Determining the Differences in Gait in Various Walking Speeds Between People With Pes Planus and Normal Medial Longitudinal Arches

Dr. Michael Bird, Faculty Mentor
The purpose of this study was to determine differences in gait between subjects with Pes Planus and normal medial longitudinal arches (NMLA). Each subject had an ink footprint taken of their right foot using a Harris Inkmat. The resting calcaneal position was measured by a goniometer. Subjects walked across a force plate while being videotaped. A one way ANOVA test showed significant differences in resting calcaneal position (p<0.001; effect size: 0.951), anterior posterior relative braking peak force (slow p<0.054; effect size: 0.388 and fast p<0.083; effect size: 0.369), anterior posterior braking impulse force (slow p<0.019; effect size: 0.516 and fast p<0.021; effect size: 0.558), pronation at toe-off (slow p<0.063; effect size: 0.368), and vertical relative braking peak (fast p<0.094; effect size: 0.348). Valgus index showed no significant differences. Pronation values were significant during toe-off during the slow trial. Pes Planus subjects spent more energy than NMLA subjects while braking.
