AimTo identify the most frequently reported non‐instrumented measures of gait, activity, and participation in children with cerebral palsy (CP) after undergoing gait corrective orthopaedic surgery.MethodFour databases were searched from database inception to the 9th December 2021 for studies that evaluated functional outcomes for children with CP under 18 years undergoing gait corrective orthopaedic surgery.ResultsOf 547 citations, 44 publications (n = 3535 participants, n = 1789 males, mean age 10 years 5 months [SD = 3 years 3 months], Gross Motor Function Classification System levels I–III at the time of surgery) were eligible for inclusion. Fourteen different outcome measures were used: one measure of gait, 10 measures of activity, and three measures of participation. Gait was measured with the Edinburgh Visual Gait Scale (EVGS; 4 out of 44). The most common activity and participation measures were the Functional Mobility Scale (FMS; 15 out of 44) and Pediatric Outcomes Data Collection Instrument (11 out of 44) respectively. No studies reported a combination of gait, activity, and participation measures.InterpretationThe EVGS and FMS should be considered as core outcome measures in gait corrective orthopaedic surgery, while a measure of participation is unclear. Additional considerations for developing a comprehensive suite of outcomes include identifying a combination of clinical measures and performance‐reflective questionnaires that are standardized for children with CP undergoing surgery and meaningful to clinicians and families.
