PBM SCIENCE
A careful introduction to the research model
Photobiomodulation, or PBM, is the preferred technical term used in research for approaches previously described as low-level laser therapy or low-level light therapy. The terminology reference is Anders, Lanzafame and Arany, 2015, PMID 25844681.
This page explains a limited research model. It does not predict whether cold laser therapy is appropriate for a particular person or what that person may experience.
This page provides general educational information and does not replace individual assessment or advice from an appropriate health professional. Individual responses vary.
How the research model is described
Research reviews propose that PBM involves light interacting with cellular photoacceptors and downstream signalling. This is a model described in laboratory and review literature, not a statement about what occurs in an individual patient. See de Freitas and Hamblin, 2016, PMID 28070154.
Research models also describe a biphasic dose response, a reminder that more exposure is not automatically better. This page does not provide dose tables or treatment protocols. See Huang et al., 2009, PMID 20011653.
These sources explain research models only. They do not establish personal suitability or predict an individual response.
What the science page can and cannot answer
Mechanism research and clinical evidence answer different questions. Evidence may differ by musculoskeletal condition, study design and protocol. A research model cannot decide whether a service is suitable for a particular person.
A consultation with Dr Sam Johnson (Chiropractor) can consider your history, the clinical question and whether cold laser therapy is worth discussing as one option. There are no lock-in plans. The decision is always yours.
All care is provided subject to clinical assessment and individual suitability. Individual responses to treatment vary.
