What is Therapeutic Laser? How does it work?
Recent studies have shown that pure light of certain wavelengths in the red spectrum have powerful healing effects on tissues when applied locally. This kind of light and laser therapy (also called low-level light therapy or LLLT) can improve tissue repair, reduce inflammation and edema, and induce a pain-relieving effect wherever the beam has been applied.
The LED probe works by restoring efficient energy production (oxidative metabolism by mitochondria) to damaged or inflamed tissues. Areas of damage tend to produce free radicals and other toxic substances when they lose their ability to utilize oxygen properly. By restoring mitochondrial function, the light therapy effectively restores healing ability and causes inflammation to resolve quickly. Stem cells are also activated by light therapy, which further promote tissue healing and repair.
The smaller laser probe has a similar effect but is more intense and so it primarily deactivates pain fibers. Used over trigger points (areas of abnormal muscle tension and pain) and spinal segments, the laser causes immediate relief from pain and releases trigger point areas. Many patients become relaxed and sleepy during laser treatments, and LLLT works synergistically with acupuncture to relieve pain and promote healing.
