It is the application of a low power density laser (typically in the infrared to near infrared band) to a diseased tissue or monolayer of cells to elicit a non-destructive and non-thermal biological response for therapeutic purposes. Physical therapy means that it is safe and low cost and is suitable for long-term use. A plurality of animal experimental studies at home and abroad show that the LLLT treatment can activate osteoblasts, promote bone repair, enhance bone structure and increase bone density, and is expected to become a safe and effective intervention measure for middle-aged and elderly osteoporosis patients.
