From: Cerebral oxygenation responses during kangaroo care in low birth weight infants
Behavioral states of infants observed before KC, in the middle of KC, at the end of KC, and 30 minutes after KC. The quiet sleep state was remarkably increased in the middle of KC and at the end of KC. A chi square test was performed to determine the significant differences in the four behavioral states.* p < 0.05, ** p < 0.01, before versus middle of KC or before versus end of KC.
