Electromagnetic field stimulation modulates working memory and cortical alpha oscillations in healthy adults

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…

Neuromodulation With Electromagnetic Field Stimulation via Gamma Oscillations Improved Mini-Mental State Examination Scores in Patients With Cognitive Impairment.

This pilot clinical trial evaluated a portable helmet system delivering electromagnetic field stimulation at gamma oscillation frequencies (70100 Hz) in patients with cognitive impairment. Sixteen patients were included, with ten receiving stimulation after protocol refinement. MMSE scores increased on average from…

The effect of inter-electrode distance on the electric field distribution during transcutaneous lumbar spinal cord direct current stimulation.

This engineering-focused study examined how inter-electrode distance in transcutaneous spinal direct current stimulation (tsDCS) affects electric field distribution in the lumbar and sacral spinal cord. Peak E-field magnitudes occurred in the lumbo-sacral region for all configurations. Larger electrode separations…

The use of low-level electromagnetic fields to suppress atrial fibrillation.

This animal study tested whether extremely low-level pulsed EMF (0.034 μG, 0.952 Hz) could suppress induced atrial fibrillation in 17 anesthetized dogs. EMF applied to cervical vagal trunks or across the chest was reported to suppress neural firing in the anterior right ganglionated plexi. The authors report that EMF…
