• Rearfoot motion during gait may influence athletic footwear choices and injury prevention, yet rearfoot motion during stance has not been fully characterized. Rearfoot pronation is typically used to categorize arch types into structural and functional groups, yet the amount of rearfoot plantar flexion during stance has not been determined. The objective of this study is to characterize this motion of the calcaneus during the stance phase of gait and its relationship to arch type. The functional and structural foot arch types of thirty participants were characterized using a modified longitudinal arch angle (LAA) test. Segmental rotation was used to determine independent rotations of the calcaneus. Calcaneal plantar flexion was found during the midstance phase. Possible relationships to functional or structural arch types were identified. This signifies the importance of calcaneal plantar flexion in characterizing foot arch type and of using segmental analysis in identifying key bone rotations.
