title: Dynamic plantar pressure measurement for the normal subject: Free-mapping model for the analysis of pediatric foot deformities.
abstract: In measuring plantar pressures during gait, prior methods have divided the foot into five regions and neglected forefoot alignment as it is involved in intoeing and outtoeing. The authors' proposed free-mapping method divides the foot into nine regions and incorporates a pedobarograph foot progression angle. The purpose of the study was to provide normal pressure parameter data during stance phase using a free-mapping model. Sixty-six normal children, ages 6 to 16 years, were recruited and walked along the 5-m walkway at self-selected speeds. The mean and standard deviation for the plantar contact area, contact time, peak pressure, maximal mean pressure, pressure-time integral, force-time integral, instant of peak pressure, and instant of maximum force in nine foot regions are reported. These normative data will provide a basis with which assessment of foot deformities involved in clubfoot, pes planus, and cavus foot will be more accurately defined.
