Who started it? Electrodermal Screening (EDS) was founded by Dr. Reinhold Voll in the 1950's who developed a system called ElectroAcupunture by Voll - EAV
How does it work? In EDS screening acupuncture points on the meridians are used to assess the energetic health of organs & body system. The assessments are performed by measuring variations in skin characteristics with a probe as the client is energetically stimulated. The stimulation is provided by small test ampoules containing physical substances.
Computerised ElectroDermal screening (CEDS) is based on the same biofeedback principle as Electro Dermal Screening where changes in acupuncture point electrical characteristics are monitored to gain information about a client's energetic balance. CEDS differs in that digital test ampoules stored on a computer are used as opposed to physical test ampoules to perform a screening.
