What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Consistency of the disability degree evaluated using the electronic version and the paper version of Longshi Scale | Weighted kappa was used to determine the consistency of the disability degree evaluated using the electronic version and the paper version of Longshi Scale. Kappa value ranges from 0 to 1 and the thresholds for kappa reliability are as follows: poor (κ = 0.00-0.20), fair (κ= 0.21-0.40), moderate (κ = 0.41-0.60), good (κ = 0.61-0.80),and very good (κ = 0.81-1.00). | Within 48 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of evaluators' preference | After completing all the evaluations, each evaluator was asked to reveal their preferred version (paper version, electronic version or no preference). Chi-square test was used to compare the proportion of evaluators' preference. | Within 48 hours | 
| Time required | Time required in each section of electronic version and paper version of Longshi Scale. | Within 48 hours | 
| Test-retest reliability of electronic version Longshi Scale | Weighted kappa was used to determine test-retest reliability of electronic version Longshi Scale. Kappa value ranges from 0 to 1 and the thresholds for kappa reliability are as follows: poor (κ = 0.00-0.20), fair (κ= 0.21-0.40), moderate (κ = 0.41-0.60), good (κ = 0.61-0.80),and very good (κ = 0.81-1.00). | Within 48 hours after first evaluation |
