Status Recruiting

Clinical Trial Summary

Cerebral palsy and other neuromotor disorders are more common in babies born preterm (<37 weeks of gestation), due to various biological and environmental risk factors and the risk increases as the gestational age decreases. Earlier and more frequent screening with the use of developmental skills tests facilitates referral to early intervention programs. Current guidelines recommend using some combination of neuroimaging and neurological examination and assessments such as neonatal imaging, general movements (GMs), and Hammersmith Infant Neurological Examination (HINE) for early diagnosis and intervention.

Clinical Trial Description

The aim of study was to evaluate the risk of premature and low birth weight babies with the Early Infant Motor Evaluation Test (STEP), to measure the correlation of the STEP test with Bayley Infant Development Scales (Bayley-III) and Hammersmith Infant Neurological Examination (HINE) evaluations, to investigate the validity and reliability of the STEP test in the evaluation and follow-up of babies at risk. The Early Infant Motor Evaluation Test (STEP) provides a quantitative assessment of tone and movements that allows developmental monitoring with a short screening test in terms of practical patient flow. A standardized test provides an opportunity to recognize early abnormalities in tone and movement patterns and seek treatment before milestones are delayed or abnormal movements stabilized. STEP can be used to measure early movement problems in high-risk infants, refer these infants earlier, and then monitor response to targeted interventions. It is thought that STEP can identify infants at risk of delay, thus enabling earlier initiation of targeted therapy. The implementation and scoring of STEP takes approximately 10 minutes. It does not require special training, is easy to access, is a short and fast performing neuromotor examination. As a screening test for early intervention, it can be applied in neonatal intensive care units and follow-up clinics prior to discharge, potentially improving long-term outcomes. Technological advances in neonatal-perinatal medicine have led to a steady increase in the survival rate of preterm infants. Although the increase in survival rate has been a remarkable achievement, children born prematurely are at high risk for brain damage and long-term neurodevelopmental deficits. Premature children may have abnormal muscle tone or movements, cognitive deficits, language disorders, and behavioral problems. Babies born preterm (<37 weeks of gestation) are three to four times more at risk for a range of motor disorders than the general population due to various biological and environmental risk factors. This highlights the need for improved surveillance and intervention strategies in this group of children. The main goal of developmental surveillance in infants with risk factors for cerebral palsy and other neuromotor disorders is to screen for signs of delayed motor development so that physical therapy can be started as early as possible. Neuroimaging is expensive and does not detect all infants at high risk. Parental reporting of motor milestones in the first trimester is unlikely to be as accurate as methods based on direct observation. Barriers to implementing highly sensitive assessments based on direct observation include the cost of training, lack of reliability in various professions, and the duration of assessment. Most of the screening tests used involve long-term use that may harm newborns. Accurate assessment of motor performance in infants born prematurely or with other perinatal complications requires the use of validated tests to identify delay or neurological impairment. Documenting the construct validity of a new assessment requires research that demonstrates its relevance to other tests available for similar purposes. Recent studies also advocate the use of a combination of assessment tools in the first year of life. Studies have proven that the use of a combination of standard neurologic and motor assessments for early diagnosis and intervention in the evaluation of at-risk infants is more effective. It is known that the STEP test does not require certification training and whose reliability is valid, does not have a Turkish version.In this thesis, the validity and reliability of the Early Infant Motor Evaluation Test (STEP) will be investigated, and its correlation with the Hammersmith Infant Neurological Examination (HINE) and Bayley Infant Development Scales (Bayley-III) evaluation will be evaluated. The translation of the scale into Turkish will be carried out separately by two health professionals who are fluent in the original language and medical terminology. The final version of the scale will be translated back from the target language to the original language by a sworn translator who has no knowledge of the subject, and the back translation will be compared with the original questionnaire. Medical records and demographic data of the patients whose verbal and written consents were obtained will be obtained and STEP test will be applied at term age and at 3 months, with HINE test at corrected 3 months and 6 months and Bayley III test at corrected 6 month. ;
