Pedaling smoothness and electromyography patterns were quantified in children with spastic diplegic cerebral palsy (CP) and a cohort of children with typical development. Video analysis of the pedaling rhythm yielded equivalent time periods for the control group and irregular time periods in the group with CP, with greater time spent at the bottom of the pedaling cycle. Electromyography patterns of the tibialis anterior, rectus femoris, medial hamstring and lateral gastrocnemius muscle groups yielded greater percentages of muscle activity time and co-contraction time at both the ankle and knee in the group with CP; however, the control group had longer ankle co-contraction times than were expected from previous adult studies.
对痉挛性双侧瘫脑瘫患儿和一组发育正常儿童的蹬踏流畅性和肌电图模式进行了量化。对蹬踏节奏的视频分析显示，对照组的时间周期相等，而脑瘫组的时间周期不规则，且在蹬踏周期底部花费的时间更长。胫前肌、股直肌、半腱肌内侧头和腓肠肌外侧头肌群的肌电图模式显示，脑瘫组在踝关节和膝关节处的肌肉活动时间和共同收缩时间百分比更高；然而，对照组的踝关节共同收缩时间比以往成人研究预期的要长。
