Here's a breakdown of the acceptance criteria and the study information based on the provided FDA 510(k) summary for the TENS & EMS Device (Model: FM-B2403A):

Please note: This document is a 510(k) summary focused on demonstrating substantial equivalence to a predicate device, not a typical clinical trial report for an AI-powered diagnostic/treatment device. Therefore, many of the typical questions regarding AI device performance studies (like test set provenance, expert qualifications, MRMC studies, standalone performance, training set details) are not applicable or explicitly stated in this type of submission. The "acceptance criteria" here refer to regulatory standards and comparative technical specifications, not predictive performance metrics.
