 This study demonstrated that ultra-wideband UWB sensors can accurately estimate the three key parameters for diagnosing gate disorders, stride length, SL, foot clearance, FC, and foot progression angle, FPA, when compared to motion capture systems, MCS. The UWB sensors displayed average errors of 45.84 mm, 7.60 mm, and 2.82 degrees for SL, FC, and FPA, respectively, which is comparable to the error levels observed in a previous study that used inertial measurement units, IMUs. These findings suggest that UWB sensors can be effectively utilized as part of a sensor system for analyzing mobile gate systems. This article was authored by G.
