In this period, cerebral palsy research coalesced around a multifactorial etiology linking obstetric factors, birth weight, gestational age, and postnatal events to CP, with acquired CP from post-neonatal infections and trauma. Clinical development emphasized motor impairment with cognitive and behavioral dimensions, tracking the maturation of postural reflexes and habitual movement patterns across childhood. Rehabilitation and orthopedic management focused on normalizing postural control, foot/hip alignment, and early surgical decision-making, while neurovisual and perceptual-cognitive studies highlighted visuomotor deficits and the need for integrated assessment in pediatric CP cohorts. Congenital and familial patterns emerged from twin studies, underscoring etiological heterogeneity and developmental trajectories across CP variants.\nInfluential Works: Cross-period contributions established standardized terminology and classification of cerebral palsy, enabling consistent diagnostic reporting and cross-study comparability. The Very Early Treatment of Cerebral Palsy argued for initiating therapy in infancy to maximize motor outcomes and shape infant-care programs. Foundational orthopedic and etiological studies, including foot alignment research and explorations of minimal cerebral dysfunction and metabolic linkage to cerebral palsy phenotypes, broadened CP concepts and guided future research.
