Correlation between physical functioning and gait measures in children with cerebral palsy.

The primary aim of this investigation was to assess the correlation between the POSNA Musculoskeletal Functional Health Questionnaire (POSNA) and gait analysis in children with cerebral palsy (CP). POSNA and computerized gait analysis were used to evaluate individuals with CP. Correlations were investigated between POSNA scales, gait parameters, and the Gillette Functional Assessment Questionnaire (FAQ) in 63 children (31 males, 32 females; mean age 9.17 years [SD 3.06], age range 3.75 to 16.44 years) with spastic CP. Twelve participants had hemiplegia, 29 diplegia, 12 quadriplegia, and 10 triplegia. The result of backwards stepwise multiple regression analysis indicated that the Log normalcy index (NI) was a significant predictor of the POSNA Global Function and Comfort scale. Energy expenditure (EE) did not add significantly to the prediction. The POSNA scales differentiated between the different topographical types of CP. The POSNA scale is a valid and useful clinical measure. Used in conjunction with the NI, EE, and FAQ, the POSNA scale provides a more complete appraisal of change in functioning.
