Footwork Pro System Reproducibility of Static and Dynamic Plantar Pressure Indicators

Abstract

Objective

The purpose of this study was to identify the reproducibility of the Footwork Pro plate in the measurement of static and dynamic plantar pressure in healthy adults.

Methods

We performed a reliability study using a test-retest design. The sample consisted of 49 healthy adults of both sexes, aged 18 to 64. Participants were assessed on the following 2 different occasions: the initial moment and 7 days later. Measurements for the static and dynamic plantar pressure were performed. We used the Student t test for paired data, the concordance correlation coefficient, and bias to estimate reliability.

Results

Plantar pressure values for the static condition (peak plantar pressure, plantar surface contact area, and body mass distribution) and dynamic condition (peak plantar pressure, plantar surface contact area, and contact time) between the first and second measurements did not present statistically significant differences. The concordance correlation coefficients were ≤0.90, and the biases were of low magnitude.

Conclusion

The findings showed that the Footwork Pro system offered clinically acceptable reproducibility to identify static and dynamic plantar pressure and thus may be a reliable tool for this purpose.
