PURPOSE: This study is aimed to confirm the effects of Yakson therapy on the growth and physical response of preterm infants, and maternal attachment to them compared with GHT therapy. METHOD: The design of this study is nonequivalent control group with repeated measuring by quasi experimental study. The subjects are preterm infants in 26 - 34 gestational age hospitalized in the NICU of 4 university hospitals with an experimental group of 15 and a control group of 14. Yakson therapy consists of three phases: laying a hand, caressing by hand, and laying a hand again taking 5 minutes for each phase. RESULT: As a result of administering Yakson therapy to preterm infants; the average weight gain of the Yakson group was higher than that of the GHT group, but there is no significant difference between groups. The oxygen saturation and maternal attachment difference between the Yakson and the GHT group were not significant. Significant differences in the average daily increase of oral intake and apical pulse rate were observed between the Yakson group and GHT group. CONCLUSION: These data suggested that Yakson therapy may be an effective nursing intervention which can facilitate growth and physical response of preterm infants.
