New Meta-Analysis Of Summarizes Benefits Of Red Light Therapy For Musculoskeletal Conditions

"In conclusion, low-intensity LASER and LED (PBMT) offers a non-invasive, safe, drug-free, and side-effect-free method for pain relief of both acute and chronic musculoskeletal conditions as well as fibromyalgia. Although there are other effective light-based therapies, these were not focused in this study. In our paper, we observed that, although there are several clinical studies demonstrating the analgesic effect of PBMT, some health conditions such as knee pain and postoperative pain after total hip replacement need to be further investigated due the limited research available. Some negative results were also found; however, these results are mostly due to the lack of previous optimization of the PBMT parameters used."
