2. to follow an injury through the rehabilitation process and measure progress or lack of progress, in terms of grip or pinch strength, of the therapy regimen or medical treatment.
3. to document baseline grip or pinch strength of the hands and lifting, pulling and pushing strength capabilities of employees and to monitor the strength of employees in the workplace over time.
4. generally, in any situation where the hand grip or pinch strength would be a valuable piece of data in the evaluation of a person who has sustained an injury or suffers a disease to his/her hand(s).
5. to establish an industrial strength testing program in general, and to match the strength of workers to the strength demands of specific job duties in the workplace (lifting, pulling and pushing protocols) in a simulated test.

The provided text is a 510(k) premarket notification letter from the FDA to NK Biotechnical Corporation for their device, the Digit-Grip with LCD, Model DGR 002. It declares substantial equivalence to a predicate device and outlines the indications for use.

Crucially, the document does not contain any information regarding acceptance criteria, device performance studies, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, or training set details.

Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets them based on the provided text. The letter primarily focuses on regulatory approval based on substantial equivalence, not on specific performance data.
