Measuring Foot Progression Angle during Walking Using Force-Plate Data

Foot progression angle (FPA) is a gait-related clinical measurement commonly used for assessing the rotational profile of lower extremity. This study examined accuracy two methods based on force-plate data estimating FPA during walking by comparing them with reference method using motion capture system. Ten healthy adults performed series overground trials at three different speeds: slow, preferred and fast. was estimated from center pressure—one previously reported in literature, novel proposed here. The each these were compared determined kinematic data. Results showed that more accurate precise when measuring speed conditions than literature. mean absolute error obtained this 3.3° ± 2.1° slow speed, 2.0° 1.2° fast no significant effect gait (p > 0.05). These findings suggest here valid determining various speeds. In absence data, constitutes an attractive alternative FPA.
