Abstract This is a descriptive, longitudinal study, with a convenience sample of an applied nature, developed from February to December of 2018, and aiming of verify whether a specific training, a series of varied and short-term practice conditions, influence the behavior of manual reach and skill retention in preterm infants with low birth weight. Six infants of both genders participated, randomly divided into: experimental group, which received specific training; and control group, which received only social interaction. 180 ranges of both groups were analyzed. Although without statistically significant difference, but with clinical relevance, the results showed that specific training promoted an improvement in the total frequency of the reach (d = 0.88, 95% CI), and, in distal adjustments of reach (oblique and semi-open hand), in the experimental group in relation to the control group. In the kinematic parameters of range, the results showed a more organized range, indicating that something was learned and/or changed in the period immediately after training, however, learning retention was not verified. Thus, it is believed that more prolonged training is necessary to obtain learning retention.This is a descriptive, longitudinal study, with a convenience sample of an applied nature, developed from February to December of 2018, and aiming of verify whether a specific training, a series of varied and short-term practice conditions, influence the behavior of manual reach and skill retention in preterm infants with low birth weight.
