This device is intended for medical purposes to provide mobility to persons restricted to a seated position.
The HEARTWAY Power Wheelchair, P25 is an indoor / outdoor power chair that is battery operated. It has a base with four-wheeled with a seat, and armrests. The movement of the power chair is controlled by the rider who uses hand controls located at the top of the steering column. The device can be disassembled for transport and is provided with an external battery charger.
The HEARTWAY Power Wheelchair, P25 (K132856) is a powered wheelchair intended to provide mobility to persons restricted to a seated position. The device's performance was evaluated against a series of ISO 7176 standards related to wheelchairs and other relevant standards.

2. Sample Size Used for the Test Set and Data Provenance:
The document does not explicitly state the sample size used for performance testing of the device itself (P25). It does mention various ISO and other standards that the device complies with, implying that testing was conducted according to the methodologies defined by these standards. The data provenance is Taiwan, R.O.C., where the manufacturer is located. The nature of these tests (e.g., laboratory simulations, physical trials) is characteristic of prospective performance evaluations during product development and regulatory submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
This type of information (number and qualifications of experts) is not typically detailed for performance testing of a medical device like a powered wheelchair, as the ground truth is established by objective measurements and adherence to engineering standards. The compliance with ISO and other recognized standards serves as the basis for "ground truth" concerning the device's physical and electrical performance.
4. Adjudication Method for the Test Set:
Not applicable for this type of performance testing. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies or image review where subjective interpretation is involved. For this device, compliance is determined by objective measurements against established standard criteria.
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 diagnostic or interpretive device, but rather a mobility device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This is a physical device, and its performance is evaluated through standardized physical and electrical tests.
7. The Type of Ground Truth Used:
The ground truth is established by adherence to internationally recognized engineering and safety standards (e.g., ISO 7176 series, CISPR, EN, IEC, ANSI/RESNA WC/Vol.2) and UL certifications. These standards define objective performance criteria and test methods for powered wheelchairs.
8. The Sample Size for the Training Set:
Not applicable. This is not a machine learning or AI-driven device that requires a training set.
9. How the Ground Truth for the Training Set was Established:
Not applicable for the same reason as above.
