Comparison of Plantar Loading Characteristics During Two Fundamental Badminton Movements Between the Individuals With Cavovarus Foot Deformity and the Ones With Normal Foot

Purpose: Some deformities that increase the risk of injury including cavus foot are not correctable yet and can only be limited by prevention and taking care of external causes. The current study aimed at determining if foot type (cavus or normal) resulted in loading differences during badminton fundamental movements, considering the prevalence of cavovarus foot deformity and the important role of the foot in sports - especially the sports that suddenly impose forces with different speeds on foot. Methods: Twenty healthy subjects (10 cases with normal feet and 10 with high arch feet) completed 5 trials in each condition, while in-shoe pressure data were collected at 100 Hz. Peak pressure and mean pressure were analyzed among the subjects in 5 major anatomical regions of the foot using the independent t test in SPSS version 20. Foot type was determined by foot posture index (FPI) (α
