Investigating of the effects of mother's voice on physiological responses in premature infants

Despite significant advances in medicine and survival rates of premature infants, the infants also suffer from neurological disability and abnormal growth. Based on theories, supportive care of premature infants on growth and development and function of neural-behavioral therapy was effective and provided by certain types of stimuli. This study aimed to investigate the effect of mother's voice on physiological responses in premature infants.

Collected data using SPSS 19 statistical software will be calculated.
In this study, infants with gestational age 36-30 weeks. Boys are born with less weight. Weight inclusion in boys is more than the girls in the control group opposed to this. Apgar score at birth do not differ in terms of male and female infants. Physiological responses between males and females has decreased after the intervention.
The results of this study showed that both the mother's voice sounds strange woman and physiological responses of preterm infants who have a positive impact (P
