Inclusion Criteria

Twenty healthy full-term infants free from neurological or musculoeskeletal pathologies, with gestational age between 37 and 40 weeks, birth weight higher than 2.500 g, Apgar in the first minute higher than 7 and in the fifth minute higher than 9.
Twenty healthy pre-term infants free from neurological or musculoeskeletal pathologies, with gestational age between 30 and 36 weeks, birth weight adequated for gestational age, Apgar in the first minute highter than 7 and in the fifth minute higher than 9.
These convenience sample will be selected based on maternity medical records information.

Exclusion Criteria

1) congenital defects in the central nervous system (anencephaly, spina bifida, micro / macrocephaly, hydrocephalus, among others);
2) signs of neurological damage (hypoxic-ischemic encephalopathy grades: I, II and III, intracranial hemorrhage, neonatal seizures, spasticity, abnormalities in
reflexes and hypotonia), and 3) musculoskeletal (congenital torticollis, arthrogryposis multiplex, achondroplasia), 4) diagnostic of genetic syndromes (Down syndrome or any syndrome deletion chromosome) or symptoms of withdrawal symptoms associated with maternal report of abuse of alcohol and drugs, 5) congenital infections (toxoplasmosis, rubella, cytomegalovirus, syphilis,
humam imunodeficiency virus (HIV), hepatitis A, B or C) reported by mothers whose serology, as described in the handbook
motherhood, is positive, 6) have sensory deficits (auditory and visual), detected by thorough pediatric examination performed after the birth at the Maternity and signs of retinopathy of prematurity, grade: II and III, 7) cardio-respiratory problems, 8) hyaline membrane syndrome, sepsis or whose mothers have submitted episode
pre-eclampsia or eclampsia. Will be excluded infants who do not attend for the first evaluation on the given date.

Primary Outcome Measures

Name	Time	Method
median angular velocity of head movement measured by kinematical analysis and Matlab software.[monthly, and in each condition, from 1 to 4 months in fulltem infants and from 1 to 4 months of corrected age for pre-term infants];range of motion (flexion extension, inclination and rotation) of head movement, measure by kinematica analysis and Matlab software.[monthly, and in each condition, from 1 to 4 months in fulltem infants and from 1 to 4 months of corrected age for pre-term infants]

Secondary Outcome Measures

Name	Time	Method
frequency of head movement, measured by watching the images recorded during assessment by three video cameras. These images will be watched in Dvideo software for kinematical analysis, after assessment.[monthly, and in each condition, from 1 to 4 months in fulltem infants and from 1 to 4 months of corrected age for pre-term infants, by quantification of frequencies observed when watching the images recorded, afer assessment. On pre-term infants, the assessment will occur in corrected ages of 1, 2, 3 e 4 months.]
