Energy Medicine is the use of electromagnetism in medicine for diagnosis, treatment, prevention, and wellness. Nikola Tesla is credited as being the first to publish research results on the use of high frequency electrical currents in medical applications. His benchmark High Frequency Oscillators for Electro-therapeutic and Other Purposes was published in 1898. Since that time, electromedicine has had a checkered history of acceptance by governmental regulatory agencies and the established western medical community.
For energy-based medical practices and therapies such as Qigong and Tai Chi that do not require technology, see Integrative Medicine and Medical Qigong Therapy, Getting Started with Qigong, and Cancer. Introductory books, articles, and information on Energy Medicine can be found on Scientific Basis of Qigong and Energy Medicine and Bioenergetic Basis of Life. This page describes the use of electromagnetic technology in medical practice and bioelectromagnetic research.
Frequency Medicine, Frequency Therapy, Electromedicine, Electrotherapy, Electromagnetic Healing, Bioelectromagnetic Medicine, and Electromagnetic Medicine are all terms applied to the use of portions of the electromagnetic spectrum such as Extremely Low Frequency (ELF) , Radio Frequency (RF), InfraRed (IR), visible light, or Ultra Violet (UV) band to affect the health and well-being of humans. Devices based upon particular frequencies of the electromagnetic spectrum have a wide variety of healing and health improvement benefits such as curing illness, relieving pain, and restoring function. These devices which operate by delivering an electromagnetic pulse of a particlar frequency for a particular amount of time have been found to provide the ideal, non-invasive therapy. Frequency Medicine is poised to become a dominant force in medicine in the 21st Century.
For an overview of the medical use of electromagnetic (EM) frequencies for therapy and healing, and specific EM therapeutic methods and tools, see Healing with Electromedicine and Sound Therapies. For even more comprehensive information on energy-based technologies, devices, and their use for therapy, complementary therapies and how to use them, and holistic health, seeThe Rife Handbook of Frequency Therapy and Holistic Health.
Crash Course in Frequency Therapy (video: 12:41). Frequency devices typically work by targeting a pathogen's mortal oscillatory rate (MOR) to disable or kill it. Pathogens can be oscillated to destruction by applying resonant frequencies that cause the pathogen to lose it's integrity. In addition, many frequency devices have therapeutic and healing effects of cell regeneration and stimulation of the immune response.
Bioelectromagnetic Medicine: Specific electromagnetic (EM) frequencies modulate cellular function to restore or maintain health. Ultrasmall magnetic intensities are biologically significant which suggests that EM signaling is endogenous to cell regulation, and consequently that the remarkable effectiveness of EM resonance treatments reflects a fundamental aspect of biological systems. Organisms contain mechanisms for generating biologically useful electric signals.

Neuromuscular electrostimulation techniques: historical aspects and current possibilities in treatment of pain and muscle waisting. The pain relieving action of electricity is explained in particular by two main mechanisms: first, segmental inhibition of pain signals to the brain in the dorsal horn of the spinal cord and second, activation of the descending inhibitory pathway with enhanced release of endogenous opioids and other neurochemical compounds (serotonin, noradrenaline, gamma aminobutyric acid (GABA), acetylcholine and adenosine). The modern electrotherapy of neuromusculo-skeletal pain is based in particular on the following types: transcutaneous electrical nerve stimulation (TENS), percutaneous electrical nerve stimulation (PENS or electro-acupuncture) and spinal cord stimulation (SCS).
Energy-based technologies are accepted by the medical community as essential tools for diagnosis. However, energy therapies, research, and clinical applications and trials have not been as widely embraced (although this is slowly and inexorably changing -- see Western Medicine's Increasing Acceptance of Qigong and Energy Medicine).
The following is a partial list of energy-based technologies and therapies. It is further evidence of the acceptance of Energy Medicine by Western Medicine. For a comprehensive treatment of energy therapies, see The Rife Handbook of Frequency Therapy and Holistic Health.

Systematic studies have demonstrated that acupuncture or electroacupuncture (EA) analgesia is based on their accelerating endogenous opioid release to activate opioid receptors and that EA of different frequencies is mediated by different opioid receptors in specific areas of the central nervous system.

We speculate that continuous genuine EA stimulation can modify the coupling of spontaneous activity in brain regions that play a role in modulating pain perception.

Bioelectrography is a new and controversial field within physics whose purpose is to study the electric emissions of objects and living organisms. The method used in bioelectrography is called the Gas Discharge Visualization (GDV) technique. It is a more advanced technique than Kirlian photography and has been accepted as a medical technology by the Russian Ministry of Health. It creates a computer model inreal time of the energies measured by GDV, and is thought to be able to perceive 'imbalances' in energy fields which can then be used as a tool for medical diagnosis.
Technically, GDV is capturing the image of gas discharge during exposure to EMF. The cells exposed to the EMF produce a burst of electron-ion emission and optical radiation light quanta in the visual and ultraviolet light regions of the EM spectrum. These particles and photons initiate electron-ion avalanches, which create the gas discharge along the dielectric surface. A spatial distribution of discharge channels is registered via glass plate by an optical system with a CCD TV camera, and then it is digitized. The avalanche effect amplification of the object response can only occur in ionized gas and does not work in a vacuum.

Neuromuscular electrostimulation techniques: historical aspects and current possibilities in treatment of pain and muscle waisting. The modern electrotherapy of neuromusculo- skeletal pain is based in particular on the following types: transcutaneous electrical nerve stimulation (TENS), percutaneous electrical nerve stimulation (PENS or electro-acupuncture) and spinal cord stimulation (SCS). In mild to moderate pain, TENS and PENS are effective methods, whereas SCS is very useful for therapy of refractory neuropathic or ischemic pain. In 2005, high tone external muscle stimulation (HTEMS) was introduced. In diabetic peripheral neuropathy, its analgesic action was more pronounced than TENS application. HTEMS appeared also to have value in the therapy of symptomatic peripheral neuropathy in end-stage renal disease (ESRD). Besides its pain-relieving effect, electrical stimulation is of major importance for prevention or treatment of muscle dysfunction and sarcopenia. In controlled clinical studies electrical myostimulation (EMS) has been shown to be effective against the sarcopenia of patients with chronic congestive heart disease, diabetes, chronic obstructive pulmonary disease and ESRD.
Imaging of live animals at microscopic resolution (intravital microscopy, IVM) represents a powerful tool for addressing such questions. IVM can reveal cellular responses over time and space and can be conducted under conditions closely approximating those of a natural environment. This is crucial because cellular behavior is influenced by many factors including cytokine gradients, interactions with other cellular and extracellular components, anatomical compartmentaliza- tion, and forces of fluid flow.
Recent advances in intravital imaging of dynamic biological systems. Intravital multiphoton microscopy has opened a new era in the field of biological imaging. Focal excitation of fluorophores by simultaneous attack of multiple (normally "two") photons generates images with high spatial resolution, and use of near-infrared lasers for multiphoton excitation allows penetration of thicker specimens, enabling biologists to visualize living cellular dynamics deep inside tissues and organs without thin sectioning.

Low-level laser (light) therapy (LLLT) has been used for nearly 50 years to enhance tissue healing and to relieve pain, inflammation and swelling.
"Photonic stimulation sounds like “Star Trek” medicine -- something out of the future that seems too far-fetched to exist in today’s world. However, quantum healing with near infrared light photons is a reality today and is poised to become an essential technology in medical practice for years to come. This powerful, effective, safe, and affordable technology is revolutionizing medical treatment for pain, many neurological disorders, and a wide variety of musculoskeletal and soft tissue maladies. Many health problems that had previously been notoriously difficult or even impossible to successfully manage can now benefit from photonic stimulation." This therapy is being used in diabetic and other neuropathies, sports and other injuries, plantar fascitis, cervical and lumbar disc disease, repetitive stress injuries, postoperataive pain, fibromyalgia, carpal tunnel syndrome, osteoarthritis, and other conditions."

Red/near-infrared irradiation therapy for treatment of central nervous system injuries and disorders. R/NIR irradiation therapy (R/NIR-IT) has not been widely adopted in clinical practice for CNS injury or disease for a number of reasons, which include the following. The mechanism/s of action and implications of penetration have not been thoroughly addressed. The large range of treatment intensities, wavelengths and devices that have been assessed make comparisons difficult, and a consensus paradigm for treatment has not yet emerged. Furthermore, the lack of consistent positive outcomes in randomised controlled trials, perhaps due to sub-optimal treatment regimens, has contributed to scepticism. This review provides a balanced précis of outcomes described in the literature regarding treatment modalities and efficacy of R/NIR-IT for injury and disease in the CNS.

Microwave Imaging in Medicine: Promises and Future Challenges. Medical microwave imaging has been the ultimate goal of numerous electromagnetic sensing explorations over the past several decades. The concept of using of non-ionizing microwave-frequency electromagnetic waves to image the human body – that is, to image the microwave dielectric properties or microwave scattering and absorption characteristics of tissue – has intrigued engineers and clinicians alike. The dielectric properties of human tissue are influenced by physiological factors of clinical interest, such as water content, temperature, and vascularization. Low-power microwaves can be used to sense and image these properties in a low-cost manner that poses no health risk to the patient.

Microwave Radiometry and Breast Cancer. The tissues of the body emit natural radiation in the microwave frequency band. The intensity of radiation is in direct proportion to the temperature of the tissue. Thus, microwave radiometry is a non-invasive means of detecting internal tissue temperature. Infrared thermography is a well-known method of superficial screening. Unfortunately, infra-red thermography has only a very limited depth of penetration – approximately 2 mm. Microwave radiometry detects signals at a much greater depth, ranging from 2 millimetres to seven centimetres, depending on the water content of the tissue. The breast, being soft tissue, provides an ideal organ for radiometry examination.

Microscopy is usually done in a laboratory on carefully prepared very thin samples and achieves resolutions better than micrometers. Medical imaging, by contrast, is usually performed on sizeable portions of the living human body, and resolutions are rarely better than 1 millimeter.
Over the last decade, there has been great progress in applying optical microscopy techniques to the human body in a medical setting. This push has been led by optical coherence tomography, which is now in mainstream use in ophthalmology and is soon to gain acceptance in cardiology. Optical coherence tomography is an optical analog of ultrasound – but it penetrates much less and resolves much more.

Optogenetics, the intersection between physics and neuroscience: light stimulation of neurons in physiological conditions. Neuronal stimulation by light is a novel approach in the emerging field of optogenetics, where genetic engineering is used to introduce light-activated channels. However, light is also capable of stimulating neurons even in the absence of genetic modifications through a range of physical and biological mechanisms. As a result, rigorous design of optogenetic experiments needs to take note of alternative and parallel effects of light illumination of neuronal tissues. Thus all matters relating to light penetration are critical to the development of studies using light-activated proteins. This paper discusses ways to quantify light, light penetration in tissue, as well as light stimulation of neurons in physiological conditions. We also describe the direct effect of light on neurons investigated at different sites.

Near infrared light therapy. Electrons are excited to increase production of energy (ATP) to stimulate normal cellular physiology.
Healing With Photons. Scientists believe that the mechanism of action of photonic stimulation is related to its ability to excite electrons within the mitochondria of cells in injured tissues. This process is thought to enable malfunctioning cells to resume production of ATP and stimulate the return of normal cellular physiology. Accompanying this is a more normal regulation of the autonomic nervous system and an increase in blood flow to injured tissues. A number of conditions have been successfully managed via this therapy.

Photothermal Ablation uses nanoparticles excited by light to burn away cancer cells. Metal nanoparticles have molecular appendages called ligands attached to them. The ligands then attach exclusively to chemical receptors on cancerous cells. When irradiated with infrared light, collective electron oscillations (plasmons) begin to resonate and the metal nanoparticles heat up, burning away the cancerous cells while leaving the surrounding healthy tissue unaffected. Reference: Plasmons resonate in atomic-scale metal particles.

Proton therapy is an innovative form of radiation treatment that allows for more conformed radiation doses delivered to cancerous tumors. Radiation therapy, while helpful in treating the tumor, often comes with side effects, some of which can be very harmful to growing and developing children. Proton therapy’s greatest benefit is that it is less damaging to the surrounding healthy tissue because it delivers most of its energy to a very narrow field at the location of the tumor.

The potential of terahertz imaging for cancer diagnosis: A review of investigations to date. The terahertz region lies between the microwave and infrared regions of the electromagnetic spectrum such that it is strongly attenuated by water and very sensitive to water content. Terahertz radiation has very low photon energy and thus it does not pose any ionization hazard for biological tissues. Because of these characteristic properties, there has been an increasing interest in terahertz imaging and spectroscopy for biological applications within the last few years and more and more terahertz spectra are being reported, including spectroscopic studies of cancer. The presence of cancer often causes increased blood supply to affected tissues and a local increase in tissue water content may be observed: this acts as a natural contrast mechanism for terahertz imaging of cancer. Furthermore the structural changes that occur in affected tissues have also been shown to contribute to terahertz image contrast. This paper introduces terahertz technology and provides a short review of recent advances in terahertz imaging and spectroscopy techniques. In particular investigations relating to the potential of terahertz imaging and spectroscopy for cancer diagnosis will be highlighted.

‘Good Vibrations’! Brain Ultrasound Improves Mood. A group from the Departments of Anesthesiology and Radiology at the University of Arizona Medical Center in Tucson, Arizona has investigated Transcranial Ultrasound (TUS) for modulating mental states in a pilot study in human volunteers suffering from chronic pain.They found improvement in subjective mood 10 min and 40 min after TUS compared to placebo. TUS can have safe neurophysiological effects on brain function, and is a promising noninvasive therapy for modulating conscious and unconscious mental states and disorders. They suggest TUS acts via intra-neuronal microtubules, which apparently resonate in TUS megahertz range.
The Role of Endobronchial Ultrasound in Lung Cancer Diagnosis and Staging: A Comprehensive Review. Endobronchial ultrasound (EBUS) technology is a relatively new bronchoscopic method of visualizing the tracheobronchial tree, the surrounding pulmonary parenchyma, and the mediastinal structures, with a particular role in lung cancer diagnosis, staging, and treatment.
Endobronchial Ultrasound (EBUS) Biopsy of Mediastinal Lymph Nodes. Mediastinoscopy is the ‘gold standard’ method for determining the presence of nodal metastases in the mediastinum. Generally performed as an outpatient surgical procedure, it is associated with a low rate of serious adverse effects (<1%) and the procedure is highly accurate, with false negative rates reported to be between 6% and 9%. Endobronchial ultrasound (EBUS) guided fine needle aspiration biopsy of mediastinal nodes offers a less invasive alternative for histologic sampling of the mediastinal nodes. The procedure has been widely adopted by pulmonologists and is poised to replace mediastinoscopy in the future. For thoracic surgeons, the technique can be easily learned and it may be important to do so if our specialty is to maintain its traditional and important role in the diagnosis and staging of thoracic malignancies.

Low-pressure pulsed focused ultrasound with microbubbles promotes an anticancer immunological response. High-intensity focused-ultrasound (HIFU) has been successfully employed for thermal ablation of tumors in clinical settings. Continuous- or pulsed-mode HIFU may also induce a host antitumor immune response, mainly through expansion of antigen-presenting cells in response to increased cellular debris and through increased macrophage activation/infiltration. Here we demonstrated that another form of focused ultrasound delivery, using low-pressure, pulsed-mode exposure in the presence of microbubbles (MBs), may also trigger an antitumor immunological response and inhibit tumor growth.
