The plantar pressure distribution can be assessed quantitatively by computerized baropodometry such as carpet or insole. An insole-type system with wireless transmission was developed and plantar pressure results were previously validated by force platform. However, the reproducibility of the system had not been determined. Our objective was to evaluate the reliability of the results in different gait cycles, clinical characteristics and in different plantar anatomical sites.
41 healthy adults (age, 34 ± 13 years; body mass index, 25 ± 5 kg/m; 26 [63%], male, 26 [63%] practicing physical activity) were evaluated. Baropodometer evaluations were performed in 3 walking cycles with 100 m each, and the reliability between the cycles was examined. Pressure points on the heel, first metatarsal, fifth metatarsal and total plantar pressure were analyzed and compared.
Moderate agreement was identified between the second and third cycles (ICC, 0.66; 95% CI, 0.14-0.83). Physical activity practitioners showed higher total plantar pressure (70.8 vs 68.2 Kpa; p = 0.04) and higher pressure in the heel (70.7 vs 68.1 Kpa; p = 0.036) in relation to sedentary ones.
The insole was able to assess plant pressure with moderate reliability from the adaptation period.
足底压力分布可通过计算机化足底压力测量法进行定量评估，如使用地毯或鞋垫。我们开发了一种具有无线传输功能的鞋垫式系统，其足底压力测量结果先前已通过测力平台验证。然而，该系统的可重复性尚未确定。我们的目的是评估不同步态周期、临床特征以及不同足底解剖部位结果的可靠性。
对41名健康成年人（年龄34±13岁；体重指数25±5kg/m²；26名[63%]为男性，26名[63%]有体育锻炼习惯）进行评估。使用足底压力测量仪进行3次每次100米的步行周期评估，并检查各周期之间的可靠性。对足跟、第一跖骨、第五跖骨的压力点以及足底总压力进行分析和比较。
第二次和第三次周期之间存在中等程度的一致性（组内相关系数，0.66；95%置信区间，0.14 - 0.83）。与久坐者相比，有体育锻炼习惯者的足底总压力更高（70.8对68.2千帕；p = 0.04），足跟压力也更高（70.7对68.1千帕；p = 0.036）。
从适应期开始，该鞋垫就能以中等可靠性评估足底压力。
