The provided text is a 510(k) summary for a TENS and Muscle Stimulator device. It details the device's technical specifications and compares them to two predicate devices to demonstrate substantial equivalence, rather than providing a study proving a device meets specific acceptance criteria.
As such, the document does not contain information about the acceptance criteria and the study that proves the device meets those criteria in the way typically required for AI/ML-based medical devices or diagnostic devices that require performance evaluation against clinical ground truth.
The provided text focuses on electrical safety and performance standards for a TENS and Muscle Stimulator, which are typically assessed through bench testing, not clinical studies with "acceptance criteria" related to diagnostic accuracy, sensitivity, specificity, etc., or human reader improvement with AI assistance.
Therefore, I cannot extract the requested information regarding:
- A table of acceptance criteria and the reported device performance: This document lists technical specifications and compliance with electrical safety standards, not diagnostic performance metrics.
- Sample size used for the test set and the data provenance: Not applicable here, as it's not a performance study on a test set of patient data.
- Number of experts used to establish the ground truth and qualifications: Not applicable.
- Adjudication method for the test set: Not applicable.
- MRMC comparative effectiveness study or effect size: Not applicable.
- Standalone (algorithm only) performance: Not applicable.
- Type of ground truth used: Not applicable.
- Sample size for the training set: Not applicable (not an AI/ML device in the context of this document).
- How the ground truth for the training set was established: Not applicable.
What the document does provide in terms of "acceptance":
The document demonstrates that the new device meets electrical safety and performance standards the FDA considers essential for this type of device to be "substantially equivalent" to legally marketed predicate devices. The "acceptance criteria" in this context are primarily the successful completion of tests according to the following voluntary standards:
- ANSI AAMI ES60601-1: 2005/(R)2012 And A1:2012, C1:2009/(R)2012 And A2:2010/(R)2012 (Consolidated Text) Medical Electrical Equipment - Part 1: General Requirements For Basic Safety And Essential Performance (IEC 60601-1:2005, MOD): General safety requirements.
- IEC 60601-2-10 Edition 2.1 2016-04, Medical Electrical Equipment - Part 2-10: Particular Requirements For The Basic Safety And Essential Performance Of Nerve And Muscle Stimulators: Specific safety and performance requirements for nerve and muscle stimulators.
- ANSI AAMI IEC 60601-1-2:2014, Medical Electrical Equipment -- Part 1-2: General Requirements For Basic Safety And Essential Performance -- Collateral Standard: Electromagnetic Disturbances --Requirements And Tests: Requirements for electromagnetic compatibility.
- IEC 62133-2 Edition1.0 2017-02 Secondary Cells And Batteries Containing Alkaline Or Other Non-Acid Electrolytes - Safety Requirements For Portable Sealed Secondary Cells, And For Batteries Made From Them, For Use In Portable Applications - Part 2: Lithium Systems: Battery safety.
- IEC 60601-1-11 Edition 2.0 2015-01, Medical Electrical Equipment - Part 1-11: General Requirements For Basic Safety And Essential Performance - Collateral Standard: Requirements For Medical Electrical Equipment And Medical Electrical Systems Used In The Home Healthcare Environment: Requirements for home healthcare use.
The statement "The conclusion drawn from the safety testing is that the new devices are substantially equivalent to the predicate devices. Furthermore, the new devices comply with the recognized standards and perform its intended tasks as well as the legally marketed predicate devices." serves as the proof of compliance with these "acceptance criteria" (i.e., meeting the requirements of the cited standards).

The application area of electrode pads must be larger than 12cm². The electrode pads are provided by Shenzhen Mailuokang Technology Co., Ltd. with 510(k) cleared Number K152815.
This FDA 510(k) summary describes the MHD TENS device and establishes its substantial equivalence to a predicate device (K143268). The provided document does not contain information about a study proving the device meets acceptance criteria in the manner typically expected for AI/ML device performance (e.g., clinical study with human readers, ground truth establishment, etc.). This is because the MHD TENS is a physical electrical stimulation device, not an AI/ML diagnostic or therapeutic system.
Instead, the "acceptance criteria" for a device like the MHD TENS are compliance with recognized electrical safety and performance standards, and comparison with a legally marketed predicate device to demonstrate substantial equivalence. The "study" proving it meets these "acceptance criteria" consists of engineering tests and comparisons to the predicate.
Here's the information extracted and formatted, noting where AI/ML-specific criteria are not applicable:
