Cerebral palsy (CP) is a common cause of motor disability, and pedobarography is a useful, non-invasive, portable, and accessible tool; is easy to use in a clinical setting; and can provide plenty of information about foot-soil interaction and gait deviations. The reliability of this method in children with CP is lacking. The aim of this study is to investigate test-retest reliability and minimal detectable change (MDC) of plantar pressure insole variables in children with CP. Eight children performed two trials 8 ± 2.5 days apart, using foot insoles to collect plantar pressure data. Whole and segmented foot measurements were analyzed using intraclass correlation coefficients (ICC). The variability of the data was measured by calculating the standard error of measurement (SEM) and the MDC/ICC values demonstrated high test-retest reliability for most variables, ranging from good to excellent (ICC ≥ 0.60). The SEM and the MDC values were considered low for the different variables. The variability observed between sessions may be attributed to the heterogeneous sub-diagnosis of CP.
脑性瘫痪（CP）是一种常见的运动障碍，足底压力测量是一种有用的、非侵入性的、便携的和易于使用的工具；在临床环境中易于使用；并能提供大量关于足与地面相互作用和步态偏差的信息。该方法在 CP 儿童中的可靠性尚不清楚。本研究旨在探讨 CP 儿童足底压力鞋垫变量的测试-重测信度和最小可检测变化（MDC）。8 名儿童在 8 ± 2.5 天的时间间隔内进行了两次试验，使用足底鞋垫收集足底压力数据。使用组内相关系数（ICC）分析全足和分段足测量值。通过计算测量标准误差（SEM）来衡量数据的变异性，MDC/ICC 值表明大多数变量的测试-重测信度较高，范围从良好到优秀（ICC ≥ 0.60）。不同变量的 SEM 和 MDC 值较低。两次测试之间的可变性可能归因于 CP 的亚诊断异质性。
