Sequential changes in gait patterns were investigated retrospectively by analyzing the videotape recordings of 20 children with spastic diplegia and periventricular leukomalacia (PVL). The subjects began to walk at 1-5 years of age, and their walking was examined to 6-16 years of age. Many of the ambulatory children with spastic diplegia walked with flexed hips, knees and ankles. At the final walking examination, the knee was flexed during the stance phase in both legs and in all cases. In addition, the ankle was over-plantarflexed during the stance phase in nine cases or 14 legs, and dorsiflexed in 15 cases or 26 legs. At the initial walking, the knee was over-extended during the stance phase in seven cases or 12 legs, and was flexed in 15 cases or 28 legs. Also, the ankle was over-plantarflexed during the stance phase in 14 cases or 22 legs, and dorsiflexed in ten cases or 18 legs. Bilateral excessive ankle plantarflexion or a recurvatum knee was observed in a portion of the children at the initial phase of walking only. In the diplegic children with PVL, the gait pattern was variable.
通过分析20例痉挛型双侧瘫伴脑室周围白质软化症（PVL）患儿的录像记录，对步态模式的顺序变化进行了回顾性研究。这些受试者在1至5岁开始行走，并在6至16岁时接受行走检查。许多痉挛型双侧瘫的能行走儿童行走时髋、膝和踝关节呈屈曲状态。在最后一次行走检查时，双腿在站立期膝关节均呈屈曲状态，且所有病例均如此。此外，在站立期，9例（14条腿）踝关节过度跖屈，15例（26条腿）踝关节背屈。在开始行走时，7例（12条腿）在站立期膝关节过度伸展，15例（28条腿）膝关节屈曲。而且，在站立期，14例（22条腿）踝关节过度跖屈，10例（18条腿）踝关节背屈。仅在部分儿童行走初期观察到双侧踝关节过度跖屈或膝反张。在伴有PVL的双侧瘫患儿中，步态模式是多变的。
