Correlation of Siting and Standing Performance with Gross Motor Functional Classification System in Children with Spastic Cerebral Palsy

Abstract

Background: Cerebral palsy (CP) is the most common motor disability in childhood, with spasticity as a frequent complication. Understanding the relationship between the Gross Motor Function Classification System (GMFCS) and motor abilities, such as sitting and standing performance, is critical for managing CP. Objective: This study aimed to analyze the correlation between sitting and standing performance with GMFCS in children with spastic cerebral palsy. Methods: A cross-sectional study was conducted with 350 children diagnosed with CP, aged 6-12 years. Data were gathered over six months at a government secondary school for special education. The GMFCS was used to classify motor function, while sitting and standing abilities were assessed using the Sit to Stand Test. Data analysis was performed using SPSS version 25, employing descriptive statistics and Spearman's rank correlation. Results: The study found that children at GMFCS levels I and II could often sit and walk with minimal or no assistance, whereas those at levels IV and V exhibited varied sitting abilities and primarily used technological aids or wheelchairs. A statistically significant association between sitting ability and GMFCS level was identified (Pearson Chi-Square = 29.151, p = 0.023). Children with spastic CP were predominantly classified at GMFCS levels III (49 participants) and V (49 participants), while those with dyskinetic CP were mainly at level II (13 participants). Conclusion: The GMFCS is an effective tool for assessing gross motor function in children with CP, with strong correlations found between GMFCS levels and sitting and standing performance. These findings can inform targeted interventions to improve mobility and quality of life for children with CP.
