OBJECTIVE: To investigate the applicability of Near-Infrared Spectroscopy (NIRS) for
cortical hemodynamic assessment tool as an aid in the study of child development.
DATA SOURCE: Search was conducted in the PubMed and Lilacs databases using the following
keywords: ''psychomotor performance/child development/growth and
development/neurodevelopment/spectroscopy/near-infrared'' and their equivalents in
Portuguese and Spanish. The review was performed according to criteria established
by Cochrane and search was limited to 2003 to 2013. English, Portuguese and
Spanish were included in the search. DATA SYNTHESIS: Of the 484 articles, 19 were selected: 17 cross-sectional and two longitudinal
studies, published in non-Brazilian journals. The analyzed articles were grouped
in functional and non-functional studies of child development. Functional studies
addressed the object processing, social skills development, language and cognitive
development. Non-functional studies discussed the relationship between cerebral
oxygen saturation and neurological outcomes, and the comparison between the
cortical hemodynamic response of preterm and term newborns. CONCLUSIONS: NIRS has become an increasingly feasible alternative and a potentially useful
technique for studying functional activity of the infant brain.
