Effects of hydrotherapy and tactile-kinesthetic stimulation on weight gain of preterm infants admitted in the Neonatal Intensive Care Unit

The present study aimed to evaluate the effects of hydrotherapy and tactile-kinesthetic stimulation on the birth weight of preterm infants admitted in the Neonatal Intensive Care Unit.It was a randomized controlled trial, without blinding, in which 44 preterm infants of both sexes with gestational age between 32 and 34 weeks were included into two groups: hydrotherapy group (n = = 22) and tactile-kinesthetic stimulation group (n = 22). Weight gain was the parameter assessed daily.In the tactile-kinesthetic stimulation group there was a variation in weight gain, but without significant difference (p = 0,43). However, in the hydrotherapy group, it was observed that increased weight gain started from the 2nd day (p < 0,001).Hydrotherapy group presented significantly increased weight after the interventions, indicating that this technique can interfere with weight gain in preterm infants.
