The device is designed to be used for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, 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.
The Wireless Pain Relieve Device includes TENS mode. Transcutaneous Electrical Nerve Stimulation (TENS) is a noninvasive, drug free method of controlling pain. TENS uses tiny electrical impulses sent through the skin to nerves to modify your pain perception. TENS does not cure any physiological problem; it only helps control the pain, this activates the underlying sensory nerves. For Transcutaneous Electrical Nerve Stimulation (TENS) Self-adhesive electrodes are placed on the skin close to the area of pain. The user can choose 23 pre-set TENS programs. In each program, the intensity can be adjusted. The Wireless Pain Relieve Device is controlled by means of an APP on a mobile device (phone or table) or remote control. The communication is done via Bluetooth Low Energy. The APP operates on iOS or Android platforms (iOS 8.0 or greater, Android 5.0 or greater).
This document is a 510(k) summary for the Wireless Pain Relieve Device, Model LT5011C, seeking substantial equivalence to a predicate device (Wireless Pain Relieve Device LT5018C). It does not contain information about a clinical study with acceptance criteria and device performance in the manner typically seen for clinical trials. Instead, it focuses on demonstrating substantial equivalence through comparison of technological characteristics and compliance with electrical safety, EMC, and software standards.
Therefore, many of the requested items (acceptance criteria, device performance from a clinical study, sample sizes, data provenance, expert ground truth, adjudication, MRMC study, standalone performance, and ground truth for training) cannot be extracted because this document describes a premarket notification for a Class II medical device based on substantial equivalence, not a detailed clinical study demonstrating new efficacy or performance.
However, I can extract information related to the technical performance and standards compliance tests performed to demonstrate safety and effectiveness for this type of device.
Here's a summary of the available information:
1. Table of acceptance criteria and the reported device performance (based on technical specifications and safety/EMC standards):

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
Not applicable. This is not an AI/algorithm-only device. Its performance is assessed through its electrical output characteristics and safety features.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
Not applicable. The "ground truth" here is adherence to engineering specifications and international safety standards (IEC 60601 series, ISO 10993).
8. The sample size for the training set:
Not applicable. There is no training set in the context of an AI/ML device.
9. How the ground truth for the training set was established:
Not applicable.
