The effect of M technique massage on behavioral state and weight gain in preterm neonates: a randomized controlled trial

This study aimed to investigate the effect of M technique massage on behavioral state and weight gain in preterm neonates admitted to neonatal intensive care unit (NICU). This was a randomized controlled trial study in which a total of 64 preterm neonates were randomly allocated to intervention and control group. Intervention group received M technique massage and control group received routine care. Neonatal weight and behavioral state were measured for two weeks. After intervention, no statistically significant difference was found between groups in terms of neonatal weight (mean difference: 44.03, 95% CI [‐180.66, 268.74]). At baseline, the mean score for behavioral state response was 5.84 ± 2.20 (mean ± SD) in control group and 5.68 ± 2.15 (mean ± SD) in intervention group and the difference was not significant (mean difference: 0.16, 95% CI [‐1.21, 1.52]), but 2 weeks later, and also, after intervention, a statistically significant difference was found between groups (mean difference: 2.16, 95% CI [1.19, 3.17]) and (mean difference: 3.03, 95% CI [2.15, 3.91]), respectively, meaning that it was significantly lower in intervention group compared with control group. According to the findings, massage with M technique in premature neonates can have a positive effect on behavioral state, but no effect on their weight gain.
