MRI and 3DGA data including marker trajectories and ground reaction forces of twelve children diagnosed with CP (10.4 ± 3.8 years old, height: 133.6 ± 16.1 cm, mass: 30.1 ± 10.8 kg) and thirteen TD children (10 ± 2.2 years old, height: 144.5 ± 8.5 cm, mass: 36.8 ± 9.5 kg) were analyzed for this study. All participants walked without walking aids and with a self-selected speed. The data of all CP children and three TD children was captured during a previous study (Kainz et al., 2017 (link)) while the data of the remaining ten TD children was additionally collected for the purpose of this study. Ethics approval was obtained from the local ethics committees (University of Vienna, reference number 00578). Data collection of the retrospective analyzed data (CP children and three TD children) is described in detail in Kainz et al. (2017) (link).
MRI images of the additionally recorded data (ten TD children) were collected using a 3T magnetic resonance scanner (MAGNETOM Vida, Siemens, Berlin/Munich, Germany) with a T1 vibe sequence with a voxel size of 0.8 × 0.8 × 0.7 mm. 3DGA-data for these ten TD children were captured on the same day as the MRI images using a 12 camera motion capture system (Vicon Motion Systems, Oxford, UK). The used marker set during the motion capturing was based on the Plug-in-Gait marker set (Kadaba et al., 1990 (link); Davis et al., 1991 (link)) with additional clusters of three markers on each thigh and shank segment and an additional marker at the 5th metatarsal head of each foot. Simultaneously, ground reaction forces were acquired using five force plates (Kistler Instrumente, Winterthur, Switzerland). All children performed several gait trials with a self-selected walking speed. Marker trajectories were captured, labelled, and filtered (Butterworth 4th order, 6 Hz low-pass filter) in Nexus 2.12.1 (Vicon Motion System, Oxford, United Kingdom).
