Concept of Laser Therapy in High and Low Intensity

-

High intensity laser therapy is based on the well-known principle of low-level laser therapy. High power and choice of the right wavelength allow for deep tissue penetration. HIL offers powerful and non-addictive form of pain management. 

Through a natural process of energy transfer (bio stimulation and photo mechanical effect) it speeds up healing and regeneration. HIL is particularly effective in treatment of sport injuries, e.g. muscle strain or joint distortion, and back pain caused by e.g. herniated disc or disorders in the cervical region causing neck pain.

Laser (acronym for Light Amplification by Stimulated Emission of Radiation) can be used as a therapeutic device which produces monochromatic (one specific wavelength), coherent (constant phase) and polarized (directional) light.The source of laser beam in therapeutic high-power lasers is typically a semiconductor diode capable of producing light of one specific wavelength (e.g. 1064nm).

The light generated by the diodes is then directed into an optical fiber, end of which is connected to the laser applicator. The beam is further processed by a series of lenses which ensure the right direction and diameter of the beam and consequently the spot.

Therapeutic lasers are defined by their power and wavelength. Wavelength is important as the ideal effects on human tissue are of light in the “therapeutic window” (approx. 650 – 1100 nm). 1064nm wavelength of the High Intensity Laser ensures a good ratio between penetration and absorption in the tissue. The amount of power a laser can safely deliver can reduce therapy time by more than a half.

Pain is a common problem that affects millions of people around the world. While there are many treatments available for pain relief, not all of them are effective, and some may have negative side effects. Ear acupuncture laser therapy is a safe and effective alternative to traditional pain relief methods. This treatment has been used for centuries in Traditional Chinese Medicine and is gaining popularity in the Western world due to its numerous benefits. Here are some of the benefits of ear acupuncture laser therapy for pain management: ●      Natural pain relief: Ear acupuncture laser therapy is a natural and non-invasive method of pain relief. It does not involve the use of drugs or surgery, making it a safer option for many people. ●      Effective for chronic pain: Ear acupuncture laser therapy has been found to be effective in treating chronic pain, including headaches, back pain, and arthritis. It can also be used to manage pain associated with cancer treatment.   ●

How Laser Therapy is Helpful in Medical Science

Laser therapies are medical treatments that use focused light. Unlike most light sources, light from a laser (which stands for light amplification by stimulated emission of radiation) is tuned to specific wavelengths. This allows it to be focused into powerful beams. Laser light is so intense that it can be used to shape diamonds or cut steel. In medicine, lasers allow surgeons to work at high levels of precision by focusing on a small area, damaging less of the surrounding tissue. If we have laser therapy, we may experience less pain, swelling, and scarring than with traditional surgery. However, laser therapy can be expensive and require repeated treatments. Laser therapy device may be used to treat the following: Ø shrink or destroy tumors, polyps, or precancerous growths Ø   relieve symptoms of cancer Ø   remove kidney stones Ø   remove part of the prostate Ø   repair a detached retina Ø   improve vision Ø   treat hair loss resulting from alopecia or aging Ø   treat pain, incl
