["To assess the effect of an oral (O+O), a tactile/kinesthetic (T/K+T/K), and a combined (O+T/K) intervention on preterm infants' weight gain and motor function and to determine whether the combined O+T/K intervention has an additive/synergistic effect on outcomes.", 'Seventy-five preterm infants were randomized into an O+O intervention consisting of oral stimulation, a T/K+T/K intervention involving whole body stimulation, an O+T/K intervention, and a control group. Interventions were administered for 15 minutes, twice a day, for ten days.', 'Weight gain, motor function.', 'The O+O and T/K+T/K groups had greater weight gain during the intervention period than did controls (p ≤.025). The T/K+T/K and O+T/K groups had better motor function than did controls (p ≤.017).'] Do sensorimotor interventions improve growth and motor function in preterm infants?
