How many strides are needed for reliable markerless gait analysis?
Carvalho, Andreia; Vanrenterghem, Jos; Pataky, Todd C.; Robinson, Mark A.; Veloso, António P.; Moniz-Pereira, VeraBackground/aim: Markerless motion capture is an emerging tool for gait analysis. In some populations, e.g., older adults, traditional gait analysis poses practical challenges, such as reduced assessment tolerance, and the number of strides collected can be limited. This study aimed to investigate the influence of the number of strides on test-retest reliability and measurement error of markerless gait biomechan...
Construct validity of markerless three-dimensional gait biomechanics in healthy...
Carvalho, Andreia; Vanrenterghem, Jos; Cabral, Sílvia; d'Assunção, Ana M.; Carnide, Filomena; Veloso, António P.; Moniz-Pereira, VeraBackground and aim: Gait changes due to aging can result in functional limitations and a higher risk of falls, with older adults showing alterations in joint angles and moments. Marker-based gait analysis is not widely used in clinical settings due to its complexity and discomfort, especially in older adults. Recent advances in markerless motion capture, such as Theia3D, offer a promising alternative. This stud...

Markerless three-dimensional gait analysis in healthy older adults: test–retest...
Carvalho, Andreia; Vanrenterghem, Jos; Cabral, Sílvia; Assunção, Ana; Fernandes, Rita; Veloso, António P.; Moniz-Pereira, VeraIn older adults, gait analysis may detect changes that signal early disease states, yet challenges in biomechanical screening limit widespread use in clinical or community settings. Recently, a markerless method from multi-camera video data has become accessible, making screenings less challenging. This study evaluated the test-retest reliability and measurement error of markerless gait kinematics and kinetics ...
