Socioeconomic categories
range from A (very high) to E (very low), and the remaining
are intermediate categories (B, C, D). For the study it was
found that categories A and B belonged to the high SES,
and categories C, D and E, to the low, according to the classification
adopted by Mancini et al(19). The final distribution
of the groups was as follows: children from high SES (mild,
moderate and severe CP) and children from low SES (mild,
moderate and severe CP).
