The objective of this study is to develop a new device (foot piece) to attach to the
inner surface of the shoe insole (anterior region of the first-ray of the foot) promoting
a small elevation and, consequently, the hypothesis of correction in alignment of this
region and relief of symptoms caused by alterations resulting from Hallux Valgus. To
verify the functional changes and possible signs and symptoms of the pathology, the
Brazilian version of the Foot Function Index was applied in the initial and final phases
of the study. To assess the alignment of the hallux, computerized biophotogrammetry
was performed with specific software to record and compare the evolution after a defined period of the use of the new piece. The main objectives of this paper are to show
the preliminary results obtained, which suggest that there may be an improvement in
both pain symptoms and correction of hallux deviation.
