About this episode

Dr. David Rosenblum discusses the mechanisms, clinical evidence, and applications of red light therapy for pain management.

PainExam Podcast Show Notes Red Light Therapy (Photobiomodulation) for Pain Evidence, Mechanisms, and Clinical Applications Host: Dr. David Rosenblum Red light therapy, also known as photobiomodulation (PBM) or low-level laser therapy (LLLT) , is an emerging non-invasive treatment modality increasingly used in pain medicine, rehabilitation, and regenerative medicine practices . In this episode of the PainExam Podcast , Dr. Rosenblum reviews the mechanisms, clinical evidence, indications, and safety considerations surrounding photobiomodulation therapy for pain. Red and near-infrared wavelengths stimulate mitochondrial activity, increase ATP production, reduce inflammatory mediators, and promote tissue healing. These physiologic effects may translate into analgesic benefits for a variety of musculoskeletal and neuropathic pain conditions. Clinical research suggests potential benefit in temporomandibular disorders, chronic neck pain, and inflammatory oral conditions , though results vary due to differences in dosing parameters and treatment protocols. Despite these limitations, PBM has a favorable safety profile and is increasingly being integrated into multimodal pain management…
