Objective Children with cerebral palsy (CP) experience functional limitations because of excessive muscle weakness, spasticity, and impaired motor control. They are prescribed ankle foot orthoses (AFOs) to assist with ambulation. Our objective was to analyze stride length and dorsiflexion data comparing the effectiveness of “AFOs” with “barefoot or shoes only” on ambulatory children with CP.

Design An electronic literature search was conducted. Studies were screened by two reviewers based on our inclusion criteria: prospective cohort study or randomized clinical trial (RCT), participants <18 years of age with a primary diagnosis of CP, AFOs with a control group, 20 combined participants in the experimental and control groups for cohort studies, and 10 participants for RCT’s.

Results Seventeen studies were selected. Pooled results of the meta-analyses showed that stride length was significantly better in the AFO group as compared with the control group (Mean difference between groups = 0.05m (95% CI = (0.04, 0.06)). The dorsiflexion angle (5 studies; 124 participants) was improved in patients with AFOs as compared with barefoot or shoes only (Mean difference between groups = 8.62o (95% CI = 8.05, 9.2)).

Conclusion Children with CP using AFOs had improved stride length and dorsiflexion angle during gait in a pooled meta-analyses of cohort studies and clinical trials.
