# ELF-007 — Symptoms during blinded electric field transitions

Why this matters
Symptoms deserve careful investigation even when they are difficult to explain. This blinded challenge recorded one person's responses to a power-frequency electric field. Its value is a testable individual observation; it does not tell us how common such responses are or establish a diagnosis for other people.

Topic: Symptoms and measured exposure

Verification Group: Original text reviewed

Record Role: Original text reviewed

Featured: True

Exposure: 60 Hz electric field, average over head 300 V/m; repeated 100-second challenge intervals.

Design: Clinical case and controlled provocation; n=1; accepted manuscript methods inspected.

Finding: One participant reported symptoms in all 10 pulsed-field intervals, versus mild symptoms in five and none in five sham intervals. A separate behavioural task found no above-chance conscious field identification.

Boundary: Individual response, not prevalence or general RF causation. Continuous versus pulsed conditions and symptom scoring must remain distinct.

Related: Different field regime from RF-013.

Protection Question: Is this person's symptom response reproducible under comparable blinded conditions? A controlled individual observation is worth understanding without turning it into a prevalence estimate, general RF effect or diagnostic test.

Access: Original accepted manuscript methods and results inspected

Locator: Accepted manuscript Tables 2-5; symptoms and field-identification tasks are separate
