Laser Therapy is a non-invasive, pain-free treatment that is beneficial for a variety of ailments. Most commonly this treatment is seen in the form of low-level laser therapy (LLLT) but can be high-level laser therapy as well. LLLT uses red and near-infrared (NIR) light with wavelengths falling between 300 and 10,600 nm. Wavelength varies based on the treatment. Additionally, LLLT uses much lower energy and power densities than other forms of laser therapy, such as ablation, cutting, and thermal coagulation of tissue.
LLLT induces photobiomodulation, which uses light to alter biological activity and ultimately promote healing. The basic biological mechanism is thought to occur as the photons (light molecules) enter the target area and are absorbed by the mitochondria, which is the “powerhouse” of the cell and responsible for providing its energy. This activates numerous intracellular signaling pathways leading to cellular regeneration, which means damaged cells are naturally being fixed or replaced to promote healing. Ultimately, the possibilities of LLLT can be summarized as improvements of tissue metabolism and functionality.
With LLLT there have been no reported side effects or adverse events. Like many medical treatments, LLLT has been tested and used for both dogs and humans. In a 1997 canine study, researchers compared LLLT in humans and dogs in its ability to treat Benign Prostatic Hyperplasia (BPH), which is when the prostate gland becomes enlarged. Results showed the mean reduction in prostate volume to be 50% in dogs and 21% in human patients. These results suggest that LLLT benefits our wise woofs more than us, likely due to structural differences in our tissue.
While LLLT is a newer treatment, research is ever-evolving. Many studies have shown that using LLLT in combination with pain medications has actually resulted in a lower dosage of medication required (8). Additionally, dog patients have benefited from its use in combination with other alternative remedies, such as acupuncture, hydrotherapy, and more, often in a rehabilitation setting. LLLT continues to offer promising results for treating a number of tissue and pain-related ailments while being safe and noninvasive.
