[Incidence of minimal cerebral palsy among students in elementary schools and special schools for speech disorders]

Minimal cerebral palsy (min. CP) can be diagnosed by a motoscopic neurological procedure. Two groups were tested: 1) 402 second year pupils of elementary school, aged 7; 6 to 8; 6 years, 2) 192 pupils of a special school for children with speech disturbances, preschool groups and pupils from the 1st to the 4th year of elementary school. Among the first group (n = 402) a frequency of 9.5% for min. CP was found. 17.7% were border line cases, 72.9% normal. Teachers asked to point out children with obvious motor disability identified 89.4% of the cases with min. CP; but considered only 9.8% of the neurologically normal children as having motor dysfunction. In the second group (n = 192) min. CP was found in 21.3%. The highest percentage was found in preschool classes: 63.1%.
