Recent research on the PlagioCradle™ device demonstrates prevention and correction of DP in hospitalized infants. However, extremely premature infants, weighing < 1 kilogram cannot use the device known as the PlagioCradle™. This device only accommodates infants weighing > 1 kilogram. When infants eventually reach 1 kilogram, healthcare providers have trouble fitting them to the smallest version of the PlagioCradle™ device and must place the infant in a layer meant for a larger infant. Use of the larger layer often requires that infants' lay in a side-lying position until their head shapes begin to improve. It is more desirable that infants be placed in the appropriate layer so that they may be positioned supine, prone, side-lying left and right, to ensure optimal development. This pilot project proposes to develop and test a new device to manage (defined as resolving, prohibiting, inhibiting or preventing) the development of DP in prematurely born infants weighing < 1 kilogram.
