This episode reviews a 2026 pilot study evaluating the effects of photobiomodulation therapy (PBMT) on inflammatory and cartilage biomarkers in patients with advanced knee osteoarthritis. We discuss the biologic rationale for PBMT, changes in serum and synovial fluid cytokines, and whether these findings move PBMT closer to being considered a disease-modifying intervention rather than simply a symptomatic treatment.  https://pmc.ncbi.nlm.nih.gov/articles/PMC12972950/#sec1-2 Ferreira, Nathalia Lopes et al. “Photobiomodulation Therapy Modulates Inflammatory and Cartilage Biomarkers in Patients with Knee Osteoarthritis: A Pilot Case Series.” Journal of orthopaedic case reports vol. 16,3 (2026): 315-321. doi:10.13107/jocr.2026.v16.i03.6980 YouTube ChannelView the many other episodes and videos available here Laser Therapy Institute Further Resources: Success with Laser Therapy Flowchart & Checklist InfographicCheck out these FREE Provider ResourcesRead about laser research on the LTI BlogLearn more about what we offer on the LTI websiteFind out how you can Customize your LTI experience

Joining us today is Tommy Mulhern — Physician Associate, Marine Corps Veteran, and emerging voice in the field of psychedelic-assisted therapy. Tommy and Dr. Rountree served together in the Marines and recently reconnected over their shared interest in advancing healthcare. After years working in conventional medical roles, Tommy became increasingly aware of healthcare's shortcomings in addressing mental and emotional suffering. Guided by his own healing journey and work with ketamine and psilocybin-assisted therapy, he now devotes himself to bridging conventional medicine and natural medicines — helping individuals access deeper, more complete healing while contributing to the growing movement advancing safe and accessible psychedelic care. As discussed in the podcast, screening and post-experience integration are essential for successful treatment. Tommy provides information and clinical screening for patients seeking psychedelic-assisted therapy to improve outcomes for patients with PTSD, depression, and addiction.

What's going on with this "new" laser wavelength of 1064nm? Find out how this wavelength compares to more traditional PBM wavelengths like 830nm, as well as the reasons to use 1064nm in this research review! "There are a few reasons for utilizing a 1064 nm laser. First, the absorption of water at 1064 nm is relatively weak, lower than that at 950-1000 nm and comparable to that at 900 nm (see the following figure). Second, light at this wavelength can penetrate deeper in tissue than other wavelengths shorter than 1000 nm used for LLLT because of lower light scattering. For example, 1064 nm light penetrates the human hand better than 660 nm or 980 nm, and comparable to 830 nm [data of Karl H. Norris, from The Science of Photobiology (KC Smith, ed., Plenum Press, 1977; p. 400)]. Since our future application of LLLT targets on transcranial laser stimulation or photobiomodulation, it is definitely beneficial if the light can penetrate deeper in tissue. Third, the wavelength 1064 nm is still at the upper absorption band of the redox state of CCO 1 meaning that a 1064 nm laser will be absorbed to stimulate the reduction-oxidation reaction of CCO, as we needed for this study. Fourth, this project wished to examine whether the 1064-nm laser was able to stimulate or generate a reasonable amount of changes in HbO and CCO concentrations, even using a non-optimal laser wavelength. For future studies, given the absorption spectra of water and redox state of CCO, it might be optimal to use a laser near the absorption peak of CCO (e.g., at ~830 nm) where water absorption is also lower than that at 1064 nm."
