This video discusses the use of lasers in physical therapy and how to correctly adjust the power and dosage. It explains that, depending on the area being treated, a laser may emit less power the larger the area it covers. This means that the covered area will receive less energy than the original focal point, leading to decreased effectiveness. The video also discusses the two main types of laser therapy: pulsed and continuous. With pulsed therapy, the pulse frequency can be set at any percentage, but it is always 50%. The power of the laser will be reduced in half with every pulse.

00:00:00 The video discusses the use of laser therapy and its dosage. First, the term "laser" is explained as a portmanteau of the words "light amplification" and "stimulated emission of radiation." The term "laser" is then used with its accentuated meaning, and either term is acceptable. Next, laser therapy and its dosage is discussed, with particular emphasis on the use of different frequencies of light. Finally, the uses of laser therapy are detailed, with particular emphasis on the use of lasers in physical therapy.
00:05:00 The laser is a type of radiation that is not ionizing and has a longer wavelength than the cavities that can exist between atomic particles. This allows the light to be absorbed by the first few layers of skin, then transported deeper into the body. Here we have infra-red lasers, which are similar to typical lightbulbs, but in a closed box. These lasers use infra-red radiation in the near-ultraviolet range, which is closer to the light wavelength than other types of lasers. The laser can be used for various medical treatments, including radiation therapy for cancer. It consists of a very powerful light beam that can cut metal. It also has other applications, such as recording discs in a computer. When the laser is focused on an object, it burns through the object, leaving a "mark" that can be seen with an ultrasound or MRI. The laser's energy is very concentrated in a point, and this is what allows the laser to create a laser beam. The laser consists of concentrating a very powerful light beam in one point.
00:10:00 In this video, laser therapy is discussed in relation to physical therapy. The laser power and frequency ranges that are most commonly used are discussed, as well as the characteristics of a laser that make it suitable for use in physical therapy. Coherence and monocromatism are also discussed. The power range that is most commonly used in physical therapy is 1-10, but 1-10 is not the only range that is available. There are also systems that can be set to regulate the power to 1-5 or 1-10.
00:15:00 In this video, the different types of laser therapy and their dosages are discussed. It is explained that, while a 1- to 10 scale is often used to measure the intensity of a pain-relieving treatment, this is not always the case when it comes to laser therapy. For example, a 5 on a 1- to 10 scale might be equivalent to a very light breeze, while a 10 on the scale would be equivalent to a hurricane. It is also explained that, in some cases, the patient may not be able to accurately quantify the intensity of the treatment. In these cases, a system that measures in "vatio" (or "vatios" in Spanish) may be more appropriate. This system uses the Latin phrase "potenza in vatios," which means "the amount of work or power in vatios." It is explained that, in order to use this system, the therapist must first understand the concepts of wattage and voltage. Next, they must calculate the theoretical maximum power that the laser can generate. Finally, they must use this information to select an appropriate intensity level for the patient.
00:20:00 This video discusses the importance of laser power and how to correctly adjust it for treatment. It explains that, depending on the area being treated, a laser may emit less power the larger the area it covers. This means that the covered area will receive less energy than the original focal point, leading to decreased effectiveness. The concepts of power received and power emitted are very important to keep in mind when using a machine and adjusting its settings. This example illustrates how a child could measure how much light is emitted from a light source by holding it up to the sun and measuring the angle at which it reaches everyone. The light emitted is then concentrated into a single beam when it is directed at a small target. In the case of laser therapy, the beam is so powerful that it can penetrate what would normally be a protective shield. The amount of time a session should last is the same regardless of the power used.
00:25:00 This video discusses the use of lasers in physical therapy and its two main types: pulsed and continuous. It explains that when using too much power, we end up treating a large area even if it is small, while using a smaller area results in treatment being completed earlier if it is treated continuously. If we have a small area to treat, we will end up completing treatment earlier now if the area is wide. Laser therapy is similar in its effect to the area treated being wide even if it is small. The time for a session must be different for each area treated, depending on how long the laser beam is kept on the patient. For example, if the laser is kept on continuously, the power will be reduced, which would result in a decrease in power to the patient. To calculate power delivered, we need to know the laser beam characteristics, such as its length and width. Knowing how the laser beam behaves is important, as we might put ourselves in danger if we don't understand how it works. There are other examples such as a topographical map that can be used to measure the power delivered by a laser. In this case, the laser beam is projected onto a paper map and the amount of power delivered at two different distances from the projector is measured
00:30:00 Laser therapy is a type of therapy that uses a beam of light to treat various conditions. In this video, red and infrared lasers are discussed, and CO2 lasers are also mentioned. These lasers work constantly and can be pulsed, with a frequency that can be controlled. Gas-powered lasers usually work continuously, but they can be pulsed. The difference between these types of lasers is that gas-powered lasers produce a lot of heat, which can quickly burn the patient. There are also laser therapy machines that use high-power lasers that are used in surgery. These lasers can generate many joules of energy in a very small amount of time, and can cause burns. In this video, we talk about the types of lasers and how to use them safely. Finally, we discuss the risk of losing time by getting lost in the technology and forgetting the patient.
00:35:00 The video discusses the use of laser therapy in physical therapy and its two main types of dosing: point-by-point and diffuse. Point-by-point laser therapy is typically done with a fiber optic head at the beginning, but it is becoming less common because the laser emits a concentrated beam with a point that remains on the left side. This method can be applied in a regular, timed way with a diode-based head. With a refracted point, which is still common, the head still emits a concentrated beam, and the surface treated or the patient's body surface is no smaller than 1 cm square. The energy concentrated in a small area can cause tissue burns. With a fiber-optic head, the distance between the user and the treated area should not be less than 1 cm square in order to avoid concentrating too much energy in a small area and start causing risks of burns. When applying the laser, it is important to take care also to position the head so that it is as perpendicular to the treated area as possible in order to avoid reflection and radiation effects. Too much energy can be concentrated in a small area if the surface is very small. When using the laser, it is also important to avoid placing the head too close to the
00:40:00 In this video, an author explains how laser therapy works and how to adjust the dosage to best suit the patient. The author also discusses the importance of having a long boquilla and a greater distance to reduce the power of the patient. He mentions the term "seda de caña" (lit. "cane's thirst"), which is now falling out of use, and instead refers to laser therapy using the names "helio, neón, and león." The author talks about laser therapy machines that have a lot of power, such as CO2 lasers. He also discusses point and area barrios, which use laser lines and points to cover an area. He shows an example of a patient being treated with a laser and demonstrates how the line moves across the patient, revealing the area covered. He then shows an example of a machine that emits a continuous beam of light and uses a diode to emit a red light. He shows how this red light can be used to guide a laser beam to the target area. In the end, he discusses the importance of selecting the right laser and adjusting the dosage to best suit the patient.
00:45:00 This video demonstrates the powerful effects of laser therapy on physical therapy and its dosificat ion. It features a demonstration of how a laser can be used to treat tissue damage, with particular focus on the fingers. The black tape test is also shown, in which a person's hand is illuminated with a laser and then the light is passed through a black tape. The person's hand does not pass the black tape, but when the tape is illuminated with a blue laser, the black tape passes through it. The blue laser has a much lower power than the red and yellow lasers, so it is not capable of damaging tissue as severely. The video then discusses how laser therapy is dosed and how the power of the laser can be adjusted. It goes on to say that laser therapy is becoming more popular, as it has a high therapeutic effect with a low risk of side effects. A machine that generates a high power laser is shown, and it is explained that it generates 10 julios per second. The video then goes on to explain how this is translated into watts and how it is measured. It concludes with a demonstration of how to take a measurement with a Watts meter.
00:50:00 This YouTube video provides a tutorial on how to use a laser to treat physical therapy and exercise patients. The laser produces two beams and is capable of lasting 500 seconds. The total number of julios generated by the laser can be calculated by multiplying 500 seconds by 2 and then dividing by the number of square meters the laser was applied to. The julios total for a given area can be calculated by multiplying 35 julios per square meter by the number of square meters in the treated area.
00:55:00 This video discusses laser therapy, its uses in physical therapy, and dosage calculation. The surface area in square meters is equal to July divided by centimeter, and the square of the surface area in centimeter is the dose. In this case, the dose is in millimeters squared, or multiplied by 0.5 to get the actual dose in millimeters. There are two basic types of laser therapy: continuous and pulsed. With continuous therapy, the pulse frequency is set at 50%. With pulsed therapy, the pulse frequency can be set at any percentage, but it is always 50%. The power of the laser will be reduced in half with every pulse, but there are other laser manufacturers that use a fixed frequency and no reduction in power. The dosage will be calculated according to the following equation: the effective dose is equal to the average power over the period of the pulse multiplied by the surface area treated. In this video, the time in seconds is divided by the number of pulses in the period and the result is multiplied by 0.5 to get the actual dose in millimeters.

This video discusses the use of laser therapy in physical therapy and its two dosage forms. The first part of the video covers the basics of laser therapy, including its applications, how it works, and the various types of lasers available. The second part of the video focuses on the use of lasers in physical therapy, discussing the changes that have been made to the beauty cycle in order to accommodate laser therapy. Finally, the video discusses the use of high-power lasers in physical therapy and the risks associated with their use.

01:00:00 In this video, Vatios explains how laser therapy works and how it is dosed. He also discusses the importance of knowing the power and frequency of the laser being used, as well as the distance between the patient and the laser. He demonstrates how to calculate the power and frequency of a laser being used. Finally, he discusses how to perform laser therapy sessions and how to dose the laser.
01:05:00 In this video, the author discusses the importance of laser therapy and its dosificaton. He explains that the needs of the technique must be greater than what is offered by the manufacturers of laser therapy devices. It is important that we control and dominate the technique so that we know what we are buying and know what we are using. Lasers are effective, but not always effective. The author answers a question and then the teacher of the technique, señor Eduardo Candela, speaks. Jacqueline asks a question about the frequency of laser therapy. The author explains that the ratio of pulse to pause time is important. Jacqueline asks about a different frequency system. The author offers a mathematical system to calculate the effective power and useful power. He then suggests that the frequency is not important, and that the ratio of pulse to pause time is more important.

01:15:00 These lasers comprise two types of lasers currently in use: thermal and thermal. The main difference between the two is that thermal lasers emit heat, which can be useful in certain treatments involving infrared light, such as thermography. However, the main concern is that if we work with infrared light, we are applying heat. This heat then causes the cells to work more energetically, which can result in a faster metabolism and fever. Therefore, it is important to first determine the type of laser being used, thermal or thermal, as this will largely determine the level of heat delivered. In the end, it is not actually perceivable as heat, only heating. Therefore, I leave this topic open for further discussion. We will return to it later.
