Photobiomodulation (PBM) — Research Protocol
⚠️ RESEARCH SUMMARY — NOT A TREATMENT PROTOCOL. Discuss all findings with your healthcare provider.
Published research on transcranial and systemic photobiomodulation has investigated specific wavelengths (red 630-670nm, near-infrared 810-850nm) for their effects on mitochondrial function. Dosimetry parameters vary across published studies. This page summarizes published research protocols. It is not a guide for self-treatment. Discuss any treatment decisions with your physician.
Research Dosing (from Published Studies)
| Context | Dose | Route | Frequency | Notes |
|---|---|---|---|---|
| Transcranial (neurodegeneration research) | Dosing regimens in published literature vary — consult the cited studies for details | Transcranial LED/laser | See cited trials | Published research has investigated 810nm wavelength for brain applications. Some studies have investigated pulsed delivery. See cited trials for specific parameters investigated. |
| Intranasal PBM (pilot studies) | Dosing regimens in published literature vary — consult the cited studies for details | Intranasal clip | See cited studies | Pilot studies have investigated intranasal approaches targeting the olfactory pathway. See cited studies for specific parameters. |
| Systemic/whole-body research | Dosing regimens in published literature vary — consult the cited studies for details | LED panel (full body) | See cited studies | Research has investigated whole-body approaches for broader anti-inflammatory effects. Various wavelength combinations have been studied. See cited studies for details. |
Pharmacokinetics
Photons at 810nm penetrate 3-4cm through skull and tissue. Absorbed by cytochrome c oxidase (CcO) in mitochondrial Complex IV. Effects are dose-dependent with a biphasic (hormetic) response — too little is ineffective, too much is inhibitory (Arndt-Schulz curve).
Safety Profile
Excellent safety profile. No reported serious adverse events in clinical studies. Mild: temporary headache, visual disturbance (if eyes exposed). No thermal injury at recommended doses. FDA-cleared devices available for pain and wound healing.
Contraindications
- Direct eye exposure (wear appropriate eye protection)
- Over active malignancy (theoretical concern — may promote tumor growth)
- Photosensitizing medications without dose adjustment
- Over thyroid in hyperthyroid patients
Monitoring Parameters
- Cognitive assessment tools (MoCA, MMSE) for neurological applications
- Motor function scales (UPDRS) for Parkinson's
- Session dosimetry logging (J/cm², wavelength, duration)
- Skin assessment for any photosensitivity reactions
