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

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.
