Abstract Summary
This study is seminal in providing long-term functional outcome evaluations of single-event multilevel surgery (SEMLS) in children with cerebral palsy (CwCP, specifically bilaterally spastic CP). It presents a novel multidimensional representation demonstrating that all sagittal joint angles, on both sides, except ankle dorsiflexion, were significantly influenced [improvement and decline] by the SEMLS. It also showed that swing time variability (SWT CV), a surrogate measure of gait impairment, improves after SEMLS, while gait asymmetry (GA) and asymmetry ratio (AR) do not. All differences were durable over a 10-year period.
