Abstract

Introduction: The purpose of this study was to determine whether tract-specific diffusion tensor imaging measures in somatosensory and motor pathways correlate with clinical grades as defined using the Gross Motor Function Classification System (GMFCS) in cerebral palsy (CP) children. Methods: Quantitative diffusion tensor tractography was performed on 39 patients with spastic quadriparesis (mean age=8 years) and 14 age/sex-matched controls. All patients were graded on the basis of GMFCS scale into grade II (n=12), grade IV (n=22), and grade V (n=5) CP and quantitative analysis reconstruction of somatosensory and motor tracts performed. Results: Significant inverse correlation between clinical grade and fractional anisotropy (FA) was observed in both right and left motor and sensory tracts. A significant direct correlation of mean diffusivity values from both motor and sensory tracts was also observed with clinical grades. Successive decrease in FA values was observed in all tracts except for left motor tracts moving from age/sex-matched controls to grade V through grades II and IV. Conclusion: We conclude that white matter tracts from both the somatosensory and the motor cortex play an important role in the pathophysiology of motor disability in patients with CP.
