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 strategies. Key Topics Covered \u2022 What is photobiomodulation therapy (PBM) \u2022 How red and near-infrared light interact with mitochondria \u2022 Mechanisms of analgesia and tissue repair \u2022 Evidence from clinical trials in TMD, neck pain, and oral inflammatory pain \u2022 The biphasic dose response (Arndt-Schulz law) \u2022 Safety profile and contraindications \u2022 How PBM may integrate with regenerative pain medicine Mechanism of Action Photobiomodulation works primarily through stimulation of mitochondrial chromophores, particularly cytochrome c oxidase. This leads to: \u2022 Increased ATP production \u2022 Modulation of inflammatory cytokines \u2022 Increased angiogenesis and tissue repair \u2022 Reduced oxidative stress These effects may improve pain, inflammation, and healing in certain musculoskeletal conditions.
