1.2. Effects of Infrared Light on Health – From a mechanistic point of view, IR can affect living tissues from cellular to organ system level. At a molecular level, IR affects the rotation of molecules contained in body fluids and tissues. The potential clinical and physiological effect depends on the composition of the tissue and the proportion of biomolecules contained in body fluids,

At the cellular level, the interaction between IR and living tissue boils down to heat–induced alterations of cell membrane potentials by means of a rise in intracellular Ca 2+ levels. This occurs due to increased membrane permeability for Ca 2+ and increased Ca 2+ release from the endoplasmic reticulum as a response to reactive oxygen species (ROS) generated because of the exposure of cells to radiation,

At the tissue level, a rise in the levels of Nitric Oxide (NO), an endogenous antioxidant substance countering the production of ROS, is associated with oxidative stress reduction and vasodilation. Simultaneously, it stimulates growth factor production and extracellular matrix deposition promoting tissue repair,

  • In this sense, IR-associated improvement in blood circulation can promote injury and pressure sores healing, decrease muscle spasms and improve the sensory nerve conduction velocity, and potentially increase endorphins modulating pain—the latter might be regulated by other factors as well,
  • At large, exposure to IR has been considered as an analog of exercise conveying similar benefits to either athletes or patients receiving IR sessions.

Certainly, several aspects of the interaction of IR with the neuromusculoskeletal tissue are yet to be clarified. A summary of the hypothesized and investigated biological and clinical effects of IR therapy with a focus on the musculoskeletal system is presented in Figure 1, Schematic presentation of IR therapy means of treatment and hypothesized biological and clinical effects with a focus on the musculoskeletal system. Briefly, exposure to infrared radiation leads to an intracellular increase in reactive oxygen species (ROS) and a subsequent rise in nitric oxide (NO) synthesis and calcium intracellular levels (Ca 2+ ).

  • Eventually, this decreases oxidative stress, induces vasodilation and stimulates growth factor production and extracellular matrix deposition leading to tissue repair.
  • Abbreviations: reactive oxygen species: ROS, nitric oxide: NO, calcium: Ca 2+,
  • IR consists of a promising complementary treatment for a wide range of musculoskeletal conditions, including knee osteoarthritis, fibromyalgia, chronic low back pain, chronic myofascial syndrome, sacroiliitis, and Gulf War Illness,

Infrared therapy can be delivered with light-emitting devices (photobiomodulation), wires, ceramic materials, and IR saunas. In a number of studies, infrared therapy has also been associated with clinical and perceptual improvement in chronic-pain-related psychosomatic symptoms such as fatigue and insomnia,

Are infrared radiations used in the treatment of muscle aches?

The therapeutic effects of heat – Infrared radiation can promote local blood circulation and reduce muscle tension. Examples of traditional medical applications of infrared radiation include the relief of muscle pain and tension, as well as the treatment of autoimmune diseases or wound-healing disorders.

Which EM wave is used in physiotherapy?

Infra-red rays are electromagnetic waves, the heat energy obtained from the rays are used to relieve pain.

What are the uses of infrared rays?

Infrared radiation uses – Infrared has a variety of uses and applications. Some common uses for IR include heat sensors, thermal imaging and night vision equipment. In networking, wired and wireless operations use infrared light. Remote controls use near-infrared light, transmitted with LEDs, to send focused signals to home-entertainment devices, such as televisions. This image shows the location of infrared and visible light on the electromagnetic spectrum. In addition, astronomers extensively use infrared to observe objects in space that the human eye can’t detect, such as molecular clouds, stars, planets and active galaxies.

Which of the following radiations are used to treat muscle ache? Explanation: Infrared rays are used to treat muscle aches.

What is infrared radiation in physiotherapy?

Infrared radiation physiotherapy is an innovative therapy that is used to manage acute or chronic pain in patients. In this therapy, various wavelengths of light are focused to the parts of the body that have injuries.

What frequency is used in physiotherapy?

Introduction – Ultrasound (US) is a form of mechanical energy (not electrical), and therefore, strictly speaking, not really electrotherapy at all, but does fall into the Electro Physical Agents grouping. Mechanical vibration at increasing frequencies is known as Sound Energy.

The normal human sound range is from 16 Hz to something approaching 15-20,000 Hz (in children and young adults). Beyond this upper limit, the mechanical vibration is known as ultrasound, The frequencies used in therapy are typically between 1.0 and 3.0 MHz (1 MHz = 1 million cycles per second). Sound waves are longitudinal waves consisting of areas of compression and rarefaction,

Particles of a material, when exposed to a sound wave will oscillate about a fixed point rather than move with the wave itself. As the energy within the sound wave is passed to the material, it will cause oscillation of the particles of that material.

  1. Clearly any increase in the molecular vibration in the tissue can result in heat generation, and ultrasound can be used to produce thermal changes in the tissues, though current usage in therapy does not focus on this phenomenon,
  2. The Ultrasound instrument consists of a high-frequency generator.
  3. This is connected to a treatment head or transducer circuit by a co-axial cable for the production of ultrasound waves.1 MHz or 3MHz frequency is needed.

When these varying potential difference or frequency applied on quartz crystal, via a linking electrode, the crystal being fused to the metal front plate of the treatment head. Any changes in the shape of crystal(Compressed and Relaxed), produces an ultrasonic wave.

  1. It generates ultrasound waves by a Piezoelectric effect.
  2. In addition to thermal changes, the vibration of the tissues appears to have effects which are generally considered to be non thermal in nature, though, as with other modalities (e.g.
  3. Pulsed Shortwave) there must be a thermal component however small.

As the US wave passes through a material (the tissues), the energy levels within the wave will diminish as energy is transferred to the material. The energy absorption and attenuation characteristics of US waves have been documented for different tissues (see absorption section).

Why do physiotherapists use shock waves?

The main benefits of shockwave are pain relief and restoration of function. Shockwave therapy has been shown to be an effective treatment modality for a range of common tendon complaints including plantar fasciitis, Achilles tendinopathy and tennis elbow.

What is magnetic therapy in physiotherapy?

Magneto-therapy, also is called magnetic field therapy and bioenergetic therapy, is an alternative treatment that uses magnets of various sizes and dynamic strengths that are placed on the body to relieve pain and cure diseases ( 1 ).

What are two different uses of infrared radiation?

Infrared – Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark. The heating effect of IR can cause burns to the skin.

What are 5 benefits of infrared radiation?

Why is Infrared Therapy Widely Used Today? – Infrared therapy is widely used in the fields of medicine, dentistry, veterinary medicine, and in autoimmune diseases, to name a few. The therapy is safe and natural, which enables it to be offered as an alternative treatment for various health conditions like muscle pain, joint stiffness, and arthritis, to name a few.

Is heat the same as infrared radiation?

NASA – Infrared Light

Light comes to us in waves

Light comes to Earth in waves. Some of the waves are long. Some of the waves are short. The waves are all different in their size. We can see some of the waves in the form of color. But other waves we cannot see with our eyes. But we can see them with special cameras.

Infrared light is one of the lights we can see with special cameras. Infrared light shows us how hot things are. It can also show us how cold things are. But it all has to do with heat. Our bodies give off heat in waves. Animals like dogs and cats give off heat too. With special infrared cameras, you can see the heat.

It makes things that are hot look like they are glowing. In infrared light, hot things look bright yellow and orange. Items that are colder, such as an ice cube, are purple or blue. We use infrared cameras to help us see things. NASA scientists use infrared to help predict weather.

Rescue workers use them to find people who need help. How can we “see” using the Infrared? Since the primary source of infrared radiation is heat or thermal radiation, any object which has a temperature radiates in the infrared. Even objects that we think of as being very cold, such as an ice cube, emit infrared.

When an object is not quite hot enough to radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits.

The Electromagnetic Spectrum

To make infrared pictures, we can use special cameras and film that detect differences in temperature, and then assign different brightness or false colors to them. This provides a picture that our eyes can interpret. Humans may not be able to see infrared light, but did you know that snakes in the pit viper family, like rattlesnakes, have sensory “pits”, which are used to image infrared light? This allows the snake to detect warm blooded animals, even in dark burrows! Snakes with 2 sensory pits are even thought to have some depth perception in the infrared! Many things besides people and animals emit infrared light – the Earth, the Sun, and far away things like stars and galaxies do also! For a view from Earth orbit, whether we are looking out into space or down at Earth, we can use instruments on board satellites.

Building and tree – visible light, and same building and tree on infrared film

We know that many things emit infrared light. But many things also reflect infrared light, particularly near infrared light. Near infrared radiation is not related to the temperature of the object being photographed – unless the object is very, very hot.

  • Infrared film ‘sees’ the object because the Sun (or some other light source) shines infrared light on it and it is reflected or absorbed by the object.
  • You could say that this reflecting or absorbing of infrared helps to determine the object’s ‘color’ – its color being a combination of red, green, blue, and infrared! This image of a building with a tree and grass shows how Chlorophyll in plants reflect near infrared waves along with visible light waves.

Even though we can’t see the infrared waves, they are always there. The visible light waves drawn on this picture are green, and the infrared ones are pale red. To read this entire article, please visit the, : NASA – Infrared Light

What are the 2 types of radiation heat?

Thermal Radiation – Thermal radiation is one type of electromagnetic radiation, specifically one that transfers heat often in the form of infrared waves. Generally, thermal radiation and infrared waves are referred to simply as “heat”. Since heat is carried by electromagnetic waves, it does not need a physical medium to transfer it. Figure 4. A dog as seen in the infrared spectrum. Objects emit thermal radiation because they’re at a temperature that isn’t perfectly cold ( absolute zero Kelvin). The thermal energy makes an objects’ molecules wiggle. Molecules have electric charge, and that wiggling makes changing electric fields, which makes for radiation.

The higher the temperature, the faster the wiggling of the molecules. Objects hotter than ~500°C (773 K) start to emit visible light. Objects cooler than ~500°C emit radiation that not visible to the naked eye (see Wiens Law for more information]]. Infrared cameras are able to pick up this invisible radiation and digitally convert it into a visible image (such as the one shown in Figure 4).

Sometimes this radiant heat is visible. For example, a candle radiates heat. It also gives out visible light, which corresponds with the temperature of the flame. The flame burns hottest at the wick, and gives off blue or white light as it is on the higher end of the visible light spectrum.

What are 2 examples of radiation heat?

thermal radiation, process by which energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it. Britannica Quiz Physics and Natural Law The rate at which a body radiates (or absorbs) thermal radiation depends upon the nature of the surface as well. Objects that are good emitters are also good absorbers ( Kirchhoff’s radiation law ). A blackened surface is an excellent emitter as well as an excellent absorber.

  1. If the same surface is silvered, it becomes a poor emitter and a poor absorber.
  2. A blackbody is one that absorbs all the radiant energy that falls on it.
  3. Such a perfect absorber would also be a perfect emitter.
  4. The heating of the Earth by the Sun is an example of transfer of energy by radiation.
  5. The heating of a room by an open-hearth fireplace is another example.

The flames, coals, and hot bricks radiate heat directly to the objects in the room with little of this heat being absorbed by the intervening air. Most of the air that is drawn from the room and heated in the fireplace does not reenter the room in a current of convection but is carried up the chimney together with the products of combustion.

What are the three types of heat radiation?

Introduction to the three types of heat transfer – Heat is transferred via solid material (conduction), liquids and gases (convection), and electromagnetic waves (radiation), Heat is usually transferred in a combination of these three types and randomly occurs on its own.

What does radiation do to muscle tissue?

Radiation treatment can make your muscles and soft tissues (for example, ligaments and skin) stiff and tight. This condition is called radiation induced fibrosis. When your muscles are not moving properly they can cause pain or limit movement in other parts of your body.

Does radiation destroy muscle?

By Nicholas Weiler | UCSF.edu | April 18, 2019 Newly discovered radiation-resistant stem cells are normally rare and inactive (left), but they take on a major role in muscle repair when regular stem cells are damaged by radiation (right). Credit: Brack lab / UCSF.

  1. Muscle damage is a common side effect of radiation therapy for cancer treatment, and is made worse because the very stem cells responsible for repairing injured muscles typically bear the brunt of radiation damage.
  2. Now UC San Francisco researchers have discovered a new type of stem cell in mouse muscles that is resistant to radiation and other forms of cellular stress.

The findings have implications for improving recovery for cancer patients undergoing radiotherapy and could even lead to treatments to protect future astronauts from the ravages of deep-space radiation. Annarita Scaramozza, PhD, of the UCSF Department of Orthopaedic Surgery, discovered the small population of stem cells — identifiable by their expression of a gene called Pax3 — which normally remain inactive within mouse muscles. Annarita Scaramozza, PhD, discovered the small population of stem cells that activate after radiation. “It was remarkable to see how these reserve cells that we’d previously overlooked were able to withstand levels of radiation that severely damaged all other stem cells, and then wake up and start regrowing the damaged muscles,” Scaramozza said.

They were like superhero stem cells.” The results were published April 18 in Cell Stem Cell, alongside a second study showing that these resilient reserve stem cells are not just resistant to radiation, but also take over when regular stem cells are damaged by environmental toxins found in plastics and other pollutants.

Scaramozza and colleagues in the laboratory of Andrew Brack, PhD, also found that regular stem cells can be made radiation-resistant by treating them with anti-oxidizing agents that are well tolerated in humans. Read more at UCSF.edu

What are the side effects of radiation therapy on muscles?

Stiff joints and muscles – Radiotherapy can sometimes make your joints and muscles in the area being treated feel stiff, swollen and uncomfortable. Exercising and stretching regularly can help to prevent stiffness. Tell your care team if joint or muscle stiffness a problem. They may refer you to a physiotherapist, who can recommend exercises for you to try.

Who should not use red light therapy?

When should I see my healthcare provider? – If you notice these signs after LED light therapy, contact your healthcare provider:

Hives, Inflammation. Pain. Rash or redness.

A note from Cleveland Clinic LED light therapy is a non-invasive, pain-free treatment for multiple skin concerns and conditions. You can have this treatment at a spa, your dermatologist’s office or buy an at-home device. While LED light therapy is generally safe, consult your dermatologist before trying this treatment.

Is infrared therapy safe?

How does infrared therapy work? – Infrared light penetrates to the inner layers of the skin at about 2 to 7 centimeters deep. Hence, it reaches the muscles, nerves and even the bones. Many studies have shown that a frequency of infrared light, with wavelengths from 700 to 1,000 nanometers, is best used for healing inflammatory conditions.

The use of electricity for healing purposes began in 2,750 BC when people used electric eels to give electric shocks. Electricity and magnetism were used in people with just little success. However, in 1975, transcutaneous electrical stimulation (TENS) was developed to treat chronic pain. It was not until recently that infrared therapy was developed to improve wound healing, reduce the pain caused by arthritis, boost endorphin levels, and bioactivate neuromodulators.

Infrared therapy technology allows people to harness the benefits of the sun, without being exposed to harmful ultraviolet rays. Also, infrared therapy is safe and effective, without adverse side effects. As a matter of fact, infrared light is safe and is used even for infants in the neonatal intensive care.

Infrared light is absorbed by the photoreceptors in cells. Once absorbed, the light energy kickstarts a series of metabolic events, triggering several natural processes of the body on a cellular level. The key to the efficacy of infrared light therapy may be nitric oxide, a gas that is vital to the health of the body’s arteries.

Nitric oxide is a potent cell signaling molecule that helps relax the arteries, battles free radicals to reduce oxidative stress, prevents platelet clumping in the vessels, and regulates the blood pressure. Hence, this molecule enhances blood circulation to deliver vital nutrients and oxygen to damaged and injured tissues in the body.

What are the side effects of infrared radiation?

Near‐Infrared Exposure and Cataracts – The most common eye disease associated with near-infrared radiation is cataracts. Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina.

Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging. Cataracts caused by near‐infrared radiation have been noted historically in glassblowers and furnace workers. Radiation between 800 and 1,200 nm is most likely responsible for temperature increases in the lens itself because of its spectral‐absorption characteristics.

Visible wavelengths may also contribute to the problem, since the heat absorbed by the iris could result in heat transfer to the lens.

What type of EM waves is medical treatment?

EMF of lower frequencies up to 200 MHz is commonly used in medicine for diagnosis and therapy.

Which electromagnetic wave is used in medical treatment?

What are medical x-rays? – X-rays are a form of electromagnetic radiation, similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body.

If x-rays traveling through the body also pass through an x-ray detector on the other side of the patient, an image will be formed that represents the “shadows” formed by the objects inside of the body. One type of x-ray detector is photographic film, but there are many other types of detectors that are used to produce digital images.

The x-ray images that result from this process are called radiographs. The electromagnetic spectrum. X-rays have higher energy than visible light. Credit: iStock

Which EM waves are used as medical treatments and why?

Infrared radiation – Infrared radiation is used in thermal imaging to produce a thermogram – an image of the body showing areas of different temperature. 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.

What waves are used in medical treatment?

The radio waves are sent through needles inserted into tumor tissue and may kill cancer cells. Radio waves are also used in MRI to create detailed images of areas inside the body.
