The Podoprint® pressure platform system is widely used in routine podiatric clinical practice to measure plantar pressures. It allows non-invasive examination of the patient, and provides fast results with high levels of precision, reliability, and repeatability. Once these conditions have been demonstrated, the clinical and/or research use of baropodometry allows results to be obtained in the field of podology that are far from inconsiderable. The study was designed to evaluate the repeatability and reliability of the platform, and to identify the normal foot pressure parameters.
Records were collected from 52 random healthy individuals, 10 men and 42 women, in two sessions separated by one week. The study variables were: maximum pressure, mean pressure, support surface areas (heel, midfoot, and forefoot), and contact time. Repeatability and reliability were evaluated by calculating the interclass correlation coefficient (ICC) and the coefficient of variation (CV) in the three tests.
The ICCs showed moderate to good repeatability for the variables of interest, and the CVs were all less than 18%. The maximum pressure was under the forefoot (mean 2675.4 ± 513.8 g/cm). The mean contact time of the steps was 0.72 ± 0.07 s.
The Podoprint® system is a reliable tool for evaluating the distribution of plantar pressures in the dynamic study of the barefoot gait of healthy individuals.
Podoprint®压力平台系统广泛应用于常规足病临床实践中，用于测量足底压力。它允许对患者进行非侵入性检查，并提供快速、高精度、高可靠性和可重复性的结果。一旦这些条件得到证明，使用足压计的临床和/或研究就可以在足病学领域获得相当可观的结果。本研究旨在评估平台的可重复性和可靠性，并确定正常足压参数。
从 52 名随机健康个体（10 名男性和 42 名女性）的两次测试中收集记录，两次测试间隔一周。研究变量包括：最大压力、平均压力、支撑表面面积（足跟、中足和前足）和接触时间。通过计算三次测试中的组内相关系数（ICC）和变异系数（CV）来评估可重复性和可靠性。
感兴趣变量的 ICC 显示出中等至良好的可重复性，CV 均小于 18%。最大压力位于前足（平均 2675.4±513.8 g/cm）。步的平均接触时间为 0.72±0.07 s。
Podoprint®系统是一种可靠的工具，可用于评估健康个体裸足步态动态研究中足底压力的分布。
