This double-blind study tested the effects of pulsating electromagnetic field (PEMF) therapy sessions on the changes in peripheral cardiovascular function in a group of aging adults after 12 weeks of treatment. Each therapy session involved 15 min of exposure to low-frequency PEMF with asymmetrical waveforms emitted by the Impulser™ Pro mattress. The treatment was provided 5 days per week for a total of 60 sessions. Resting blood pressure and arterial stiffness index were determined for peripheral cardiovascular function. Fifty-four older men and women (mean age 59.8 ± 3.5 yrs) completed the entire protocol involving either the PEMF or a sham treatment. The results include statistically significant reductions in systolic and pulse blood pressure, while no significant difference in diastolic pressure or the index of arterial stiffness was observed. These findings suggest that the PEMF treatment might be linked to improvements in peripheral resistance or circulation.
