Brief summary
High risk infant is defined as infant with a negative history of environmental and biological factors, which can lead to neuromotor development problems. It is a heterogeneous group of premature infants born under thirty-seven weeks of age, with infants with low birth weight, term or developmental retardation for various reasons. Therefore, preterm infants with low birth weight can survive with a neurological sequelae such as cerebral palsy (CP), epilepsy, hearing and vision loss, mental retardation, speech and speech problems, and learning difficulties. The clinical diagnosis of CP and learning diffuculties which can be observed in high-risk infants, is based on the combination of some neurological and clinical signs.
Detailed description
High-risk of infant follow-up programs provide guidance for the treatment of neurodevelopmental delays and deterioration in terms of early development. Three methods with the best predictable validity that can determine CP before the adjusted age of 5-month is Magnetic Resonance Imaging (MRI), Prechtl's Assessment of General Movements (GMs), Hammersmith Infant Neurological Evaluation. In recent years, the diagnosis of high-risk of CP can be detected at 3 months with predictive validity and reliability by evaluating the quality of GMs. GMs are now considered the gold standard for early detection of CP because of its high sensitivity and specificity than MRI, cranial US and neurological evaluations. It was also found that cognitive or language skills may be inadequate in school age in patients with inadequate movement character and in the same postural patterns according to age, although GMs are normal. So new clinical care guidelines and new intervention research for infants with CP and learning diffuculties under the age of 1, needs to be been shown. There a few studies about early detection of learning diffuculties like autism spectrum disorders between GMs and cognitive development tests. So this study aimed to reveal the association between GMs and cogtinive development with a cohort of high risk of infants with one year floow up.
Interventions
OTHERmeasurements
All of the infants with high risk of cerebral palsy will be assessed from birth to 12 months age with the assessments of Prechtl's General movements (GMs) until 20 weeks of age. Also BAYLEY-III Infant and Toddler Development Assessment Scale (BAYLEY-III) will be performed at the 3rd, 6th, and 12th months for the cognitive development.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Prechtl's General movements (GMs) assessments1 | Measurement at preterm age (birth to 40weeks) | General movements (GMs) are the spontaneous movement repertoire present from early foetal life until 20 weeks post-term. From birth to 8 post-term weeks, they have a writhing character. They will be scored as cs-pr-n-ch. N show normal movement patterns. |
| Prechtl's General movements (GMs) assessments2 | Measurement between the term age to 9th weeks | General movements (GMs) are the spontaneous movement repertoire present from early foetal life until 20 weeks post-term. From birth to 8 post-term weeks, they have a writhing character. They will be scored as cs-pr-n-ch. N show normal movement patterns. |
| Prechtl's General movements (GMs) assessments3 | Measurement at fidgety periods of life (between 10th weeks to 20th weeks) | General movements (GMs) are the spontaneous movement repertoire present from early foetal life until 20 weeks post-term. From birth to 8 post-term weeks, they have a writhing character and then till about 20 weeks a fidgety character. Two specific abnormal movement patterns reliably predict CP in fidgety term: F (-): the absence of the fidgety character from 8-20 post-term weeks. Fidgety movements (FMs) are classified as (a) normal (F+), (b) absent (AF), when normal FMs are never observed and (c) abnormal (F-). |
| The Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) | Change from the baseline of the BAYLEY-III score at 3, 6,12th month of infants | The BSID-III is a neurocognitive assessment used to evaluate infants from 0-42 months and to monitor their development with 5 domains: cognitive, language (receptive and expressive communication), motor (fine and gross motor), social-emotional, and adaptive functions (17). The first three domains will be assessed. To allow comparison of results from the 5 domains, a composite score will be calculated for each domain (mean, 100±15). A composite score below -2 standard deviation (SD) (\<70) will be considered a severe delay for all domains. |
