- Abstract
Background: Foot deformities, such as valgus and varus in the coronal plane and equinus in the sagittal plane, are common in children with cerebral palsy (CP). The purpose of this study was to describe the prevalence of coronal plane foot deformities and their association with the Gross Motor Function Classification System (GMFCS) level, age, CP subtype, and equinus in children with CP. Methods: A cross-sectional study was performed of 2784 children (1644 boys, 1140 girls), mean age 10 years, 2 months (standard deviation, 4.83), from the Swedish CP Follow-up Program and registry for 2021–2023. Single and multiple binary regression analyses estimated the association between coronal plane foot deformities (valgus or varus) and sex, age,... (More)
Background: Foot deformities, such as valgus and varus in the coronal plane and equinus in the sagittal plane, are common in children with cerebral palsy (CP). The purpose of this study was to describe the prevalence of coronal plane foot deformities and their association with the Gross Motor Function Classification System (GMFCS) level, age, CP subtype, and equinus in children with CP. Methods: A cross-sectional study was performed of 2784 children (1644 boys, 1140 girls), mean age 10 years, 2 months (standard deviation, 4.83), from the Swedish CP Follow-up Program and registry for 2021–2023. Single and multiple binary regression analyses estimated the association between coronal plane foot deformities (valgus or varus) and sex, age, GMFCS level, CP subtype, and equinus. Results: More than half (58%) the children with CP had valgus feet and 6% had varus feet. Valgus feet were more common in young children with high GMFCS levels, whereas the number of varus feet remained consistently low across all GMFCS levels. The prevalence of valgus feet was lower in older children at GMFCS I and II, but remained high in older children at GMFCS III–V. Coronal plane foot deformities were associated with higher GMFCS levels (odds ratio [OR] 11, 95% confidence interval [CI] 8–15 for GMFCS V), lower age (OR 1.5, 95% CI 1.3–1.7), and equinus (OR 1.9, 95% CI 1.4–2.5). Conclusions: Most children with CP have a coronal plane foot deformity. Valgus is most commonly associated with higher GMFCS levels and lower age. These findings contribute to a mapping of the children with an increased risk of foot deformities and also highlight the need for continuous follow-up of foot deformities in children with CP.
