The therapeutic claim of the Electronic Reactions of Abrams. Having assigned each disease a ‘vibratory rate,’ Abrams reversed the procedure and built the Oscilloclast to emit a chosen rate, said to neutralize the disease. The American Medical Association’s 1923 statement records that the Oscilloclast ‘is not for sale’ but leased under a contract not to open the sealed device. The evidentiary base was practitioner and patient testimonial; no controlled outcome data were published. The claim is refuted: the Scientific American committee (1923-1924) concluded the claims of ERA and ‘electronic practice in general, are not substantiated,’ and Nature’s 1925 engineering analysis found the apparatus functionless apart from a rocking magnetic interrupter passing about a micro-ampere of current. Classified testimonial because the cure claim rested entirely on uncontrolled report.
