Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Lokomat is a robotic treadmill gait trainer that is used to help people who have neurologic conditions walk better. Early research with children with cerebral palsy (CP) shows that it may help to improve walking skills. The purpose of this two-group randomized study is to compare Lokomat training to regular physiotherapy (PT) as far as impact on walking abilities and related function. The primary (alternate) hypothesis is that children will improve more with Lokomat training in terms of gross motor skills and walking endurance.

The investigators are enrolling 40 ambulatory children who are ages 5 to 12 years, have CP and are in Gross Motor Function Classification System (GMFCS) Level II (n=20) or III (n=20). In this crossover randomized clinical trial (RCT), whether PT or Lokomat intervention is done first is decided by an independent randomization process that occurs after the first baseline assessment. In the Lokomat phase, children receive 8 to 10 weeks of twice weekly therapy for a maximum of 16 sessions. Each session is 35 minutes plus the time needed for set-up. The 35 minute PT program is also given twice weekly for 8 to 10 weeks for a maximum of 16 sessions, and focuses on a menu-based strength, co-ordination, fitness, walking and balance activities. There is a 6 week break between the Lokomat and PT interventions.

Each child has four study assessments during their \~6 months in the study. The first assessment is done before starting the Lokomat or physiotherapy phase. The second happens after the first intervention has finished. The child then has a 6-week break period. The third assessment is done at the end of this break, and the fourth occurs after the second intervention. The PT assessor who does these assessments will not be the same as the PT who gives the intervention. The assessor is blinded to the child's intervention phase and previous assessment results. The primary outcome measures are the Gross Motor Function Measure and 6 minute walk test. Secondary measures evaluate gait, functional abilities, participation, health related quality of life and individualized goals.

The randomized aspect of the study lets us look at outcome differences between children for Lokomat and PT within their first intervention phase (n=20/group). The cross-over phase evaluates within-child outcomes across the two phases. A qualitative component is concurrently underway to examine child/parent experiences and their views of Lokomat outcomes.
