Table 1_Measurement properties of the SARC-T: test-retest reliability, agreement and minim

55 institutionalized older adults with sarcopenia participated in a test-retest study of the SARC-T chair-rise velocity measure. The dataset includes reliability metrics such as an ICC of 0.93, a standard error of measurement of 0.017 m/s, and a minimal detectable change of 0.05 m/s. It was authored by Blanca Pedauyé-Rueda and last updated on 2026-05-29.

Use Cases

• Validate the reliability of a chair-rise velocity test based on reported ICC and concordance correlation coefficients.
• Assess measurement error and minimal detectable change for longitudinal studies of physical function in sarcopenia.
• Analyze potential systematic bias in repeated clinical measurements using the provided Bland–Altman analysis results.
• Model session effects on biomechanical measurements in older adults using the linear mixed-effects model parameters.

Strengths

• Includes specific reliability statistics: ICC of 0.93 (95% CI 0.88–0.96) and CCC of 0.93.
• Quantifies measurement error with a standard error of measurement of 0.017 m/s and a minimal detectable change of 0.05 m/s.
• Study protocol is described in detail, including a 5-day interval between test sessions and standardized conditions.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Data is specific to a population of 55 institutionalized older adults with sarcopenia, limiting generalizability.
• The dataset is very small at 14.7 KB, indicating limited scope.
