Referral source was defined as the professional that referred the child to physiotherapy. Complicated birth history was defined as the number of known risk factors for CP, such as stroke, infections, or seizures (Appendix 1), detectable before 5 months of age. Motor severity was described using the Gross Motor Function Classification System (GMFCS) at two years.18 Distinctions between levels are based on functional abilities, where Level I indicates the highest and Level V the lowest functional level. Children at GMFCS Level I-III are ambulatory with or without assistant, while those at GMFCS Level IV-V are considered non-ambulatory and dependent on wheeled mobility. Type of CP was described by motor type and topography.
