To compare quantity and quality of spontaneous leg movements during early infancy in babies with myelomeningocele (MMC) and babies with typical development (TD).
Nine infants with MMC and 12 with TD moved spontaneously while supine for 5 minutes at ages 1, 3, and 6 months. We used a 6-camera system to monitor leg movements. Resultant leg displacement and velocity were used to determine movement frequency and, for each movement, duration, distance, peak velocity, jerk, and number of acceleration peaks.
Movements of infants with MMC were shorter in duration with fewer acceleration peaks than their peers. Asymmetrical interlimb frequencies in infants with TD resulted in one leg moving more than the other, which was similar to the lower symmetrical interlimb frequencies of infants with MMC.
Infants with MMC show depressed movement activity. Further research is needed to determine if therapy can facilitate spontaneous activity and leg control.
比较脊髓脊膜膨出（MMC）患儿与正常发育（TD）婴儿在婴儿早期自发腿部运动的数量和质量。
9名MMC患儿和12名TD患儿在1、3和6个月大时仰卧位自发运动5分钟。我们使用一个6摄像头系统监测腿部运动。腿部位移和速度用于确定运动频率，以及每次运动的持续时间、距离、峰值速度、加加速度和加速度峰值数量。
MMC患儿的运动持续时间较短，加速度峰值较少，比同龄儿童少。TD患儿的不对称肢体间频率导致一条腿比另一条腿运动更多，这与MMC患儿较低的对称肢体间频率相似。
MMC患儿的运动活动减少。需要进一步研究以确定治疗是否可以促进自发活动和腿部控制。
