Cadence During Usual Pace Gait Speed: Mobility Intervention Response Data

Data from a secondary analysis of the prospective Program to Improve Mobility in Aging (PRIMA) cohort trial, involving 213 older adult participants. It was authored by Daniel S. Rubin and last updated on 2026-05-29. The dataset contains measurements of walking cadence during usual-pace gait speed and 6-minute walk tests, used to evaluate the identification of responders to mobility interventions.

Use Cases

• Predicting improvement in usual-pace gait speed based on changes in walking cadence.
• Identifying responders versus non-responders to mobility interventions using cadence thresholds.
• Validating digitally measurable outcomes for remote and real-world clinical applications.
• Training logistic regression models to predict achievement of minimum clinically important differences (MCIDs).

Strengths

• Dataset is small (5.5 KB), facilitating quick download and initial exploration.
• Analysis is based on a specific cohort of 213 participants from the PRIMA trial.
• Results include specific performance metrics, such as an AUC of 0.90 for predicting gait speed improvement.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The description is detailed but lacks sample data or explicit column definitions.
