Toma de molde en carga con control de presiones en pies pronados

Abstract

Introduction

Foot casting is essential in orthotic treatments. Several materials and procedures are involved in this process. There is no evidence of the reliability of casting techniques, as these procedures are based on the subjectivity of the podiatrist more than objective references. The aim of this study was to demonstrate the efficacy of a foot casting technique using plantar pressure sensors.

Material and method

The study was conducted on 9 people with 15 pronated feet (FPI > 6). A total of 3 types of foot weight-bearing casting were taken (relaxed position, controlled position, and controlled position using load sensors). The Heel Symmetry Index and 1st-5th metatarsal head height difference was calculated and compared in the 3 types.

Results

The comparison of Heel Symmetry Index in the different groups showed significant differences (P = .001). The 1st-5th metatarsal head height difference variable showed values of P < .001 in the different groups.

Conclusion

Foot casting by controlled plantar sensors achieved a more balanced cast with greater heel symmetry, and less difference in the 1st-5th metatarsal head heights.
