Accuracy of Video-Based Gait Analysis Using Pose Estimation during Treadmill Walking Versus Overground Walking in Persons after Stroke

CONCLUSIONS: Video-based gait analysis using pose estimation provides accurate measurements of step length, step time, and hip and knee kinematics during overground and treadmill walking in persons after stroke. Generally, sagittal videos of overground gait provide the most accurate results.IMPACT: Many clinicians lack access to expensive gait analysis tools that can help identify patient-specific gait deviations and guide therapy decisions. These findings show that video-based methods that require only common household devices provide accurate measurements of a variety of gait parameters in persons after stroke and could make quantitative gait analysis significantly more accessible.PMID:37682075 | DOI:10.1093/ptj/pzad121
