Use of oscillating waterbeds and rhythmic sounds for premature infant stimulation.

22 healthy infants born at gestational ages of 28–32 wks were randomly assigned to experimental or control groups within the 1st 4 days following birth. Experimental Ss were placed in incubators equipped with oscillating waterbeds and rhythmic sounds; control Ss were placed in traditional incubators. Results indicate that general developmental progress was enhanced in the experimental group by the stimulation procedure. (22 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
