Abstract
Background Anatomy-based regionalization of pressure dynamic footprints has been proved to be feasible when accurate kinematic and baropodometric measurements are integrated [1]. The potential of this method is easily understandable when footprints are incomplete or severely altered; however, its thorough validation on healthy and pathologic feet is still required. This study focusses on anatomy-based masking in paediatric clubfoot using the Oxford Foot Model (OFM, [2]), which identifies 5 plantar regions of high clinical relevance in this population. Validation is based on the comparison with traditional geometrical masking using the same 5 regions, applied to young healthy volunteers and clubfeet.

Anatomy-based regionalization of pressure dynamic footprints has been proved to be feasible when accurate kinematic and baropodometric measurements are integrated [1]
Materials and methods 19 healthy volunteers (H: mean age 11.5 years, mean BMI 18.1) and 10 patients with clubfoot (P: mean age 10.8 years, mean BMI 19.9) were examined at the Oxford Gait Lab by using the OFM and an integrated experimental setup based on a VICON motion system and an EMED-m baropodometer. 3-5 footprints per foot were acquired for each individual while walking barefoot at self-selected speed
The automatic geometry-based regionalization (GM) which best fitted the OFM definition was used for comparison: it is based on the bisecting line of the foot and on the 23% and 55% perpendicular lines
