research overview

Dr. Bigsby's research focuses on the actions and facial expressions used by infants to signal their wants and needs to caregivers, and the relation between these behaviors and regulation of physiologic functions such as heart-rate and oxygen saturation. Other research interests include developmental interventions and outcomes for preterm infants in the NICU, feeding issues of early infancy, and the relation between early motor development and maternal life style.

research statement

Research involvement and publications reflect a long-standing interest in motor behavior of premature and other high-risk infants, particularly with regard to development of self-regulatory and feeding competencies and positive interaction with caregivers. An initial study of the presence of the aymmetrical tonic neck reflex, the attributes of stimulus objects and related patterns of reaching among preterm and full-term infants formed the foundation for a dynamical systems approach to development which could be woven into her clinical approach to infants at risk. For her doctoral dissertation work, Dr. Bigsby further explored dynamical processes by investigating the relation between motor behaviors and physiologic regulation among previously sick preterm and healthy term infants at 3 months corrected age. This work was continued within the clinical context of the neonatal intensive care unit (NICU) as a pilot project studying these same motor behaviors in the sick preterm population, and their relation to physiologic stability and positioning practices, through coding of videotaped observations of the infants before, during and after nursing care. She has coauthored a textbook on NICU interventions (Developmental and Therapeutic Interventions in the NICU - Brookes Publishing). Currently, she is collaborating with other NICU professionals on a study of the impact of the NICU environment on infant and caregiver behavior and development.

She is the coauthor of a tool for assessment of fine and gross motor development of high risk infants during the first year of life (Posture and Fine Motor Assessment of Infants (PFMAI) – Psychological Corp/Pearson), which involved Rasch analysis for scaling of items and forming criterion for norm referencing. She has acted as a consultant and trainer for the infant motor assessments used in the multi-site NIH funded "Maternal Lifestyles Study", including the PFMAI and the Peabody Scales of Motor Development, to demonstrate subtle differences between infants who have been exposed to illegal substances in-utero and those who have not. She also has participated in the development of clinical applications for the Neonatal Network Neurobehavioral Scale (NNNS). Dr. Bigsby has mentored graduate students in their study of preterm infant behavior, and the relation between infant sensory and feeding issues, and is currently working with a multi-disciplinary group of professionals in the NICU to develop an approach to initiating and progressing breast and bottle feeding in the NICU.
