Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Agreement between the SPPB total score and gait speed measured by the MEDISTEP M Pro and those measured manually by an examiner, assessed using the intraclass correlation coefficient | — |
Secondary
| Measure | Time frame |
|---|---|
| Measurement bias and 95% limits of agreement between the two methods using Bland–Altman analysis;ICC for each SPPB subcomponent (gait speed, chair stand, balance);Concordance in classifying low physical function (SPPB total =9) between the two methods (Cohen's kappa and percent agreement) | — |
