    Intended Use

    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) and lower extremities (leg) due to strain from exercise or normal household work activities. And to be used for the symptomatic relief and management of chronic, intractable pain and relief of pain associated with arthritis.

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

    Device Description

    LT5019 is designed to be used at home, by adults of all genders. The Smart Pain Reliever includes TENS, EMS (including MASSAGE Program). Transcutaneous Electrical Nerve Stimulation (TENS) is a noninvasive, drug free method of controlling pain. EMS works by sending electronic pulses to the muscle needing treatment; this causes the muscle to exercise passively. The Smart Pain Reliever device is controlled by means of an APP on a mobile device (phone or table). The communication is done via Bluetooth Low Energy. The APP operates on IOS and Android platforms (IOS 8.0 or greater, Android 5.0 or greater).

    AI/ML Overview

    The provided text describes the 510(k) summary for the "Smart Pain Reliever, Model LT5019," a Transcutaneous Electrical Nerve Stimulator (TENS) and Electrical Muscle Stimulator (EMS). This document aims to demonstrate substantial equivalence to legally marketed predicate devices, not to prove the device meets specific acceptance criteria related to its clinical effectiveness with an AI component or analysis of diagnostic performance.

    Therefore, many of the requested details about acceptance criteria for AI/diagnostic performance, sample sizes for test/training sets, expert consensus, adjudication methods, MRMC studies, standalone performance, and ground truth establishment (which are typical for AI/diagnostic device studies proving clinical utility) are not present in this regulatory submission document.

    This document focuses on:

    • Technological equivalence: Comparing the technical specifications (e.g., waveform, pulse duration, frequency, power source) of the new device to predicate devices.
    • Compliance with safety standards: Demonstrating that the device meets relevant electrical safety, electromagnetic compatibility (EMC), biocompatibility, software verification/validation, and usability standards.

    Here's what can be extracted from the provided text regarding device performance and criteria based on the regulatory context:

    Acceptance Criteria and Reported Device Performance (as inferred from a 510(k) for a TENS/EMS device)

    For this type of device, "acceptance criteria" are primarily related to meeting established electrical and safety performance specifications and demonstrating that these specifications are either equivalent to predicate devices or fall within accepted physiological/safety limits. The performance "reported" is primarily in the form of meeting these technical specifications rather than clinical diagnostic metrics.
