    Abstract:

    Objective To explore the correlation between plantar pressure distributions and arch structural features in different standing positions. Methods Plantar pressures of 13 healthy adult males were tested, and foot CT scan and foot bone model reconstruction were then performed to establish arch digital characterization. On this basis, the correlation between plantar pressure measurement indexes and arch characteristics measurement parameters was analyzed. Results Forefoot peak pressure ( FPP) was positively correlated with the medial lateral longitudinal arch height, the medial / lateral longitudinal arch index and body weight, and negatively correlated with the medial / lateral longitudinal arch angle during standing with foot at 0°; it was positively correlated with the medial / lateral longitudinal arch length, the medial longitudinal arch height, the plantar triangle area and body weight during standing with foot at 30°; it was positively correlated with the medial / lateral longitudinal arch height and the medial longitudinal arch index, and negatively correlated with the medial longitudinal arch angle during standing with foot at 60°. Midfoot peak pressure (MPP) was positively correlated with the medial / lateral longitudinal arch length and the plantar triangle area during standing with foot at 0°; it was positively correlated with the medial / lateral longitudinal arch length, the medial / lateral longitudinal arch angle and the plantar triangle area, and negatively correlated with the medial / lateral longitudinal arch index during standing with foot at 30°; it was positively correlated with the medial / lateral longitudinal arch length, the plantar triangle area and body weight during standing with foot at 60°. Rearfoot peak pressure ( RPP) was positively correlated with the medial / lateral longitudinal arch height, the medial / lateral longitudinal arch index and body weight, and negatively correlated with the medial / lateral longitudinal arch angle during standing with foot at 0°; it was only positively correlated with body weight, but not with characteristic parameters of foot arch during standing with foot at 30° and 60°. Conclusions There is a different correlation between plantar pressure distributions 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 positions.
