RESUMO

Introduction: Early intervention and parental education for preemies are limited in some low-income countries. Thus, this study aimed to assess whether daily tummy time (TT) associated with usual care (UC) enhances motor and cognitive development in preemies from low-income countries. The main and secondary aim was to assess prone head elevation (PHE) and motor and cognitive functions, respectively. Methods: Thirty-one preemies with a mean gestational age at birth of 33.3 ± 1.6 weeks and weighing <2,500 g were included and 18 completed all assessments. Parents from the TT group were asked to perform TT with their preemies for at least 20 min during daily activities and playtime. Motor and cognitive functions were assessed by a blinded examiner using the motor and cognitive composite scores of Bayley-III after two and four months of corrected age. PHE was given by the angle from the tragus of the ear to the supporting surface of the infant; measurements were obtained using the Kinovea® software at baseline, after two, three, and four months of corrected age. Results: The Bayley-III motor composite score of the TT group was higher than the UC group after two and four months of corrected age. The PHE angle increased over time but did not differ between groups. Discussion: Nevertheless, TT expanded the perspective of preemies to explore their bodies and environment, favoring the stimuli for motor and cognitive patterns. The loss of participants (31%) was one of the limitations of the study, illustrating the challenge of providing continued early interventions to preemies from low-income countries. In this sense, TT practice is a home intervention that may improve motor and cognitive function of preemies immediately after hospital discharge.

RESUMO

PURPOSE: The primary aim will be to assess the effects of prone positioning (tummy time) on cervical extension (angular kinematics and time) in preterm infants. The secondary aim will be to assess the effects of tummy time on gross motor function. METHODS: This randomized, controlled clinical trial will include 40 preterm infants weighing less than 2500 g, randomly allocated into control or experimental group (n = 20) and followed up from birth to six months of corrected age by the team of the neonatal follow-up clinic. Caregivers will be routinely guided on bonding, developmental milestones, and how to perform the tummy time for 30 min throughout the day (experimental group). An illustrative booklet will be provided as support material. The hypothesis will be tested using inferential analysis, considering an alpha of 5%. DISCUSSION: We expect tummy time to strengthen cervical muscles needed to overcome gravity, master motor skills, and stimulate the integration between family activity and environmental experiences, considerable challenges to which preterm infants are exposed. TRIAL REGISTRATION: Registered in the Brazilian Registry of Clinical Trials (identifier RBR-2nwkr47) on 17 February 2022.
