Pedobarography is frequently employed for the identification and characterisation of foot pathologies in paediatrics. However, the lack of standardised normalisation methods presents a challenge for cross-age comparisons. This cross-sectional study provides normative plantar pressure data for typically developing children aged 4-17 years and compares normalisations and explanatory powers of parameters measuring peak and total load.
Dynamic foot pressure of 101 typically developing children aged 4-17 years was measured at self-selected speed using the mid-gait protocol. They were divided into five age groups: 4-6, 7-8, 9-11, 12-14 and 15-17 years old. Force and pressure variables measuring peak and total load were normalised by body weight or scaled by maximum value and the foot region where the peak pressure occurred was identified.
The absolute values demonstrated an increase in load with advancing age. In contrast, when normalised to body weight, peak pressure and pressure time integrals decreased. The scaled peak pressure showed a load shift to the forefoot. The results indicate that the normalised parameters exhibit superior qualitative significance, suggesting a more dynamic gait pattern and improved morphology of the foot in relation to body weight with increasing age.
This study shows that standardisation of the measurement protocol is imperative because results in typically developing children can vary depending up parameter selection and normalisation technique.
足印图法常用于儿科足部疾病的识别和特征描述。然而，缺乏标准化的归一化方法给跨年龄比较带来了挑战。这项横断面研究提供了4至17岁正常发育儿童的足底压力规范数据，并比较了测量峰值和总负荷的参数的归一化及解释能力。
采用中步态协议，以自选速度测量了101名4至17岁正常发育儿童的动态足部压力。他们被分为五个年龄组：4至6岁、7至8岁、9至11岁、12至14岁和15至17岁。测量峰值和总负荷的力和压力变量通过体重进行归一化或按最大值进行缩放，并确定峰值压力出现的足部区域。
绝对值显示负荷随年龄增长而增加。相比之下，按体重归一化后，峰值压力和压力时间积分降低。缩放后的峰值压力显示负荷向前足转移。结果表明，归一化参数具有更高的定性意义，表明随着年龄增长，与体重相关的步态模式更具动态性，足部形态得到改善。
本研究表明，测量方案的标准化至关重要，因为正常发育儿童的结果可能因参数选择和归一化技术而异。
