Study of the Effects of Photobiomodulation in Patients With Osteoarthritis

Study Description

Brief summary:

PhotoBioModulation (PBM) is a mature science with therapeutic efficacy in humans and animals, and with excellent results in different medical specialties without side effects. However there are gaps that prevent adoption on a large scale. Recent research developed by our group and partners allowed us to understand the mechanisms of action of PBM, from Molecular Physics through Biochemistry and with consequent clinical validation, with precise, replicable and personalized therapeutic results. These findings have led to treatments for many kinds of pains with industrial predictability and accuracy, phenotypic adequacy technologies that are encapsulated, prescribed, and applied. Photobiomodulation applications cover treatments for pain, inflammation, tissue regeneration, healing, immune system activation, all of which are essential characteristics for osteoarthritis therapy. Our idea is to formulate great challenges of Photobiomodulation as a solution to osteoarthritis as follows: 1) Make PBM-based therapies as predictable as drug-based therapies; this is possible with precise dose calculation performed by our team; 2) Map the biochemical and molecular effects of PBM, including those related to gene expression; 3) Unify PBM theory by synthesizing and giving meaning to the millions of PBM data associated with osteoarthritis and correlating with clinical study to be performed under this thematic project. Overcoming these challenges, PBM will become a complementary (or supplementary) alternative to medications, physiotherapy and surgical procedures for the treatment of osteoarthritis.
