Abstract
Weakness of the hip extensor muscles contributes to the walking impairment of children with cerebral palsy, but it is difficult to strengthen these muscles. This study demonstrates greater activation of the hip extensor muscles when using a tricycle developed for this purpose than when using a traditional tricycle. The hip-extensor tricycle was also found to be more stable than a traditional tricycle. A 10-week field trial of the hip-extensor tricycle showed that visually analysed gait improved, but hip extensor strength did not. However, children used and enjoyed the tricycle, and parental reports were positive. This tricycle could be used to supplement other means of improving gait in children with CP.
