Abstract

fetched live from OpenAlex

Objectives: The purpose of this study was to develop and establish reliability and validity of a virtual performance measure (VPM) score that encompassed 10 videos in patients with osteoarthritis of the knee joint. Patients' experience and satisfaction were documented. Design: Forty videos were chosen for 10 functional tasks, with four videos showing increasing difficulty for each task. Patients were requested to choose the video that best reflected their own situation. Clinical and radiological findings and self-report and performance measures were completed. Results: Data of 100 patients, 70 (70%) females, mean age: 65 ​± ​9 were examined. The Cronbach's alpha coefficient that examined internal consistency of the VPM score was 0.92. The intraclass correlation value of 0.82 was obtained for test-retest reliability. Factor analysis showed three distinct domains. There was moderate correlations between the VPM score and the self-report and actual performance measures ranging from r ​= ​0.46 to 0.66. The VPM summated score of 10 activities was able to differentiate between candidates and non-candidates for knee arthroplasty, with the area under the curve value of 0.90 indicating excellent predictive validity. The overall patient experience and satisfaction was positive with 67% of participants feeling that virtual care could have an impact on minimizing physical presence in the clinic or hospital. Conclusions: The VPM is a reliable and valid outcome measure in patients with osteoarthritis of the knee joint. This digital tool has the potential to transform osteoarthritis care by providing a valid remote measurement of real-life functional limitations and reduce the burden of time consuming in-person tests.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
