Abstract/OtherAbstract:
Background and Objective:Daily experiences are thought to play an important role in motor development during infancy. There are limited studies on the effect of postural and movement experiences on head control. The purpose of this study was to quantify the effects of postural and movement experiences on head control through a comprehensive set of measurements beginning when infants were one month old.Design:This is a prospective, longitudinal, two-cohort study. METHODS:22 healthy full-term infants were randomly assigned to the Control (CG) or Training (TG) groups. Infants were observed every other week from 1 to 4 months old. Head control was assessed using a standardized developmental assessment tool, the TIMP, as well as behavioral coding and kinematics of infants' head posture and movements in supported sitting. Caregivers performed at least 20 minutes of daily posture and movement activities (TG), or social interaction (CG) for 4 weeks. RESULTS: TG infants had higher TIMP scores of head control related items during the training period and after training stopped, compared to CG infants. Starting from the During Training phase, TG infants had their heads in a vertical and midline position longer, compared to CG infants. After training stopped, TG infants actively moved their heads forward more often and for larger distance.Limitations:The experiences outside daily training were not monitored and the results may be specific to the experimental set up for infants with typical development. CONCLUSIONS:Young infants are able to take advantage of postural and movement experiences to rapidly advance their head control as early as 4 to 6 weeks of postnatal life. Infant positioning, caregiver handling and caregiver-infant interactions were likely contributing factors. This database of comprehensive measures may be useful in future trials focused on head control in infants with special needs.
