“…The most widely researched clinical application is diabetic foot ulceration [1], a condition which can lead to amputation in extreme cases [2] but for which even mild-to-moderate cases are associated with substantial health care expenditure [3]. Pedobarography is also used in a variety of other clinical situations including: post-surgery biomechanical assessment [4], intra-operative assessment [5], orthotics design [6,7], and assessment of drop-foot surgery [8]. In addition to clinical applications, pedobarography continues to be used in the laboratory to understand the mechanisms governing human gait and posture [9,10].…”

The analysis of normal and pathological variation in human foot morphology is central to several biomedical disciplines, including orthopedics, orthotic design, sports sciences, and physical anthropology, and it is also important for efficient footwear design. A classic and frequently used approach to study foot morphology is analysis of the footprint shape and footprint depth. Footprints are relatively easy to produce and to measure, and they can be preserved naturally in different soils. In this study, we need to correlate footprint depth with corresponding foot pressure of individual using 3D scanner. Several approaches are used for modeling and estimating footprint depths and foot pressures. The deepest footprint point is calculated from z max coordinate-z min coordinate and the average of foot pressure is calculated from GRF divided to foot area contact and identical with the average of footprint depth. Evaluation of footprint depth was found from importing 3D scanner file (dxf) in AutoCAD, the z-coordinates than sorted from the highest to the lowest value using Microsoft Excel to make footprinting depth in difference color. This research is only qualitatif study because doesn't use foot pressure device as comparator, and resulting the maximum pressure on calceneus is 3.02 N/cm 2 , lateral arch is 3.66 N/cm 2 , and metatarsal and hallux is 3.68 N/cm 2 .
