There is a need for appropriate classification to describe gross motor function status in a child with cerebral palsy (CP). It was hypothesised that: greater the number of limbs involved, higher would be the Gross Motor Function Classification System (GMFCS) level; and, there would be spectrum of GMFCS level for each of the topographical types of the cerebral palsy.

A cross-sectional study of 182 children of both sexes in the age group of 7 months to 30 years having spastic CP who attended CP clinic from 2008 to 2009 in tertiary care hospital were assessed for topographical diagnosis and GMFCS levels. Topographical distribution showed diplegia (42%), quadriplegia (30%), hemiplegia (23%), triplegia (4%) and monoplegia (1%). GMFCS levels were almost evenly distributed, level II (26%) was most common followed by level V (23%). Statistical analysis was done using Cramer's ratio and Pearson's Chi-square test.

Cramer's ratio of 0.277 showed fairly weak correlation between GMFCS levels and topographical CP types. Pearson's Chi-square (12) =41.7, p=0.000 indicates that there is significant difference between expected and observed values of number of limbs involved in GMFCS levels, further substantiating the weak correlation.

These results mean that GMFCS in different topographical groups have different distributions. It was also observed that GMFCS had weak correlation with the number of limbs involved, thus reflecting that the GMFCS is a better indicator of gross motor function impairment than the traditional topographical categorisation of CP that specifies the number of limbs involved.
