applicable to this cohort, they add to the limited existing knowledge in this area and may assist decisions regarding surgical timing, number of procedures, and intensity of rehabilitation postoperatively.The excellent study by Dequeker et al. highlights the need for a comprehensive biomechanical evaluation using three-dimensional gait analysis, including all domains of the ICF before SEMLS. This assessment is essential for the evaluation of outcomes post SEMLS, as well as to inform surgical decision-making, planning of rehabilitation, and resource allocation on an individual basis for each child. 2.
