Background: Children with diagnosis of CP are at the risk of developing joint and muscle contractures. GMFCS was developed based on self initiated movement with particular emphasis on sitting and walking. SAROMM provides a method to determine the spinal deviations and range of motion limitations. There is greater emphasis on trunk and lower extremities than the upper extremities. Correlating these two scales will give us an idea of gross motor limitations and range of motion limitations in children with spastic cerebral palsy. Objectives: To find out the correlation between GMFCS and SAROMM in children with spastic cerebral palsy. Methodology: This study includes 60 spastic diplegic children between the ages of 5- 12 years. The children were screened for the inclusion and exclusion criteria. An informed consent was taken from the childs Parents and Guardians prior to the study. Results: The correlation between GMFCS and SAROMM was calculated using Pearsons Correlation Coefficient. There was positive correlation with r=0.538 and p=0.000. Interpretation & Conclusion: From this study we can conclude that there is positive correlation between GMFCS and SAROMM in children with spastic diplegia.
