Leg movements in the supine position of 49 infants with spastic diplegia (three to 11 months corrected age) were examined. Only simultaneous flexion and extension of the hips and knees were seen, with exceptional isolated hip movements; the simultaneous movements had synergic features. When the knees were flexed, the hips were flexed, abducted and externally rotated, and the ankles were dorsiflexed. When the knees were extended, the hips were extended, adducted and internally rotated and the ankles were plantar-flexed. Hip flexion combined with knee extension (leg elevation) and isolated knee movements were not seen in diplegic infants, but were seen in all control preterm infants with a good prognosis, after five and six months corrected age, respectively. The absence of these movements is a useful diagnostic item for spastic diplegia.
对49例痉挛型双瘫婴儿（矫正年龄3至11个月）仰卧位时的腿部运动进行了检查。仅观察到髋部和膝部同时的屈伸动作，偶有孤立的髋部动作；同时动作具有协同特征。当膝关节屈曲时，髋关节屈曲、外展并外旋，踝关节背屈。当膝关节伸展时，髋关节伸展、内收并内旋，踝关节跖屈。双瘫婴儿未见髋部屈曲伴膝关节伸展（腿部抬高）及孤立的膝关节动作，但在所有预后良好的对照早产儿中分别在矫正年龄5个月和6个月后可见到。这些动作的缺失是痉挛型双瘫的一项有用诊断指标。
