Relationship between gross motor function and magnetic resonance imaging findings in children with cerebral palsy

Abstract

This cross-sectional study was carried out at the department of Pediatric Neurology, Institute of Pediatric Neurodisorder and Autism, Bangabandhu Sheikh Mujib Medical University, Dhaka with the aim to assess the relationship between gross motor function and MRI findings in children with cerebral palsy. The duration of the study was 12 months. All the cerebral palsy cases who met the selection criteria were enrolled. Detailed history taking and physical examination was done. The gross motor function of all cases was evaluated according to Gross Motor Function Classification System- Expanded and Revised (GMECS-E and R). Magnetic resonance imaging of brain was done in all enrolled patients and reports were evaluated. MRI findings were classified as maldevelopment, cortical and subcortical gray matter lesion, periventricular white matter injury, basal ganglia lesion, normal and other findings. A total of 45 children with cerebral palsy aged between 2 to 12 years were included in this study. Mean age of the children was 4.73 (+3.17) years. Male were 31 and female were 14 in number. Functionally majority patients were in GMFCS level IV (26.7%) and level V (20%). MRI findings were abnormal in 35 (77.78%) cases. Most common abnormal MRI finding was cortical and subcortical grey matter lesions 22 (48.9%). This study revealed that cortical and subcortical gray matter lesions were significantly associated with higher level of GMFCS (IV-V) (P=0.038) and maldevelopment of brain were also significantly associated with higher level of GMFCS (P=0.01). Normal MRI findings had significant association with mild to moderate GMFCS level (I-III) (P=0.012). From this study significant relationship was found between gross motor function and MRI of brain findings in children with cerebral palsy.
