Effects of Pulsed Electromagnetic Fields (PEMFS) On Cerebral Haemodynamics

Summary

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.

Conditions

• Cerebral Hemodynamics
• Cognitive Change

Interventions

DEVICE

Pulsed Electromagnetic Fields Therapy (Dominant leg)

Participants of this arm will be exposed to 10 minutes of Pulsed Electromagnetic Fields on their dominant leg once a week for a total of 6 weeks. A minimum of 5-day and maximum of 9-day interval between each treatment session shall be followed. The PEMF device produces pulsed magnetic fields at flux densities up to 1.5 mT peak.

DEVICE

Pulsed Electromagnetic Fields Therapy (Non-dominant leg)

Participants of this arm will be exposed to 10 minutes of Pulsed Electromagnetic Fields on their non-dominant leg once a week for a total of 6 weeks. A minimum of 5-day and maximum of 9-day interval between each treatment session shall be followed. The PEMF device produces pulsed magnetic fields at flux densities up to 1.5 mT peak.

DEVICE

Sham Therapy (Control)

Participants of this arm will be not be exposed to the fields. Sham treatment will utilise the same PEMF apparatus for 10 minutes, but in non-operational mode, which is indistinguishable from when the apparatus is in operation. Duration of intervention is 6 weeks. A minimum of 5-day and maximum of 9-day interval between each treatment session shall be followed.
