The neurologic prognoses in infants whose ankle clonus was more than ten beats at any age within the first year of life, and ten or less beats over 8 months of age were always abnormal. In the subjects whose neurologic signs other than ankle clonus appeared within 4 months of age and persisted after 5 months of age, prognoses were generally poor.
