In addition, the treatment areas are different. The Personal Laser L200 is primarily used for wounds, skin conditions, tinnitus, and arthritis. The L400, on the other hand, is used for muscle, tendon, and joint problems, as well as for the supportive treatment of scar tissue.\u003cbr\u003e\u003cbr\u003e The device is the perfect choice for those in a hurry or those with a deeper injury.

LED devices are often referred to as laser therapy devices, but they differ in several respects from \"real\" lasers, such as the Personal Laser L400.\u003cbr\u003e\u003cbr\u003e LED stands for light-emitting diode. A diode that emits light when current flows through it, often in bright colors. LASER, on the other hand, stands for \"light amplification by stimulation of emitted radiation.\" A light source is amplified in a medium and emitted in a very specific way, described below.\u003cbr\u003e \u003cbr\u003eReal lasers are monochromatic. This means that the light produced by a laser has a single, very specific wavelength. LEDs are also capable of producing monochromatic or nearly monochromatic light. However, diode lasers like the L400 concentrate their entire power into a small spot. Laser light is coherent, and coherent light can be transmitted over much greater distances than incoherent light.\u003cbr\u003e\u003cbr\u003e LEDs distribute their power over a larger area, but without reaching the depth of tissue penetration that is possible with a real laser.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eCalculation of laser dosage and energy density\u003c\/strong\u003e\u003cbr\u003e To calculate the dose of energy density, the units must be expressed in standard units. The power of a laser device is measured in watts, with one milliwatt equal to 1\/1000 of a watt.\u003cbr\u003e \u003cbr\u003eBefore performing dose calculations, the laser's power can also be converted into watts. For the L400, this is 0.4 watts. Power is the rate of energy delivery over time, meaning that power, energy, and time are interrelated.\u003cbr\u003e\u003cbr\u003e The energy emitted by a laser can be calculated by multiplying the laser power by the treatment duration. For the L400, for example, this is 3 minutes.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003eEnergy (delivered dose) = power x time = 0.4W x 180s = 72 joules (J)\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e An important criterion for the treatment is energy density.

This eliminates a large portion of the reflected energy loss from the skin, allowing more energy to penetrate the tissue.\u003cbr\u003e When light pressure is applied to the skin with the L400 laser, part of the blood supply to that area can be suppressed, thereby reducing the absorption of energy by the hemoglobin and oxyhemoglobin in the blood. \u003cbr\u003e• If the laser is used in physiotherapy practice, the patient record should include clinical progress, the total amount of joules delivered to each area, the treatment technique used and a plan for the next session.\u003cbr\u003e\u003cbr\u003e \u003cstrong\u003ePoint treatment technique\u003c\/strong\u003e \u003cbr\u003e\u003cimg align=\"right\" alt=\"Laser spot treatment technique\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0890\/0372\/1035\/files\/laser-punktbehandlung.jpg?v=1733541692\" style=\"width: 100%; height: auto; max-width: 202px;\"\u003e The point treatment is performed by moving the laser from point to point, as shown in the image, with a distance of 1-2 cm between each point.
