Summary
The GaitMat II (GM) is a reliable and valid clinical gait analysis tool, showing excellent agreement for timing variables and clinically insignificant differences for distance variables compared to a gold standard system.
Area of Science:
- Biomechanics
- Clinical Gait Analysis
- Rehabilitation Technology
Background:
- Accurate measurement of spatiotemporal gait variables is crucial for evidence-based clinical decisions in gait dysfunction.
- The GaitMat II (GM) is a portable and affordable clinical gait analysis system.
Purpose of the Study:
- To assess the accuracy, reliability, and validity of the GaitMat II (GM) for clinical gait analysis.
Main Methods:
- Investigated switch placement variability across three GM systems.
- Compared GM measures with simultaneous Vicon motion analysis system data.
- Utilized a repetitive dynamic signal for system comparison.
Main Results:
- Switch placement variability on GM systems was less than typical gait variable variability.
- Excellent agreement between GM and Vicon for timing variables.
- Poor agreement for distance variables, but differences were clinically insignificant for adult step/stride length.
Conclusions:
- The GaitMat II (GM) demonstrates reliability and validity as a clinical gait analysis tool.
- The system is suitable for clinical use despite minor distance measurement discrepancies.
