This is the EMF Channel database of light therapy study doses. After getting the results, click to view more study details. Only successful studies are included. 99% of the studies here are on humans, not animals. This database is a work in progress. Many thanks to Vlad for his PBM database. When the data here references his work, the detail page includes a link to the PBM spreadsheet.
Changes in Brain Function and Structure After Self-Administered Home Photobiomodulation Treatment in a Concussion Case
One 23-year old traumatic brain injury patient complained of headaches, anxiety, and difficulty concentrating. He home-treated with a Vielight Neuro Duo. At an 8 week measurement he had increased brain volume, improved functional connectivity, increased cerebral perfusion, and neuropsychological improvements.
Transcranial Low-Level Laser Therapy May Improve Alertness and Awareness in Traumatic Brain Injured Subjects with Severe Disorders of Consciousness: a Case Series
Five traumatic brain injury patients with cognitive disabilities received transcranial 785 nm infrared laser 5 times per week for 6 weeks. They showed improved awareness and alertness, but two epileptic fits corresponded with treatment earlier that day. The fits also corresponded with concurrent antibiotic treatments.
Transcranial Photobiomodulation Therapy in the Cognitive Rehabilitation of Patients with Cranioencephalic Trauma
Improvements in immediate recall, information processing speed, verbal learning, PTSD stress reduction, depression reduction, reduced headache, improved sleep, and many more benefits.
Improved Cognitive Function After Transcranial, Light-Emitting Diode Treatments in Chronic, Traumatic Brain Injury: Two Case Reports
Improve cognition and memory in chronic TBI patients.
The Effects of Transcranial LED Therapy (TCLT) on Cerebral Blood Flow in the Elderly Women
Increase cerebral artery blood floow, decrease resistance.
Acute Effects of Near Infrared Light Therapy on Brain State in Healthy Subjects as Quantified by qEEG Measures
Decrease physical reaction times in concussion patients.
Psychological Benefits 2 and 4 Weeks After a Single Treatment With Near Infrared Light to the Forehead: A Pilot Study of 10 Patients With Major Depression and Anxiety
Decrease depression and anxiety in TBI patients.
Focal Increase in Cerebral Blood Flow After Treatment With Near-Infrared Light to the Forehead in a Patient in a Persistent Vegetative State
830 nm, 11.4 mW/cm^2, 1800 s, 2/day/73 days (146) improved blood flow and correlated with patient regaining cognition.
“The patient showed some improvement in his neurological condition by moving his left arm/hand to reach the tracheostomy tube, post-LED therapy.”
About the EMF Channel Light Dose Database
Many people purchase red light therapy or neuromuscular electrical stimulation devices without knowing optimal doses for the results they want to see. The right dose is especially key to light therapies, which have optimal windows of wavelength and energy delivered. Treatment doses outside of those windows will nullify results or harm the user. I took the results from successful EMF studies when these studies included:
- Photobiomodulation (Red Light Therapy, Blue Light Therapy, Low Level Light Therapy)
- Transcutaneous Electromagnetic Nerve Stimulation (TENS)
- Pulsed Electromagnetic Field (PEMF) Therapy
- Neuromuscular Electrical Stimulation (NMES)
Many studies do not report exact dose parameters they used. They are therefore not included here, even the study reported a therapeutic result.
