Postural Sway and Breathing Movement Data During Cognitive Tasks

Encompassing biomechanical measurements from a study investigating the relationship between breathing movement and postural sway during cognitive tasks. It includes center of pressure (COP) data from a force plate, 3D motion capture of leg joints (ankle, knee, hip), and breathing movement measurements under quiet standing and mental arithmetic conditions. The analysis found a significant positive correlation (r = 0.75) between the change ratio of breathing amplitude and COP amplitude.

Use Cases

• Analyze the correlation between the change ratio of breathing amplitude and the change ratio of center of pressure (COP) amplitude to model postural control mechanisms.
• Compare breathing rate and breathing movement amplitude between quiet standing and cognitive task conditions to quantify task-induced physiological changes.
• Investigate the relationship between motion capture data from ankle, knee, and hip joints and COP variability during dual-task postural control.
• Use the calculated change ratios for each variable from quiet standing to cognitive task to identify key predictors of reduced postural sway.

Strengths

• Data includes synchronized multi-modal measurements: center of pressure, 3D joint motion, and breathing movement.
• Analysis identified a specific, statistically significant correlation (r = 0.75, p < 0.01) between key variables.
• Measurements were taken under controlled experimental conditions (quiet standing vs. mental arithmetic task).

Limitations

• Sample size and number of rows are unknown, limiting assessment of statistical power and generalizability.
• The subject demographic (young adults) is specified in the description but not the sample data, indicating a potential age bias.
• Data granularity and specific column definitions are unavailable, complicating direct reuse.
