Abstract

To determine when the plantar response becomes reliably flexor in infants, 169 infants underwent serial evaluation from 2 weeks to 12 months of age during routine well-child visits. The plantar response, elicited in a standardized fashion, was extensor in 95.5%, 64.8%, 10.9%, 0.7%, and 0% of the infants at 2, 4, 6, 9, and 12 months, respectively. The plantar response becomes predominately flexor by 6 months of age in normal infants. This maturation of response correlates closely with that of other infantile reflexes.

摘要

为了确定婴儿足底反射何时能稳定地表现为屈肌反应，169名婴儿在常规健康儿童检查期间，从2周龄至12月龄接受了系列评估。以标准化方式引出的足底反射，在2、4、6、9和12月龄婴儿中分别有95.5%、64.8%、10.9%、0.7%和0%表现为伸肌反应。正常婴儿在6月龄时足底反射主要表现为屈肌反应。这种反应的成熟与其他婴儿反射的成熟密切相关。
