[Plantar pressure platform as clinical assesment tool in the analysis of foot posture with the foot posture index]. / Die Druckmessplattform als klinisch-diagnostisches Instrument zur Analyse der Fußstatik nach dem Foot Posture Index.

BACKGROUND: The foot posture index is a static measurement that splits up the foot posture into neutral, pronatus and supinatus. However, the relation between the foot posture and the plantar pressure standards is not well known. For this, the objective of this research is to check the relationship between the foot posture and plantar pressure standard. SUBJECTS AND MATERIAL: 144 participants (101 women and 43 men), mean age 25.4 ± 6.3 years, were measured for the FPI. The pedobarometric measurement was made with the plantar pressure platform, we measured total surface (cm2), mean pressure (kPa) and maximum pressure (kPa), these measurements were correlated with the FPI measurements. RESULTS: 288 feet were analysed with regard to the correlation between point 5 of FPI (medial arch height) and the plantar surface total area (p = 0.038): lower arch height and supinated foot are related to the maximum pressure points with p = 0.029. The total contact surface can be determined with the final score of the FPI, the scores of FPI 3, 5 and 6 FPI (r2 = 0.059, p < 0.001) with a 5.9 % prediction. CONCLUSION: The supinatus foot is correlated statistically significantly through the maximum pressure and the plantar surface with the pronatus foot.
