Analysed Dataset - Prediction of ground reaction forces and moments during walking in children with cerebral palsy

The full-body marker set of the conventional gait model (CGM 2.2, 9.5mm diameter markers, VICON, Oxford Metrics Ltd, UK) was used to collect the kinematic data. Four force plates (sampling frequency 1500Hz, Kistler Instrumente AG, Winterthur, Switzerland) embedded in the laboratory floor were used to collect kinetic information.

Each participant was asked to walk barefoot over the 12m instrumented walkway until six valid stride cycles for each leg were captured, i.e. when only one foot contacted each force platform, without stepping over its edges. Trials with excessive soft tissue artefact, poor consistency, or signs of inaccurate marker placement were excluded. Markers data were labelled, gap-filled, and filtered (Woltring filter, mean squared error set to 10mm2) using Vicon Nexus (version 2.8.2, Vicon, Oxford Metrics Ltd, UK).
