Abstract

Abstract Introduction: Abnormal plantar pressures are the distinguishing feature of various pathological conditions and abnormalities. For accurate and rapid detection of patients and as an aid to correct treatment we use pressure platforms. Therefore, it is essential to evaluate the reliability and repeatability of these devices before making clinical decisions to be sure of our results. The purpose of this study was to determine the reliability of the Kinefis Podia platform in static and dynamics. Material and methods: To determine the reliability and repeatability of the Kinefis Podia platform for the study of plantar pressures in statics and dynamics parameters forty-seven healthy individuals stood and walked on the pressure platform. Three measurements were recorded with each foot in statics and dynamics position and two sessions were performed. The data obtained were several variables of interest for inter-session reliability were calculated using intraclass correlation coefficients (ICC), standard error of measurement (SEM), percentage error and coefficient of variation (CV). Results: Reliability and intersession between static and dynamic sessions produced moderate to excellent CHF, low SEM, low percentage errors, and low CV. Static trials had higher ICCs, lower error rates, and lower CVs compared to dynamic trials. Inter-session reliability also had higher ICCs, lower percentage errors, and lower CVs compared to inter-session reliability. Conclusion: This study demonstrates that the Kinefis Podia platform is a reliable and reproducible device to collect footprint pressures. Static tests produce better reliability, probably due to the inherent great variability during dynamic running. These results can be used as a basis for future studies and to determine a priori sample sizes for research using the Kinefis Podia Platform.
