Table 1.
Mean and SD (or median and interquartile range) for all physical function assessments performed for each of the three trials by the 19 participants. P-values reflect results from one-way repeated measures ANOVA assessing differences across trials.
Table 2.
Test-retest reliability and interpretation for all physical function assessments between trial 1 and trial 2, and between trial 2 and trial 3. Interpretation of intraclass correlation coefficient (ICC) values were based on classifications of poor (ICC < 0.5), moderate (0.5–0.75), good (0.75–0.9), or excellent (>0.9) [23].
Fig 1.
Bland-Altman plots of differences in test scores between repeated testing occasions (session 1 minus session 2, and session 3 minus session 2) vs. averages of paired measurements for the five-times STS (5-STS) test (panels A and B), 30-second STS (30-STS) test (panels C and D), single-leg balance (panels E and F), four-square step test (FSST; panels G and H), and total score for the Short Physical Performance Battery (SPPB; panels I and J).
The dashed lines indicate the 95% confidence interval of the mean difference between trials. Shaded areas indicate 95% limits of agreement.

Bland-Altman plots of differences in test scores between repeated testing occasions (session 1 minus session 2, and session 3 minus session 2) vs. averages of paired measurements for gait speed over 2.4 m at both usual (panels A and B) and fast speed (panels C and D), and gait speed over 4 m at both usual (panels E and F) and fast speed (panels G and H).
The dashed lines indicate the 95% confidence interval of the mean difference between trials. Shaded areas indicate 95% limits of agreement.
