Key Findings
- 01Statistically significant correlations (r=0.66-0.95) were found between kinematic parameters and CoP data, indicating validity.
- 02Good to excellent test-retest reliability (ICCs 0.66-0.95) was observed for kinematic parameters.
- 03Bland-Altman plots showed no significant systematic bias.
Application
Design takeaway
Incorporate instrumented feedback and objective data collection into the design of assessment tools for human performance to enhance accuracy and reliability.
How to apply
When designing products or systems that require users to maintain balance or stability, consider integrating sensors to capture objective performance data rather than relying solely on subjective observation.
Project actions
- 01Consider how to measure user performance objectively in your design project.
- 02Think about using sensors or data logging to gather quantitative feedback.

Strengths & Limitations
Strengths
- +Utilized a test-retest design to establish reliability.
- +Correlated kinematic data with established CoP measures for validity.
Limitations
The cost and complexity of instrumented equipment can be a barrier for some design projects.
Reliability & validity
The study established both validity (correlation with CoP) and reliability (test-retest ICCs, SEM, MDC) of the kinematic parameters derived from the unstable board.
Think critically
How might the principles of objective measurement used in this study be applied to assess other aspects of user interaction, such as cognitive load or reaction time?
Design Principles
"Objective measurement enhances the validity and reliability of human performance assessment."
Traditional dynamic balance assessments often rely on subjective scoring. This research demonstrates a method for incorporating objective, instrumented data, which can lead to more precise and repeatable evaluations of user performance and stability.
What This Means for Your Design
Using a special board with sensors can accurately measure how well someone balances, and the results are consistent when tested again later.
How to use in your project
- 1.This study provides a methodology for validating objective measurement tools for user performance.
