Low intensity laser therapy does it work
Typical us frequencies from therapeutic equipment are 1 and 3 mhz though some machines produce additional frequencies (e.g. 0.75 and.5 mhz) and the longwave ultrasound devices operate at several 10s of khz (typically 40-50,000hz a much lower frequency than traditional us but still beyond human hearing range. The mathematical representation of the relationship. L where, v velocity, f frequency and l is the wavelength. Ultrasound beam, near field, far field and beam Non Uniformity. The us beam is not uniform and changes in its nature with distance from the transducer. The us beam nearest the treatment head is called the. Near field, the interference field or the Frenzel zone.
The energy absorption and attenuation characteristics of us waves have been documented for different tissues (see absorption section). Ultrasound bril waves, frequency - the number of times a particle experiences a complete compression/rarefaction cycle in 1 second. Typically 1 or 3 mhz (though there are devices which operate in the khz range - see comments on Low Frequency / Longwave ultrasound at the end of this paper). Wavelength - the distance between two equivalent points on the waveform in the particular medium. In happylogy an average tissue the wavelength @ 1mhz would.5mm and @ 3 mhz would.5. Velocity - the velocity at which the wave (disturbance) travels through the medium. In a saline solution, the velocity of us is approximately 1500 m sec-1 compared with approximately 350 m sec-1 in air (sound waves can travel more rapidly in a more dense medium). The velocity of us in most tissues is thought to be similar to that in saline. These three factors are related, but are not constant for all types of tissue. Average figures are most commonly used to represent the passage of us in the tissues.
cycles per second). Sound waves are, longitudinal waves consisting of areas of, compression and. 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. 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 (Williams 1987, baker et al 2001, ter. 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. 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.
Ultrasound, therapy - electrotherapy on the web
Download, page, ultrasound has been a part of clinical practice since sometime back in the 1950's, and remains a popular and evidenced intervention for a range of clinical problems. Shah and Farrow (2012) provide an insight into its current clinical popularity as does the widely cited paper by pope et al (1995). General (textbook) reviews and explanations can be found in Watson and young (2008) and Robertson et al (2006) amongst others. There are myriad therapy ultrasound machines available, from the small, portable devices, through to premier the multimodal machines which include ultrasound as one of the available options, examples are illustrated below. Ultrasound Energy, ultrasound (US) is a form. Mechanical energy, not electrical energy 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.

When energy is available, the body can heal itself. Laser therapy has been shown to stimulate the regeneration of bone, blood, the lining of blood vessels, cartilage, cochlear hair cells, central and peripheral nerve, and muscle. . Moreover, it has been documented to enhance the quality of healed tissue. Laser therapy may be an ideal treatment. It may not only effectively address many medical conditions but also has been widely reported to improve health and wellbeing as evidenced by a host of biological markers.

Laser therapy energizes living systems. Four well accepted effects in the scientific literature are: biostimulation / Tissue regeneration, reduction of Inflammation, analgesia. Enhanced Immune function / Antimicrobial, one important way in which laser therapy adds energy is through photon absorption by mitochondria. These tiny organelles which have been called the "powerhouses" of the cell, are found in most plants and animals. . Mitochondria are able to absorb laser light which then activates a series of reactions to increase and store more cellular energy in the form of adenosine triphosphate (ATP). By increasing energy available in this wash readily accessible form, laser light is able to greatly stimulate the biological function of cells, tissue, and systems and even raise overall vital energy throughout the individual.
