Summary
Camera-based motion capture (CM) shows good reliability for gait speed and stride length but differs from photoelectric walkways (OPT). Use CM consistently as a standalone tool for accurate spatiotemporal gait analysis.
Area of Science:
- Biomechanics
- Motion Analysis
- Gait Science
Background:
- Objective gait assessment is crucial beyond labs.
- 3D markerless motion capture offers a scalable solution.
- Limited data exists on its clinical and field repeatability.
Purpose of the Study:
- Evaluate OpenCap (CM) repeatability and comparability against OptoGait (OPT).
- Assess spatiotemporal gait outcomes in healthy adults.
- Determine practical use in clinical and field settings.
Main Methods:
- Thirty-nine healthy adults performed 10-m overground trials.
- OpenCap (CM) and OptoGait (OPT) systems were used.
- Spatiotemporal gait parameters were analyzed for reliability and correlation.
Main Results:
- Within-device reliability was good-to-excellent for speed, stride length, and cadence.
- CM showed higher mean speed and stride length compared to OPT.
- High correlations were found for speed and cadence, moderate for stride length, and low for double support.
Conclusions:
- OpenCap (CM) offers reliable within-session gait measures.
- Systematic bias exists between CM and OPT.
- CM should be used as a standalone tool, not interchangeably with OPT without calibration.
