ABSTRACT

Purpose

To identify changes in the gait kinematics and temporospatial parameters of children with bilateral Cerebral Palsy (CP) at 8 months after the onset of independent walking and identify differences to Typical Development (TD) children at the onset of independent walking and at 8 months follow up.

Method

Sixteen children with bilateral CP, GMFCS levels I and II, and 15 TD children were recruited. Gait kinematics and temporospatial parameters were recorded using a 3-D gait analysis system; the sagittal plane of the lower limb joints was analyzed. Baseline measurements were recorded at the individual’s onset of independent walking and follow up was after 8 months.

Results

Compared to baseline, children with bilateral CP demonstrated increased (mean difference ± SE) plantar flexion (11.79 ± 2.96), single support (0.04 ± 0.01), step length (0.2 ± 0.05) and stride length (0.4 ± 0.09), at follow up; all p < .05. Compared to TD children, they also had lower gait speed (0.16 ± 0.05), higher single support (0.02 ± 0.01) and lower maximum knee extension (9.14 ± 4.49) during the swing phase, at baseline and follow up (0.1 ± 0.04, 0.05 ± 0.01, 23.04 ± 4.17, respectively); all p < .05.

Conclusion

There are changes in the sagittal plane kinematics and temporospatial parameters of the gait during the first 8 months of independent walking. These indicate gait maturation changes and highlight the impact of walking experience on the gait characteristics of children with bilateral CP.

脑瘫患儿步态发展初期的运动学和时空变化

摘要

目的

识别双侧脑瘫 (CP) 儿童在独立行走后 8 个月时步态运动学和时空参数的变化，并确定独立行走开始时和 8 个月随访时与典型发育 (TD) 儿童的差异.

方法

招募了 16 名双侧 CP、GMFCS I 和 II 级儿童和 15 名 TD 儿童。使用 3-D 步态分析系统记录步态运动学和时空参数；分析下肢关节的矢状面。在个体开始独立行走时记录基线测量值，并在 8 个月后进行随访。

结果

与基线相比，双侧 CP 患儿的跖屈 (11.79 ± 2.96)、单支撑 (0.04 ± 0.01)、步长 (0.2 ± 0.05) 和步幅 (0.4 ± 0.09) 增加（平均差 ± SE）向上; 所有p < .05。与 TD 儿童相比，他们在摆动阶段、基线和随访中的步态速度（0.16 ± 0.05）、单支撑更高（0.02 ± 0.01）和最大膝关节伸展（9.14 ± 4.49）更低（0.1 ± 0.04，分别为 0.05 ± 0.01、23.04 ± 4.17）；所有p < .05。

结论

在独立行走的前 8 个月中，步态的矢状面运动学和时空参数发生了变化。这些表明步态成熟的变化，并突出了步行经验对双侧 CP 儿童步态特征的影响。
