A physiotherapy program tailored to the needs of infants from families who volunteer will be implemented until and including discharge. Parents of all infants discharged from the NICU will receive advice on holding, carrying, and positioning.

Infants from families who cannot attend physiotherapy for any reason (those living outside the province, those who cannot attend treatment sessions at the same frequency, working parents) will constitute the control group if they can come to the evaluations.

The early physiotherapy program will begin when the infant is stable and continue until discharge. Depending on the infant's gestational age and respiratory needs, chest physiotherapy, developmental physiotherapy, or both will be administered, if necessary. The early family collaborative physiotherapy program will begin from the first day the infant is stable and parental contact is established, and will consist of routine-based care and family education programs that include therapeutic holding, carrying, positioning, and sucking facilitation to stimulate postural responses. The physiotherapy group will receive a routine-based family collaborative early intervention program. This program will be based on a model of goal-oriented active motor learning and sensory strategy development in an enriched environment, and will include family education programs that integrate holding, carrying, and positioning training into daily routines. All parents will participate in the training.

Prechtl's General Movements (GMs) Assessment: General movements (GMs) are the spontaneous movement repertoire present from early fetal life until the 20th week postpartum. They are "writhing" until the 8th week postpartum and then "fidgety" until approximately the 20th week. Heinz Prechtl demonstrated the validity and reliability of this method by determining that infants without fidgety movements between 3 and 5 months of age are at high risk of developing CP. Video recordings will begin in the NICU 3 days after birth during the preterm period. All infants will be examined for writhing and fidgety movements (FM) using the video recordings. Movements during the preterm and writhing periods will be classified as PR, CS, and Ch GMs or normal. Movements during the fidgety period will be recorded as F+ or F++ when normal, AF when abnormal, or F- when not observed. Motor optimality scores will also be calculated for all infants during the fidgety period.

The HINE is a simple, standardized, and scoreable test for the clinical neurological assessment of infants aged 2-24 months. It consists of three sections: (1) a neurological examination that assesses cranial nerve function, posture, movements, tone, reflexes, and reactions; (2) motor milestones; and (3) behavior. Each of the 26 items on the test is first scored individually (0, 1, 2, 3, or half-point). A total score is then calculated, with a maximum score of 78. The total score is classified as optimal or suboptimal. Optimal scores are based on the frequency distribution of neurological findings in the population observed in at least 90% of infants in the age range studied. Higher scores indicate better neurological status.

The BSID-III is a neurocognitive assessment used to monitor the development of infants aged 0-42 months. It has five domains: cognitive, language, motor, social-emotional, and adaptive functions. This study will assess only the first three domains. Cognitive, language, and fine and gross motor skills will be assessed. A composite score is calculated for each domain (mean 100±15). A composite score below 2 standard deviations (SD) (<70) is considered a severe delay across all domains.

Prenatal/perinatal risks (MRI, cUS results, diagnosis, neurological evaluation) of all infants and their parents will be obtained from hospital records after treatment.
