What is the purpose of electromagnetic treatment?

In addition to immediate pain relief, the administration of electricity or its derivatives may assist tissue healing and regeneration by cell stimulation, removal of edema and inflammatory mediators, and angiogenesis. Many facts are known about body electricity and magnetism.

What are electromagnetic measures?

Basic electromagnetic measures have been used for centuries and are of 2 types: those that remove or mobilize body electricity and those that administer an electronic current or a derivative of a current (see Table 1). The former includes such simple measures as mineral soaking in hot water, copper bracelets, hot water, and needle insertion.

How do magnets affect the body?

We have known since the scientific work of Faraday in 1831 that a magnet brought perpendicular to an electric current in a wire will depolarize the ends of the wire and cause the electric current to move. 2,3 Because pain is, to a great extent, caused by “pooled” or “trapped” electricity, a magnet or magnetic energy wave brought near a pain site causes pooled electricity to mobilize. Magnets also likely attract iron in red blood cells and increase blood flow into a pain site, which promotes mobilization of pooled electricity and inflammatory mediators.

Is electromagnetic therapy intimidating?

First, the term “electromagnetic” may be intimidating to some practitioners. Few medical personnel have had extensive training in physics or engineering. Second, commercial marketing of electromagnetic devices has, in my opinion, limited a great deal of interest on the part of pain practitioners.

Can electromagnetic radiation be used as a substitute for pharmacotherapy?

Be very clear, however, that electromagnetic measures are complementary and not a substitute for the time-tested treatments of pharmacotherapy, nutrition, exercise, and surgery.

What is electromagnetic therapy?

Electromagnetic therapy, which is an alternative form of medicine that aims to treat disease by applying pulsed electromagnetic fields or electromagnetic radiation to the body. This type of treatment is used for a wide range of diseases such as nervous disorders, diabetes, spinal cord injuries, ulcers, asthma, etc.

What is the most important use of electromagnets in medicine?

But beyond all the applications of electromagnets in medicine, the most important use of these in hospitals is in magnetic resonance imaging, commonly known as MRI. It is used to get a detailed picture of the inside of the body, which helps diagnose a number of diseases.

Why are electromagnets important?

This is why, today, electromagnets in medicine play a key role in advanced treatments, such as hyperthermia treatments for cancer, implants and magnetic resonance imaging, to mention just three of the areas of greatest use.

Why are electromagnets used in medicine?

Due to their ability to generate very powerful magnetic fields, low resistance and high efficiency , electromagnets have often been applied in medicine and scientific equipment. This sector has experienced significant growth in recent years.

What is a magnetic resonance machine?

Magnetic resonance machines in hospitals and scientific instruments such as nuclear magnetic resonance spectrometers, mass spectrometers and also particle accelerators. RF range frequencies are also mainly used in medical applications.

What is the role of ion concentrations in biological electromagnetic waves?

Ion concentrations act as triggers with concomitant electric gradients being traced along signaling cascades until gene expression is changed in the nucleus. The idea that all living tissue is in motion, resonating in alternating fields (ELF EMF), is fundamental to the biologic electromagnetic paradigm.

What is the parameter used to describe an EMF?

Another important parameter used to describe or characterize an EMF is the wavelength, and because EMFs are typically conceptualized as waves with peaks and troughs, the wavelength is the distance between crests of a wave.

What is the difference between AC and EMF?

In AC current, the electricity is moving back and forth and, as a result , produces a dynamic magnetic field. The greater the current, the greater the magnetic field. An EMF by definition refers to a dynamic or fluctuating MF and contains both an electric and a magnetic field. A specification that often is referenced is the rate or frequency ...

What is a magnetic field?

A magnetic field (MF) is a magnetic force that extends out from a magnet and can be either static or dynamic. These MFs are produced by electric currents and specifically as a result of electron movement in 1 (DC) or 2 (AC) directions. In AC current, the electricity is moving back and forth and, as a result, produces a dynamic magnetic field.

Can nonthermal EMFs be harmful?

It is thought that nonthermal exogenous EMFs have the potential to exert significant biologic effects in living organisms. These effects can either be harmful or beneficial, depending on exposure parameters and susceptibility factors (bio-sensitivity).

Can EMFs travel through space?

All EMFs are capable of traveling through space at a great distance and can exert effects from afar. These fields carry energy and can be described either in terms of particles (photons) or waves, demonstrating characteristics of both.

Is radiation a short or long term exposure?

Various types of radiation exposure are of concern, including acute ( short duration) exposure to high-energy fields, which have been extensively studied. However, just as or possibly more important are the more prolonged (longer duration) exposures to non- or weak ionizing radiation found in common household, work, and recreational applications.

What are gamma rays?

Gamma rays. Gamma rays are emitted from the nuclei of atoms. They have high energy and can kill cancer cells, as well as bacteria on food. They can also be used as a medical tracer. When gamma rays are used as medical tracers, a chemical containing the rays is injected into the body of a patient.

How do X-rays help with cancer?

X-rays. X-rays can kill cancer cells. Directing an X-ray beam onto skin cancer cells, or cancer cells inside the body, can help to cure cancer. X-rays can also be used to produce images of the internal structure of the body, helping doctors to determine whether bones are broken or fractured.

Why do we use a CCD?

This helps doctors to diagnose patients, as parts of the human body may emit more infrared if they are hot due to infection or injury. A charged coupled device (CCD) absorbs infrared radiation to produce an image. Each pixel in the CCD detects the infrared radiation and the data can be processed using a computer.
