Individuals with cerebral palsy (CP) usually suffer from different impairments including gait impairment and spasticity. Spastic hypertonia is a defining feature of spasticity and manifests as a mechanical abnormality. The objective of this study was to determine the relationship between spastic hypertonia and gait impairments in spastic children with CP, addressing an important controversial issue. Spastic hypertonia was quantified using the pendulum test. The gait impairments were evaluated using the motion capture system in a gait laboratory. Our results showed significant correlations among gait parameters; i.e. walking speed, step length, and the pendulum test measures. This indicates that neuromuscular abnormalities are associated with spasticity and may contribute to gait impairments. The clinical implication is that the impaired gait in children with CP may be improved with the treatment of neuromuscular abnormalities.
患有脑瘫（CP）的个体通常会遭受包括步态障碍和痉挛在内的不同损伤。痉挛性张力亢进是痉挛的一个决定性特征，表现为一种机械性异常。本研究的目的是确定痉挛性张力亢进与痉挛型脑瘫患儿步态障碍之间的关系，以解决一个重要的争议问题。使用摆锤试验对痉挛性张力亢进进行量化。在步态实验室中使用运动捕捉系统评估步态障碍。我们的结果显示步态参数之间存在显著相关性；即步行速度、步长和摆锤试验测量值。这表明神经肌肉异常与痉挛有关，可能导致步态障碍。临床意义在于，通过治疗神经肌肉异常，脑瘫患儿受损的步态可能会得到改善。
