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.

Light Dose Parameters
Term
Parameter
Time
Seconds
Power
milliwatts (mW) or Watts (W)
Total Dose Energy
joules (J) = power x time = Watts x seconds
Wavelength
nanometers
Frequency
Hertz (Hz)
Spot Size
cm(2) (centimeters squared)
Duty Cycle
percentage of time light source is on during one cycle
Power Density (or Intensity)
Watts per centimeters squared (W/cm(2) = power / probe size
Energy Density (Fluence)
jules per centimeters square (J/cm(2)) = total energy delivered by the probe size
