Purpose: This study is aimed to confirm the effects of Yakson therapy on the growth and physical response of preform 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 preform 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 preform infants.

Purpose: The purpose of this study was to identify the effects of Yakson therapy as a pain management tool oil the physiologic and behavioral reponses of infants with a painful heelstick procedure. Method: Infants were randomly assigned to a group that underwent a series of Yakson therapy and a control that received nothing before a heelstick. Heart rate, oxygen saturation, and NIPS were compared between the experimental (n=16) and control (n=16) infants during an undisturbed baseline and after a standard heelstick procedure Yakson therapy consisted of laying a hand on the back, and caressing the abdomen by hand for 5 minutes. Result: The pain scores of the Yakson group were lower than the control group. Foroxygen saturation, there were statistically significant differences between groups. For heart rate, there were no statistically significant differences between groups. Conclusion: This data suggests that Yakson therapy had a pain relief effect in behavior responses and $SaO_2$. Accordingly, Yakson therapy should be used as a nursing intervention for simple pain management for a heel prick.

Purpose:　The purpose of this study was to investigate the effects of Yakson therapy conducted by mother of preterm infants on the maternal attachment and attachment behavior. Method: A quasi experimental pre-post test design was used. The data were collected from January, 2005 to October, 2005. The participants were 30 mothers of preterm infants hospitalized in a neonatal intensive care unit (15 in the Yakson therapy group and 15 in control group). Yakson therapy consists of three phases: laying a hand, caressing by hand, and laying a hand again taking 5 minutes for each phase. Yakson therapy was provided to infants in the experimental group for 15-minutes 5 times for 15 days. Data were analyzed using the SAS program with x2-test, repeated measures ANOVA, and Fisher's exact test. Result: Compared to the control group, the experimental group had significantly higher scores in maternal attachment (F=5.54, p=.0258). And the attachment behavior of the experimental group was higher than that of the control group. Conclusion: The results suggest that Yakson therapy can be used to improve maternal attachment and attachment behavior.

Purpose: The purpose of this study was to investigate the effects on weight of premature infants when Yakson therapy was conducted by mothers and also to measure role confidence and role satisfaction of the mothers. Method: A non-equivalent control group non-synchronized design was used. The data were collected from January to July, 2005. Thirty preform infants and mothers were assigned to either an experimental (15) or a control group (15). Yakson therapy consists of three phases: laying on of hands, caressing by hands, and laying on of hands again, each phase taking 5 minutes. Yakson therapy was provided to infants in the experimental group for 15-minutes 5 times a day far 15 days. Infant weight, mothers' role confidence and satisfaction with role were measured for both groups. Results: Compared to the control group, weight gain of infants in the experimental group (t=2.05, p=.049) was significantly increased after 15 days. The experimental group also had significantly higher scores in mothers'.ole confidence (t=1.98, p=.038). Conclusion: The results suggest that Yakson therapy can be used to increase weight gain in preform infants and improve the role confidence of mothers.
