This FDA 510(k) summary (K190737) describes the substantial equivalence of the Solax Electric Scooter to a previously cleared predicate device, rather than providing details of a study akin to those conducted for AI/ML-based medical devices. Therefore, much of the requested information regarding acceptance criteria, human reader studies, and ground truth establishment for AI systems is not applicable or present in this document.

However, I can extract information related to the performance testing and comparison to the predicate device, framing it as acceptance criteria and proof of meeting them within the context of a non-AI medical device.

Device Name: Solax Electric Scooter (Models: S204311M, S204161, S204143)
Intended Use: A motor driven, indoor and outdoor transportation vehicle with the intended use to provide mobility to a disabled or elderly person limited to a seated position.

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

For a traditional medical device like this electric scooter, "acceptance criteria" are typically defined by performance standards (e.g., ISO standards) and by demonstrating equivalence to a predicate device. The "reported device performance" is the successful compliance with these standards and the demonstration that any differences from the predicate do not raise new safety or effectiveness concerns.

The remaining numbered points are primarily for AI/ML device studies and are not directly applicable to a traditional device 510(k) submission like this one, which relies on performance testing and substantial equivalence to a predicate.

2. Sample sized used for the test set and the data provenance:

• Sample Size: Not applicable in the context of an AI/ML test set. The study involves testing physical units of the scooter according to various ISO standards. The specific number of units tested is not detailed in this summary but would be determined by the requirements of each standard.
• Data Provenance: Not applicable. The "data" are results from physical performance and biocompatibility testing of the device itself, rather than a dataset of patient information. The testing would have been conducted by the manufacturer or a certified testing lab, likely in China, given the manufacturer's location. The testing is prospective in the sense that it's performed on the manufactured product to demonstrate compliance.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Not applicable. "Ground truth" in the AI/ML sense (e.g., expert annotation of medical images) is not relevant here. Compliance with ISO standards is determined by prescribed test methods and objective measurements.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

• Not applicable. This is not a human reader study requiring adjudication. Test results are objectively measured against standard specifications.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

• Not applicable. This is not an AI-assisted device or an imaging device requiring human reader studies.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

• Not applicable. This device does not use an algorithm in that capacity.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc):

• Not applicable in the AI/ML sense. The "ground truth" for this device's performance is defined by the objective pass/fail criteria of the various ISO performance and safety standards, and the direct comparison of its physical and functional characteristics to the predicate device.

8. The sample size for the training set:

• Not applicable. This is not an AI/ML device that requires a training set.

9. How the ground truth for the training set was established:

• Not applicable.
