ABSTRACT This study aimed to verify the applicability of the Test of Infant Motor Performance (TIMP) in surgical neonates as a tool for evaluating motor performance and to evaluate the benefit of physical therapy. Surgical neonates, divided into group without physical therapy (n=38) and group with motor physical therapy (n=38), were evaluated by TIMP and reasssment two weeks later. The physical therapy group performed standardized exercises for motor sensory stimulation once a day, whereas the other group received the usual care from the Neonatal Intensive Care Unit. The predominant surgical diagnosis in both groups was gastroschisis, followed by congenital diaphragmatic hernia. In the initial evaluation, motor performance was equal between the groups, classified as “below average” for age, with z-score=−1.28 (p=0.992). In the reassessment, the physical therapy group presented better scores (p<0.001) and a higher difference in z-score (p<0.001), higher percentage of neonates classified as “within average” (44% in the physical therapy group and 2.6% in the no physical therapy group), as well as a higher weight gain percentage (p=0.038). We found a worsening of motor performance in 10.5% of the no physical therapy group (p<0.001) in the reassment. Motor performance improved in 81.6% of the physical therapy group and in only 13.2% of the no physical therapy group individuals (p<0.001). Conclusion: TIMP was safely and effectively applied to newborns; notably, the test must be performed by professionals experienced in care of neonates. Motor intervention was beneficial, significantly improving motor performance, and if applied early, it may adequate the motor development of these neonates, even before hospital discharge.
