Ground reaction force (GRF) trajectories capture kinetic alterations in stance-phase loading, propulsion, and mediolateral control. This study presents GaitScreen, a GRF-based framework for post-acquisition prioritisation of already recorded healthy-control and pathological-gait trials. GaitScreen converts vertical,...

Human gait is a widely studied motor behavior, yet direct observation of skeletal muscle dynamics during walking remains limited. We present a novel multimodal gait dataset that integrates real-time B-mode ultrasound imaging with synchronized motion and surface electromyography (EMG) data. Twenty-six healthy adults (...

Accurate estimation of ground reaction forces (GRFs) is fundamental to gait analysis and supports functional gait assessment, surgical planning, and rehabilitation. We propose a physics-learning hybrid framework that combines linked-segment dynamics with a bidirectional long short-term memory network to estimate vertic...
