Consistency of the disability degree evaluated using the remote assessment and the bedside assessment of Longshi Scale.
Weighted kappa(wK) and Bland-Altman were used to determined the consistency between the results of remote assessment method and bedside assessment method. The interpretation of wK scores was in accordance with published standards (values\>0.75 indicating excellent agreement beyond chance; 0.4\~0.75, moderate agreement beyond chance; \<0.4, poor agreement beyond chance).
Time frame: Within 24 hours
The test-retest reliability of the remote video assessment
the result of remote assessment test-retest was analyzed by Weighted kappa(wK) scores.The interpretation of wK scores was in accordance with published standards (values\>0.75 indicating excellent agreement beyond chance; 0.4\~0.75, moderate agreement beyond chance; \<0.4, poor agreement beyond chance).
Time frame: Within 24 hours after first evaluation
Satisfaction survey of remote assessment
The satisfaction survey data were summarized as mean±standard deviation, and also summarized as the percentage of satisfaction categories.
Time frame: Within 24 hours after the remote assessment
Assessment duration
The assessment duration was analyzed by independent t-test.
Time frame: Within 24 hours
