Summary
Kinovea® software offers a reliable and user-friendly method for clinical gait analysis. This study confirms its objectivity and low cost, with good to excellent reliability for most parameters, excluding pelvis position.
Area of Science:
- Biomechanics
- Movement Analysis
- Clinical Assessment
Background:
- Need for reliable and accessible clinical gait assessment tools.
- Kinovea® is an open-access software for human movement analysis.
- Limited research on Kinovea®'s repeatability in gait analysis.
Purpose of the Study:
- Evaluate Kinovea® software for objective, quantitative, low-cost, and user-friendly gait evaluation.
- Assess the applicability and reliability of Kinovea® in a clinical setting.
Main Methods:
- Collected gait data from 44 healthy subjects using two smartphones.
- Recorded gait in sagittal and frontal planes.
- Utilized Kinovea® software to compute kinematical and spatio-temporal gait parameters.
Main Results:
- Demonstrated good to excellent intra- and inter-rater reliability for video processing and measurement procedures.
- Identified minimal random measurement errors for most parameters.
- Noted no significant random measurement error, except for pelvis position calculation.
Conclusions:
- Kinovea® software provides an objective, quantitative, reliable, and cost-effective gait evaluation method for clinical use.
- The software is easy to use in clinical settings.
- Accuracy for pelvis position calculation requires further attention.
