Effects of Pulsed Electromagnetic Fields (PEMFS) On Cerebral Haemodynamics

The investigators are looking to determine the effects of PEMFs device on cerebral blood flow and cognition in healthy volunteers. Through in vitro tests and in vivo animal studies, the investigators have shown that at an extremely low flux density (strength) of 1 millitesla (mT) and with short exposures of 10 minutes a week, PEMFs can recapitulate many of the healthful benefits of exercise without imparting a mechanical stress on the tissues and cells. In the first-in-man study, 10 healthy volunteers were exposed to PEMFs for 6 weeks with 10 minutes of field exposure per week, and experienced an average increase of 30% in leg strength. No side effects were reported. In this study, the investigators aim to understand the cerebral effects of an exercise mimetic (PEMFs) via the muscle milieu.
