Reaching skills in six-month-old infants at environmental and biological risk.

<h4>Objectives</h4>To assess kinematic parameters and proximal and distal reaching adjustments of infants at biological or environmental risk and compare with reaching performance of six-month-old full-term infants without known risk factors.<h4>Methods</h4>This blinded cross...

Infants were placed in a reclined baby chair at 45°, and a malleable and unfamiliar object was presented to the infant at 5-second intervals to elicit reaching movements.<h4>Results</h4>Infants from LSES presented reaching duration (p = 0.032, Cohen's f = 0.349) and movement unit (p = 0.033, Cohen's f = 0.351) significantly higher than VPT group. Horizontal hand orientation was moderately associated with infants at environmental risk (p = 0.031; Cramer's V = 0.30).<h4>Conclusion</h4>Infants of low socioeconomic status perform less functional reaching movements than very preterm infants at six months corrected age.
