摘要: Evaluating the effects of load carriage on gait balance stability is important in various applications. However, their quantification has not been rigorously addressed current literature, partially due to lack relevant computational indices. The novel Dynamic Gait Measure (DGM) characterizes by quantifying relative inertia terms zero-moment point, ground projection center mass, and time-varying foot support region. In this study, DGM formulated parameters that explicitly reflect strategy a given walking pattern used for evaluation distinct loaded walking. observed adaptations caused (decreased single duration, effects, step length) result decreased values (p < 0.0001), which indicate motions are more statically stable compared with unloaded normal Comparison other common indices (the maximum Floquet multiplier margin stability) validates unique characterization capability DGM, consistently informative presence added load.
