How does laser theraphy work?

Low-level laser therapy operates based on the science of photochemistry. It involves using light energy, or photons, to modify chemical reactions in the body. Within the mitochondria, the cell's energy producer, receptors can absorb specific types of light, similar to how our body's receptors interact with medications. When a drug binds to its receptor, a reaction occurs within the cell. Similarly, exposing the body to specific light colors triggers a similar process. During treatment, this light enters the skin and is absorbed by mitochondria's receptors. This stimulation enhances energy production, biochemical reactions, protein synthesis, cell growth, blood and oxygen flow, and prevents cell death. By addressing multiple cellular issues with one therapeutic approach, this technique improves recovery and quality of life in wound healing.

The application of a line-generated beam delivered by a low-level laser device emits approximately 45 Bn photons every second. And although clothing material will demonstrate some degree of photon inhibition, the reaction at the cellular

level is truly a 1 to 1 reaction, requiring only one photon to excite one electron positioned within the photoreceptor. Although producing a clinical outcome necessitates more than one photon, clothing will not serve as a completely restrictive barrier therefore clothing will enable a clinically significant amount of photons to penetrate.

Low-level laser therapy delivers minimal energy, avoiding heat generation or vibrations within cells. It works on the sub-atomic level, influencing electrons around atoms, altering photoreceptor behavior and cell metabolism. Since the biochemical response to laser therapy primarily depends on the color of light and not the output energy, the sensation experienced is similar to what is felt when consuming a prescription medication: none. Low-level laser therapy boosts natural reactions, aiding struggling or overactive processes in injuries. Despite laser's association with tissue damage, this therapy operates like medication, affecting cell function without macroscopic sensations.

Low-level laser therapy, when combined with neuromusculoskeletal techniques, offers a multifaceted approach that can potentially address the root condition, providing results that last until tissue re-aggravation occurs. Clinical studies show immediate positive outcomes that can endure for weeks, but like other therapies, laser treatment necessitates multiple sessions to effectively resolve underlying causes of pain. Treating the injury site can significantly enhance blood and oxygen flow, reduce inflammation, and boost muscle activation and strength. However, unresolved injuries will eventually overwhelm these benefits, leading to pain recurrence. When coupled with preventive care, a series of low-level laser therapy sessions administered by a trained professional can achieve lasting results.
