Low power laser irradiation, also referred to as low-level laser therapy (LLLT) or cold laser therapy, is a medical technique that involves the use of low-intensity laser light to stimulate cellular activity and promote tissue healing.
This therapy relies on the principle of photobiomodulation, wherein specific wavelengths of light are absorbed by the cells, triggering various biological responses. Low power lasers typically emit light in the visible or near-infrared range, which can penetrate into the body's tissues without generating heat or causing damage.
During low power laser irradiation, a handheld device emitting a laser beam is applied directly to the skin over the targeted area. The light energy is absorbed by the cells, leading to increased production of adenosine triphosphate (ATP), the primary energy source for cellular activities. This boost in ATP production enhances cellular metabolism, thereby promoting tissue repair, reducing inflammation, and relieving pain.
Low power laser irradiation has been used in various medical fields, including dermatology, physical therapy, and dentistry. It has been beneficial in treating conditions like wound healing, arthritis, musculoskeletal pain, and neuropathy.
Overall, low power laser irradiation is a non-invasive and safe therapeutic approach that utilizes low-intensity laser light to stimulate cellular activity and facilitate the healing process.
