Physical activity level is associated with the O2 cost of walking in cerebral palsy.

Purpose: To determine, in children and adolescents with cerebral palsy (CP), the relationship between physical activity level (PAL) and i) oxygen cost of walking, and ii) peak VO2.

Methods: In 11 subjects (10.6-16.

Habitual physical activity levels are associated with biomechanical walking economy in children with cerebral palsy.

Objective: To evaluate in children and adolescents with cerebral palsy the relationship between habitual physical activity and biomechanical treadmill walking economy and whether treadmill belt speed or walking time affect economy.

Design: Physical activity was measured in 11 subjects (10.6-16.
