Ankle-foot orthoses (AFOs) are prescribed to children with cerebral palsy (CP) in hopes of improving their gait and gross motor activities. The purpose of this retrospective study was to examine if clinically significant changes in gross motor function occur with the use of AFOs in children and adolescents diagnosed with CP (Gross Motor Function Classification System levels I and II). Data from 124 clinical assessments were analyzed. Based on minimum clinically important difference (MCID), 77% of subjects demonstrated an increase in stride length, 45% of subjects demonstrated an increase in walking velocity, and 30% demonstrated a decrease in cadence. Additionally, 27% of the subjects demonstrated increase in gait deviation index (GDI). Deterioration in gait was evident by decreases in walking speed (5% of subjects), increases in cadence (11% of subjects), and 15% of subjects demonstrated decreases in gait deviation index. Twenty-two percent of subjects demonstrated no change in stride lengths and one participant demonstrated a decrease in stride length. However, AFOs improved Gross Motor Function Measure (GMFM) scores for a minority (10%) of children with mild CP (GMFCS level I and II), with 82-85% of subjects demonstrating no change in GMFM scores and 5-7% demonstrating decrease in GMFM scores.
踝足矫形器 (AFO) 被开给脑瘫 (CP) 儿童，希望能改善他们的步态和粗大运动活动。本回顾性研究的目的是检查在 CP 诊断的儿童和青少年中使用 AFO 是否会导致粗大运动功能出现临床显著变化（粗大运动功能分类系统水平 I 和 II）。对 124 项临床评估的数据进行了分析。基于最小临床重要差异 (MCID)，77%的受试者步长增加，45%的受试者行走速度增加，30%的受试者步频减少。此外，30%的受试者的步态偏差指数 (GDI) 增加。步态恶化表现为行走速度下降（5%的受试者）、步频增加（11%的受试者）和步态偏差指数下降（15%的受试者）。22%的受试者步长没有变化，一名受试者步长下降。然而，AFO 改善了轻度 CP（GMFCS 水平 I 和 II）患儿中少数（10%）的粗大运动功能测量 (GMFM) 评分，82-85%的患儿 GMFM 评分没有变化，5-7%的患儿 GMFM 评分下降。
