The thought that laser therapy produces light energy can minimize inflammation, pain, promote healing of the tissues that are damaged and cause nerve regeneration may appear far-fetched. Nevertheless, scientific study shows that these effects are possible and occur. The extent to which they happen depends on power and wavelength.
The two factors power and wavelength determine the ability of the laser so that it can enter into the body. The laser penetrates your body like x- rays, as you are in and over 800 nanometers in the effect of wavelength, to obtain depth requirement of considerable energy or power, is needed. Many devices are dependable and can be of great help and used for laser therapy unit for physiotherapy and utilized to promote pain relieving, healing effect and as an anti-inflammatory.
Two classes or types employed in physical therapy
In physical therapy, two types of laser are utilized, i.e., class 3 and class 4. The former that is class 3 lasers are said to be not more than 500 milliwatts (MW) whereas class 4 are more than 500 MW. Class 3 lasers are cold lasers (LLLT), and class 4 are high power laser (HPLT).
Most of the neuromusculoskeletal conditions are responsive to a higher dose and higher power in a better way which can be brought about by time and power output. You are going to attain the best results by way of a laser having 30 watts of power or can be more. 1800 joules are produced by 10 minutes of treatment by which are achieved healing, anti-inflammatory, and pain relieving effect.
After receiving 1 or 2 treatments patients feel better, though 5 or more can be required to solve the problem. Treatment depends on the severity, and more chronic injury requires more treatment.
Advantages associated with High-Power Laser Therapy
Pain Relief
By use of a laser, nerve sensitivity is decreased by bringing about a reduction in bradykinin which elicits pain chemicals. Using it makes ion channels normal (cellular gatekeepers) and stimulates endorphins that are natural painkillers of the body and also enkephalins that give the effect of analgesic. On some nerve fibers, it acts as a pain blocker. In home, you can use portable laser therapy unit
Anti-inflammatory and Healing
By laser ATP (Adenosine triphosphate) is enhanced which can be said to be stored energy. With the increase in energy repair process concerned with cells gets enhanced. The laser causes dilation of veins and arteries about the injury by which cellular debris is removed and enhances oxygen and nutrition. Moreover, there is an increase in white blood cells which facilitates quick repair process. There is a reduction in some molecules that are responsible for increasing inflammation also a few beneficial antioxidants get increased.
