Objective To explore the correlation between plantar pressure distribution and arch structural features in different standing positions. Methods First, Thirteen healthy adult men were tested for plantar pressure, and then foot CT scan and foot bone model reconstruction were performed to establish arch digital characterization. On this basis, the correlation between plantar pressure measurement indexes and arch characteristics measurement parameters was analyzed. Of these, the feet were standing at 0°, 30° and 60° respectively during the plantar pressure test; The plantar pressure measurement indexes included forefoot peak pressure (FPP), midfoot peak pressure (MPP) and rearfoot peak pressure (RPP); The arch characteristics measurement parameters included medial longitudinal arch length, medial longitudinal arch height, lateral longitudinal arch length, lateral longitudinal arch height, medial longitudinal arch angle, lateral longitudinal arch angle, medial longitudinal arch index, lateral longitudinal arch index, and plantar triangle area. Results FPP was positively correlated with the medial and lateral longitudinal arch height, the medial and lateral longitudinal arch index and body weight, and negatively correlated with the medial and lateral longitudinal arch angle when standing at 0°; it is positively correlated with the medial and lateral longitudinal arch length, the medial longitudinal arch height, the plantar triangle area and body weight when standing at 30°; it is positively correlated with the medial and lateral longitudinal arch height and the medial longitudinal arch index, and negatively correlated with the medial longitudinal arch angle when standing at 60°. MPP was positively correlated with the medial and lateral longitudinal arch length and the plantar triangle area when standing at 0°; it is positively correlated with the medial and lateral longitudinal arch length, the medial and lateral longitudinal arch angle and the plantar triangle area, and negatively correlated with the medial and lateral longitudinal arch index when standing at 30°; it is positively correlated with the medial and lateral longitudinal arch length, the plantar triangle area and body weight when standing at 60°. RPP was positively correlated with the medial and lateral longitudinal arch height, the medial and lateral longitudinal arch index and body weight, and negatively correlated with the medial and lateral longitudinal arch angle when standing at 0°; it is only positively correlated with body weight, but not with characteristic parameters of foot arch when standing at 30° and 60°. Conclusions There is different correlation between plantar pressure distribution and arch characteristics in different standing positions. The results can provide theoretical basis for clinical diagnosis, treatment and prevention of foot pathology caused by different standing posture.
