ABSTRACT
Development occurs in a proper rhythm as result of genetic inheritance and environment factors. This study had the aim to identify some environmental risk factors for the motor development in two groups of healthy children. 100 pre-school aged (five years children) from two day-care centers and a private school were evaluated, in Recife-PE. All the children underwent to a motor skills assessment and their parents answered a questionnaire. The children from the public nursery remained behind in fine motor skills. The results showed that the biologically healthy children development can suffer negative influence of the environmental risk factors. In this research these factors were: the father absence, improper toys use to the correct age, the place were the child was kept in the early childhood, the lack of pedagogical guidance and extra-parental socialization and low familiar socioeconomic status

No presente trabalho, foi investigado o efeito dos campos eletromagnéticos (CEM) näo ionizantes de extrema baixa frequência (ELF) e rádio-frequência (RF) sobre o desenvolvimento sensorial e motor em ratos neonatos. Ratos wistar foram expostos aos campos eletromagnéticos näo-ionizantes ELF, alternado,60Hz (n=24) e de RF,30MHz, burst de 55 Hz(n=30), no período de aleitamento (1§ ao 21§ dias pós-natais durante 30 minutos. O peso dos filhotes foram aferidos diariamente. foram diariamente observadas a maturaçäo dos reflexos (preensäo palmar, recuperaçäo de decúbito, colocaçäo pelas vibrissas, aversäo ao principío, resposta ao susto, geotaxia negativa, reaçäo de aceleraçäo) e a atividade locomotora no campo aberto nos 3§, 7§, 14§, 21§ dias pós-natais, quantificando o número de quadrados invadidos (NQI). A evoluçäo ponderal, a maturaçäo dos reflexos e o NQI dos grupos expostos aos CEM, comparados aos controles, näo sofreram alteraçöes. Estes resultados indicam que sob as condiçöes experimentais utilizadas, os campos eletromagnéticos näo alteram a expressäo comportamental de desenvolvimento sensório-motor
