Multiple studies have documented that children with cerebral palsy display significant deficits in function, muscle strength and muscle activation. Anecdotal reports of children with cerebral palsy involved in ince-skating suggest gains in function, endurance, and mobility. The purpose of this study was to examine the differences seen in the lower extremity surface electromyographic (SEMG) activation and the Energy Expediture Index (EEI) during ice-skating compared to overground ambulation on level surfaces in children with cerebral palsy.
