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 Qigong for 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.
Electroceutical Targeting of the Autonomic Nervous System. Autonomic nerves are attractive targets for medical therapies using electroceutical devices because of the potential for selective control and few side effects. These devices use novel materials, electrode configurations, stimulation patterns, and closed-loop control to treat heart failure, hypertension, gastrointestinal and bladder diseases, obesity/diabetes, and inflammatory disorders. Critical to progress is a mechanistic understanding of multi-level controls of target organs, disease adaptation, and impact of neuromodulation to restore organ function.
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, see The Rife Handbook of Frequency Therapy and Holistic Health.
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.

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.

See photobiomodulation section in Physical energies to the rescue of damaged tissues [PMC6600852]. The biological responses elicited by PBM raise the major question as to whether our cells may also use and process electromagnetic signals by themselves, instead of only sensing an exogenously applied electromagnetic radiation (light). A positive answer to this question came from the seminal discovery of Guenter Albrecht-Buehler in 1992.

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.

Bioelectromagnetic Platform for Cell, Tissue, and In Vivo Stimulation. Magnetogenetics is a new field that utilizes electromagnetic fields to remotely control cellular activity. In addition to the development of the biological genetic tools, this approach requires designing hardware with a specific set of demands for the electromagnets used to provide the desired stimulation for electrophysiology and imaging experiments. The rapid growth of research interest in magnetogenetics in the past decade has resulted in a broad range of bioelectromagnetic stimulation applications , creating a demand for sophisticated stimulus delivery systems.

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.

Improving Imaging of Cancerous Tissues by Reversing Time. Current high-resolution optical imaging technology allows researchers to see about 1 millimeter deep into the body. Beyond that, the light scatters and obscures the features, which is why we can’t see bones or tissue in the hand with a flashlight. To overcome this, Wang and his lab developed photoacoustic imaging, which combines light with acoustic waves, or sound, to form a sharper image, even several centimeters into the skin.

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.

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.

Pulsed Electromagnetic Field Stimulation in Osteogenesis and Chondrogenesis: Signaling Pathways and Therapeutic Implications. Mesenchymal stem cells (MSCs) are the main cell players in tissue repair and thanks to their self-renewal and multi-lineage differentiation capabilities, they gained significant attention as cell source for tissue engineering (TE) approaches aimed at restoring bone and cartilage defects. Pulsed electromagnetic fields (PEMFs) are currently used as a safe and non-invasive treatment to enhance bone healing and to provide joint protection. PEMFs enhance both osteogenic and chondrogenic differentiation of MSCs. Here, we provide extensive review of the signaling pathways modulated by PEMFs during MSCs osteogenic and chondrogenic differentiation. Overall, the application of PEMFs in tissue repair is foreseen: (1) in vitro: to improve the functional and mechanical properties of the engineered construct; (2) in vivo: (i) to favor graft integration, (ii) to control the local inflammatory response, and (iii) to foster tissue repair from both implanted and resident MSCs cells [PMCID: PMC7830993].

Because it is non-ionizing and non-invasive, Terahertz (THz)-based detection represents a very attractive tool for repeated assessments, patient monitoring, and follow-up.
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.

Recent studies have shown that the method has several secondary effects on local physiology and brain function beyond making the vasculature permeable to normally non-BBB penetrant molecules. This study uses functional MRI methods to investigate how FUS BBB opening alters the neurovascular response.
Ultrasound-mediated Drug Delivery to the Brain: Principles, Progress and Prospects. The blood-brain barrier (BBB) limits drug delivery to the central nervous system. When combined with microbubbles, ultrasound can transiently permeate blood vessels in the brain. This approach, which can be referred to as sonoporation or sonopermeabilization, holds significant promise for shuttling large therapeutic molecules, such as antibodies, growth factors and nanomedicine formulations, across the BBB. We here describe the basic principles of BBB permeation using ultrasound and microbubbles, and we summarize several (pre-) clinical studies showing the potential of BBB opening for improving the treatment of cancer and neurodegenerative disorders.

“Nanosized Voltmeter” Enables Cellular-Wide Electric Field Mapping. Previously, all biological measurements of intracellular electric fields (E fields), using voltage dyes or patch/voltage clamps, were confined to cellular membranes, which account for <0.1% of the total cellular volume. These membrane-dependent techniques also frequently require lengthy calibration steps for each cell or cell type measured. A new 30-nm "photonic voltmeter", 1000-fold smaller than existing voltmeters, enables, to our knowledge, the first complete three-dimensional E field profiling throughout the entire volume of living cells. These nanodevices are calibrated externally and then applied for E field determinations inside any live cell or cellular compartment, with no further calibration steps. The results indicate that the E fields from the mitochondrial membranes penetrate much deeper into the cytosol than previously estimated, indicating that, electrically, the cytoplasm cannot be described as a simple homogeneous solution, as often approximated, but should rather be thought of as a complex, heterogeneous hydrogel, with distinct microdomains [PMCID: PMC1929021].
