MRI and Biomechanical Data for Reactive and Proactive Stepping in Older Adults

35 participants (26 older adults and 9 young adults) underwent structural MRI scanning and biomechanical testing for reactive and proactive stepping. The dataset likely contains ground reaction force measures, stepping kinematic parameters, and gray matter volume measurements from ten brain regions. The data was uploaded by figshare admin karger and last updated in April 2026.

Use Cases

• Correlating gray matter volume with reactive stepping thresholds based on kinematic data
• Analyzing associations between brainstem volume and balance recovery durations
• Comparing proactive stepping preparation times with pre-central and cerebellar gray matter volume
• Investigating age-related differences in stepping performance linked to prefrontal and amygdala regions

Strengths

• Includes data from 35 participants across two age groups
• Combines structural MRI data with biomechanical ground reaction force and kinematic measurements
• Focuses on ten specific brain regions of interest for gray matter analysis

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is very small (37.2 KB), indicating limited scope
