Management of children with ambulatory cerebral palsy: an evidence-based review. Commentary by Hugh Williamson Gait Laboratory staff.

Overview

The evaluation of complex interventions, such as Single Event Multilevel Surgery (SEMLS) requires more than randomized controlled trials. Rehabilitation following SEMLS is prolonged and the outcomes of interest may not be apparent for 5 years or more after the surgery. We suggest long term, prospective cohort studies with objective outcome measures be recognized as of equal importance to randomized controlled trials. The evidence in support of instrumented gait analysis (IGA) is also reviewed. We suggest that clinical levels of evidence are not an appropriate method to evaluate a measurement tool. Specifically, IGA should be evaluated in terms of validity, reliability and cost effectiveness. We demonstrate that the use of IGA has improved medium and long term outcomes in ambulant children with cerebral palsy in a center where IGA has been used routinely both for planning SEMLS and for monitoring outcomes.
