Cadence During 6-Minute Walk Test for 213 Older Adults

213 participants from the prospective Program to Improve Mobility in Aging (PRIMA) cohort trial had their walking cadence measured during usual-pace gait speed testing and the 6-minute walk test (6MWT). The dataset, authored by Daniel S. Rubin and shared under a CC-BY-4.0 license, was used to evaluate whether changes in cadence could identify responders to a walking intervention. The data was last updated on 2026-05-29.

Use Cases

• Developing predictive models for mobility intervention response based on cadence change thresholds.
• Validating walking cadence as a digital biomarker for gait speed improvement.
• Comparing the sensitivity of cadence versus traditional in-person mobility assessments like the 6MWT.

Strengths

• Data from 213 participants in a defined clinical cohort (PRIMA trial).
• Analysis includes specific performance metrics (AUC of 0.90 for gait speed, 0.80 for 6MWT distance).
• Provides a concrete, digitally measurable threshold (increase of ≥3 steps/min) for identifying responders.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Data scale is very small at 5.5 KB, indicating limited scope.
• Data may reflect the specific population bias inherent to the PRIMA cohort study.
