I apologize, but this document does not contain the information you requested regarding acceptance criteria and the comprehensive study details.

The document is an FDA 510(k) clearance letter for a "Pelvic Floor Stimulator (Intrelief PFE)." It confirms that the device is substantially equivalent to legally marketed predicate devices and outlines the regulatory requirements the manufacturer must adhere to.

However, it does not include:

• A table of acceptance criteria and reported device performance.
• Details about sample sizes for test or training sets.
• Information on data provenance (country of origin, retrospective/prospective).
• Number or qualifications of experts used for ground truth.
• Adjudication methods.
• Results of a multi-reader multi-case (MRMC) comparative effectiveness study or related effect sizes.
• Results of a standalone (algorithm-only) performance study.
• The type of ground truth used (e.g., expert consensus, pathology, outcomes data).
• How ground truth for any training set was established.

This letter focuses on the regulatory clearance process rather than providing a detailed technical or clinical study report.

Intrelief provides transcutaneous electrical nerve stimulation (TENS) and electrical muscle stimulation (EMS) device for the respective indications listed below.

TENS: The device is designed to be used for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, neck, upper extremities (arm), lower extremities (leg), abdomen and bottom due to strain from exercise or normal household work activities.

EMS: The device is designed to be used to stimulate healthy muscles in order to improve and facilitate muscle performance.

The provided text is an FDA 510(k) clearance letter for the Intrelief device, indicating its substantial equivalence to predicate devices for use as a Transcutaneous Electrical Nerve Stimulator (TENS) and Electrical Muscle Stimulator (EMS) for pain relief and muscle performance, respectively.

This document does not contain any information regarding:

• Acceptance criteria for device performance.
• Study details (sample size, data provenance, expert qualifications, ground truth establishment, adjudication methods, MRMC studies, standalone performance) that would prove the device meets specific performance criteria.

Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets the acceptance criteria based on the provided text. The FDA 510(k) clearance process primarily evaluates substantial equivalence to existing legally marketed devices, not necessarily a new clinical performance study against specific acceptance criteria for a novel technology.

EasyStim TN28 OTC is intended for the relief of pain associated with sore or aching muscles of the lower back, arms, or legs due to strain from exercise or normal household and work activities.

EasyStim TN28 OTC is a portable, battery powered T.E.N.S. device for pain relief intended for over-the-counter use.
There are totally eight (8) modes that are intended for application to the following areas: Shoulder/ Arm, Lower Back and Leg/Foot.
The accessories include electrode cable and electrodes pads which are placed on the specific body part. Generally, the electrodes are connected to the device through electrode cable. The device produces either a fixed or modulated electrical signal through electrodes normally placed on a patient's skin over the area of pain.
Since the device is battery powered, there is no connection to AC mains supply.

The provided document is a 510(k) Summary for the EasyStim TN28 OTC device, a Transcutaneous Electrical Nerve Stimulator (T.E.N.S.). It focuses on demonstrating substantial equivalence to predicate devices rather than presenting a detailed study proving the device meets specific acceptance criteria in the context of diagnostic or treatment performance.

Here's an analysis based on the information provided, addressing the questions as best as possible within the scope of the document:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state acceptance criteria in terms of clinical performance metrics (e.g., sensitivity, specificity, accuracy) for diagnosis or treatment effectiveness, as would be common for AI/ML-based medical devices or novel therapies. Instead, the substantial equivalence hinges on meeting electrical safety, electromagnetic compatibility, usability, risk management standards, and having similar technical characteristics and indications for use as predicate devices.

The "device performance" reported is primarily a comparison of its technical specifications to those of legally marketed predicate devices.
