The longitudinal plantar arch (LPA) perform biomechanics functions in the foot. The aim of this study was to compare the relationship between different index to measure the LPA of the foot. The arc index, Staheli index, Viladot classification and Feiss line were compared. In the transversal study, the experimental samples were soccer players females with age between 13 to 19 years. The measure were performed by plantigraphy, with out Feiss line. Although non significant the higher agreement was reached between the arch index and Staheli index. This comparison presented a Cohen's Kappa coefficient of 0,32 and 0,30 for right and left foot respectively. The comparison between arch index either with Feiss line or Staheli index presented low agreement. In conclusion this study showed low agreement between methods to measure the LPA.154850860
