tested — not confirmed— Real instrument/substrate; the diagnostic or therapeutic interpretation failed testing; a correct reinterpretation remains open (§0.1-B).
Diagnostic claim · Tested — not confirmed · grade F
Blind-tested and not confirmed — the diagnostic doctrine.
Therapeutic claim · Insufficient evidence / under study · grade E
Unstudied — the therapeutic claim, insufficient evidence.
A skin-electrical measurement device whose diagnostic doctrine descends from EAV/Voll and radionics. Two claims, two verdicts: the diagnostic claim was tested and not confirmed (it principally registers skin resistance, which does not track health status); the therapeutic claim is unstudied. Filed beside EAV/Voll and Vega for substrate consistency, not doctrinal kinship.
Enforcement & provenance — Enforcement & provenance (a SEPARATE line from the evidence tier, per display rule): Nelson's company registered with the FDA in 1989 as a biofeedback (stress-relief) manufacturer only; in 1992 the FDA held diagnostic/treatment use outside that permission and a software recall covered the 139 distributed units; Nelson was indicted on nine felony fraud counts in 1996 and left the US, continuing manufacture from Budapest; after a 2007 Seattle Times investigation the FDA revoked the manufacturer registration and barred importation in January 2008. These are enforcement/provenance facts and do NOT move the evidence tier.
Origin & lineage
William C. Nelson (QXCI / EPFX / SCIO); descendant of EAV/Voll and Abrams radionics.
Claimed mechanism
Measures skin electrical parameters and reads them as a whole-body diagnosis, then 'balances' the body with returned frequencies.
Plausibility
Implausible as a diagnosis; the substrate (skin electrical measurement) is real.
Evidence — grade F
Dual verdict. DIAGNOSTIC: tested and not confirmed — the blind-testing record is the EAV/EDS literature carried on the adjacent EAV/Voll and Vega rows; the device principally registers skin resistance, which does not track health status (grade F). THERAPEUTIC: unstudied, insufficient evidence (grade E).
Skin electrical measurement is real instrumentation — the same substrate carried on the EAV/Voll and Vega rows.
Set aside — claim
The whole-body diagnosis from skin-resistance readings was tested and not confirmed; the therapeutic 'balancing' is unstudied. Enforcement history is a fact line, not an evidence verdict.
Regulatory status by jurisdiction
Registration or clearance is a market-access fact, never proof of efficacy.
US — FDA
1989 biofeedback (stress-relief) registration only; revoked and import-barred Jan 2008; diagnostic/treatment use never permitted.
