Laser Therapy
Laser Therapy is known by many terms, including cold or low-level laser therapy (LLLT). Recently, experts have chosen photobiomodulation therapy (PBMT) as a more accurate term that describes the therapeutic use of red and near-infrared wavelengths of light energy from laser OR light emitting diodes (LEDs) that interact with photoreceptors to produce photochemical reactions that have a positive effect on cellular metabolism and recovery from damage and inflammation.
Light Spectrum in Laser Therapy
The effectiveness of wavelengths of light with respect to photobiomodulation therapy can be characterized by the action spectra of the target photoacceptors (e.g. cytochrome c oxidase), that determine the positive biological responses such as increased metabolism, cellular regeneration and immunomodulation. The most clinically effective wavelength ranges are in the red (630-680 nm) and near infrared spectra (810-840 nm). Wavelength is one critical parameter of light among other factors such as dosage or energy density (J/cm2), treatment time and light delivery in pulses (cycles per second or Hz) in determining the efficiency of absorption, depth of penetration and ultimately the clinical outcomes. The effects of photobiomodulation are cumulative and can be clinically evident immediately after treatment or over a period of days.
Class III vs Class IV Lasers
The medical subject headings (MeSh) for Laser Therapy is now called photobiomodulation therapy (PBMT). Light emitting diodes (LEDs) and other sources of light have been proven to be clinically effective so referencing only lasers is not accurate anymore. The definition of PBMT mentions that if lasers are used they must be less than 500 mW to avoid a thermal reaction and inhibition of healing. Thus, any single laser diode with the goal of photobiomodulation should be a Class 3B when contacting the skin to ensure optimal penetration and provide enough stimulatory healing energy but not cause thermal tissue damage.
PEMF Technology
Magnets have been used for the alleviation of chronic pain, metabolic disorders, circulatory problems and for treating muscle tension for many centuries. To answer some of the questions that the critical mind might have, consider the following abstracts from studies and other publications on magnetic therapy.
Witeseyn Shahsean October 4, 2020 Deborah L. Marshall DVM, CVA, CVC
Shahsean at the time of this incident was a 32 year old, 3/4 Arab 1/4 Morgan gelding. On June 6, 2018 he came out of his stall with a clear “profile” to the R front leg. On ultrasound there was definite damage to the superficial flexor tendon in this leg though the horse did not seem particularly uncomfortable. He was treated conservatively with a micro-stim and it was decided to leave him on turn out as he has access to his stall, is quiet in pasture and gets rather agitated when kept in. Shahsean seemed comfortable and appeared to be doing well.

Effects of magnetic therapy

“Studies conducted in several countries show that magnetic contact with human blood supply activates the ion content and creates a weak current. An increase number of centers of crystallization occurs, directly proportional to the strength of the field, reports Dr. Bansal. He believes that the process of ionization is hastened which alleviates the danger of blood clotting and stimulates the flow of blood to the arteries and veins. Magnetic flux in the blood increases the number of red corpuscles and strengthens inactive and decaying arteries; the movement of hemoglobin is accelerated and calcium and cholesterol deposits are held to a minimum, all of theses clinically observed by Dr. Bansal and associates. Magnetism has been demonstrated to stimulate other fluids in the body as well (Bansal, 1983, 1990)…Dr. Bansal enumerates effects of magnetic fields on the biological system:

  • Secretion of hormones and other fluids is promoted and the positive effect is exercised on the working of the glands in the entire secretory apparatus;
  • Function of the automic nerves are normalized and strengthened, improving the function of all internal organs;
  • Build up of new cells and rejuvenation of tissues; and
  • A stabilizing of the genetic code (92-93).

Highly advanced electromagnetic devices used in human medicine

“Magnetic resonance imaging (MRI), is used to take detailed images of internal body parts, and for mapping the brain, and exploratory surgery, etc. and which is rapidly replacing X-rays that place us at risk to cellular damage from adverse radiation.”(87) for diagnostic purposes MRI’s are also used for breast imaging in the detection of cancer. “Terafield & Diapulse electromagnetic devices for relief of pain and edema, approved or registered by the FDA in 1972 and used by more than 1,000.00 hospitals, colleges, and health care centers”(88).

“The earth's magnetic field has a significant impact on all living things and that life itself is dependent on magnetic energy. A striking example of this connection was discovered by NASA. The first astronauts to orbit earth outside of the earth's magnetic field returned home sick and weakened. NASA scientists discovered their illness was caused by a lack of magnetism and solved the problem by placing magnets in spacecraft and space suits” (96).

“The moons micro pulsations-from 0.1 to 35 Hertz-are in perfect harmony with the electro biochemical impulses of man that they helped to develop during evolution”(97).

“Lower frequencies are even more effective for treatment as they are able to achieve resonance more easily when interacting with the natural resonance frequency of body tissues which are under 25 Hz”(145).

Literary/scientific evidence of magnetic energy

Rose, Peter. “Magnetic Therapy Illustrated: Natural Healing and Pain Relief Using Magnets”. Ulysses Press. California: Berkley: 2001.

“What magnets can do is help reduce the pain and improve the blood flow, thereby accelerating chemical re-building and the removal of waste products” (p.71).

Origins of magnetic therapy

“The magnetic properties of lodestones (naturally magnetic rocks) were recorded by the Greek philosopher Thales of Miletus in around 600 BCE. (7)

”The ancient Chinese…certainly used magnets and magnetic material to improve the flow of chi, the internal energy that flows around channels of meridians in the body.” (7)

”The Atharva-Veda, the sacred ancient writings of Hinduism, refers to magnets being used to stop bleeding, while Cleopatra supposedly wore a small magnet on her forehead to preserve the fabled beauty.” (7).

“Paracelsus, the Swiss alchemist and physician wrote: “There are qualities in a magnet and one of these qualities is that the magnet also attracts all material humors that are in the human system. The magnet therefore is very useful in all inflammations, influxes and ulcerations in the diseases of the bowels and uterus….” (47).

“…The physician Dr. William Gilbert reputedly prescribed magnets for Queen Elizabeth I.”(7).here

Scientific studies and articles

Result of a study conducted at the “Institute for Microcirculation in Berlin, Germany”:

The tissue of the group that received electromagnetic stimulation showed an increase in blood circulation and an improved oxygen supply at all times when scientific measurements were taken.

The QRS, Quantron Resonance System, is backed by 30 years of scientific knowledge, numerous clinical trials and empirical tests. There is a broad range of applications for treatment with the pulsating electromagnetic fields of the QRS.

In summary this study dealt with examining the following problems:

“Osteoarthritis of the knee joint is a disseminated degenerative disease, especially in adult, which mostly develops due to the imbalance of use and constitutional capacity of the joint tissues. Clinical symptoms are stiffness and pain, and in the long term cases also knee joint instability. The standard therapy up to now is rather symptomatic than causal, mostly physical therapy and analgesic medicines” (p.1).

In summary the findings state the following:

“The results are astonishing for the medical profession….For the User and the QRS specialist; it is not so quite so astonishing that this (unspecified) therapy delivers such clear results in a narrowly defined diagnosis. This makes QRS® a real alternative in therapy…” (p.29).
