillation in the electrophysiology laboratory.

Jan 1, 2021
This randomized sham-controlled study tested low-level electromagnetic field stimulation (3.2 × 10 G at 0.89 Hz) applied around the head in patients undergoing ablation for paroxysmal atrial fibrillation. Eighteen patients completed the protocol, and LL-EMF was associated with shorter pacing-induced AF episodes after…

Jan 1, 2016
This pilot randomized study evaluated systemic extremely low-frequency magnetic field (ELF-MF) therapy versus sham in 37 women with fibromyalgia using a crossover sequence. The abstract reports significant short-term reductions in pain and improvements in fibromyalgia-related symptom and function questionnaires…
Pulsed electromagnetic field treatment enhances healing callus biomechanical properties in an animal model of osteoporotic fracture

Jan 1, 2014
This animal study evaluated whether daily pulsed electromagnetic field (PEMF) treatments improve delayed fracture healing in skeletally mature ovariectomized (OVX) rats. By 6 weeks, PEMF-treated rats showed improved hard callus elastic modulus and radiographic evidence of better callus bridging compared with sham…
