The different variations of PEMF products

Since the turn of this century, a number of electrotherapeutic, magneto therapeutic and electromagnetic medical devices have emerged for treating a broad spectrum of trauma, tumors and infections with static and PEMFs. The acceptance of PEMF products in clinical practice has been very slow in the medical community. Practitioner resistance seems largely based on confusion of the different modalities, the wide variety of frequencies employed (from ELF to microwave) and the general lack of understanding of the biomechanics involved. The current scientific literature indicates that short, periodic exposure to pulsed electromagnetic fields (PEMF) has emerged as the most effective form of electromagnetic therapy.

 

The ability of PEMFs products to affect pain is dependent on the ability of PEMFs to positively affect human physiologic or anatomic systems. Research is showing that the human nervous system is strongly affected by therapeutic PEMFs. Behavioral and physiologic responses of animals to static and extremely low frequency (ELF) magnetic fields are affected by the presence of light. Light strengthens the effects of PEMFs.

 

One of the most reproducible results of weak, extremely low-frequency (ELF) magnetic field (MF) exposure is an effect upon neurologic pain signal processing. PEMF products have been designed for use as a therapeutic agent for the treatment of chronic pain in humans. Recent evidence suggests that PEMFs would also be an effective complement for treating patients suffering from acute pain. Static magnetic field devices with strong gradients have also been shown to have therapeutic potential. Specifically placed static magnets reduce neural action potentials and alleviate spinal mediated pain. The placebo response may explain as much as 40% of an analgesia response. The central nervous system mechanisms responsible for the placebo response are an appropriate target for magnetic therapies. Magnetic field manipulation of cognitive and behavioral processes is seen in animal behavior studies and in humans. This may also be one of the mechanisms of the use of MFs in managing pain.
