Near Infrared Transcranial Treatment Improves Some Disorder of Consciousness Patients

Near Infrared Transcranial Treatment Improves Some Disorder of Consciousness Patients

Researchers compared “frontal near infrared laser stimulation (N-LT)” [photobiomodulation] with transcranial focused shock wave therapy (F-SWT) on patients with severe disorders of consciousness (DOC). Light therapy subjects received 10 minute infrared sessions of 0.1 mJ/mm2 five times per week for four weeks. A patient in the shock wave group suffered a focal seizure in week 3. Both groups had some members with significant improvements on the revised Coma Recovery Scale (r-CRS), but there were no significant differences between the groups.
Both Low and High Intensity Bright Light Treatment Reduce Epilepsy Correlated Anxiety and Depression

Both Low and High Intensity Bright Light Treatment Reduce Epilepsy Correlated Anxiety and Depression

Because depression and anxiety have “common psychiatric comorbidities in epilepsy,” researchers tested depression treatment with light on epileptic patients. 101 subjects had “medically intractable focal epilepsy.” Researchers treated 51 subjects with a high-intensity light box, and 50 subjects with a low-intensity light box. Each subject received one treatment per day. Only 58 subjects completed the trial. Depression and anxiety scores were significantly better for both groups. The study included no placebo controls.

Infrared Sinus Delivery the Most Efficient Choice to Stimulate the Brain

Infrared Sinus Delivery the Most Efficient Choice to Stimulate the Brain

Researchers tested 671 nm and 808 nm 1 mW/cm^2 laser photon delivery in a severed cadaver head. They compared sinus (transsphenoidal), oral, and head (transcranial) light delivery at both wavelengths. 808 delivered more energy than 671 to a 40 mm target inside the brain tissue. They found that sinus delivery delivered 20 times more photons than transcranial delivery. Comparing oral, sinus and head delivery, and comparing 671 nm to 808 nm delivered at the same power density, the 808 nm diode transferred the largest quantity of photons to the farthest parts of the brain.

Search the Photobiomodulation Database for studies on health conditions:

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.

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.
