A software system used with the Microsoft Kinect v2 intended to support the physical rehabilitation of adults in the clinic and at home. The system includes rehabilitation exercises for the upper extremity, trunk, and lower extremity with audiovisual feedback & graphic movement representations for patients as well as videos of the patients performing the exercises which can be remotely accessed by the clinician. Patient assessment, exercise guidance and approval by a medical professional is required prior to use.
Not Found
This FDA 510(k) clearance letter for the Vera device does not contain the detailed information necessary to fully answer your request regarding acceptance criteria and the specifics of the study that proves the device meets those criteria. The letter primarily confirms the device's substantial equivalence to predicate devices and outlines regulatory obligations.
However, based on the provided text, I can infer some information and highlight what is explicitly missing.
Information that CAN be extracted or inferred:
- Device Name: Vera
- Intended Use: A software system used with the Microsoft Kinect v2 intended to support the physical rehabilitation of adults (upper extremity, trunk, and lower extremity) in the clinic and at home, with audiovisual feedback, graphic movement representations for patients, and remote access to patient exercise videos for clinicians. Patient assessment, exercise guidance, and approval by a medical professional are required prior to use.
- Regulatory Status: Cleared as a Class II medical device (Product Code LXJ), Regulation Number 21 CFR 890.5360 (Measuring Exercise Equipment).
- Use Type: Prescription Use.
Information that is NOT present in the provided text and is crucial for your request:
- A table of acceptance criteria and the reported device performance: This detailed information is typically found in the 510(k) summary or the full submission, not in this clearance letter.
- Sample sizes used for the test set and data provenance: Not mentioned.
- Number of experts used to establish the ground truth for the test set and their qualifications: Not mentioned.
- Adjudication method for the test set: Not mentioned.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done, or its effect size: Not mentioned, and generally less common for this type of device (measuring exercise equipment).
- If a standalone performance (algorithm only without human-in-the-loop performance) was done: Not explicitly mentioned, though the device has a standalone component (the software system itself). The performance metrics for this standalone component are what's missing.
- The type of ground truth used: Not mentioned. For a rehabilitation device, this could involve motion capture systems, clinical assessments, or expert observation.
- The sample size for the training set: Not mentioned.
- How the ground truth for the training set was established: Not mentioned.
To obtain the specific information you are looking for (acceptance criteria, study details, performance metrics, ground truth methods, sample sizes), you would need to access the full 510(k) submission for K192474, which may be available through the FDA's website or by filing a Freedom of Information Act (FOIA) request. The public 510(k) summary, if available, would be the most likely place to find a high-level overview of the performance data.
§ 890.5360 Measuring exercise equipment.
(a)
Identification. Measuring exercise equipment consist of manual devices intended for medical purposes, such as to redevelop muscles or restore motion to joints or for use as an adjunct treatment for obesity. These devices also include instrumentation, such as the pulse rate monitor, that provide information used for physical evaluation and physical planning purposes., Examples include a therapeutic exercise bicycle with measuring instrumentation, a manually propelled treadmill with measuring instrumentation, and a rowing machine with measuring instrumentation.(b)
Classification. Class II (special controls). The device, when it is a measuring exerciser or an interactive rehabilitation exercise device for prescription use only, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 890.9.
