title: Quantitative analysis of gait pattern and energy consumption in children with cerebral palsy.
abstract: The measurement of oxygen consumption during walking allows the quantification of gait expenditure, mainly in patients with musculoskeletal disabilities, as in cerebral palsy (CP). In this study, first, an experimental set up for the acquisition of energy consumption during gait analysis (GA) was proposed; secondly, some parameters of energy expenditure were analyzed to characterize pathological gait from an energetic point of view. Twenty CP children and 20 healthy children were evaluated during two consecutive sessions (session 1: only GA was performed; session 2: K4b2 was used during GA acquisition). The results revealed that the experimental set up was comfortable for all subjects. The absence of any differences in GA values between the two sessions showed that the use of a device for energy acquisition does not modify gait pattern. Energy expenditure index and oxygen cost presented abnormal values in comparison with normality and they were significant to quantify energy expenditure in CP children.
