A Survey of Foot Types in Normal Females between the Ages of 18 and 30 Years*.

*This Study was funded in part by a grant from the Chicagoland Orthopaedic Physical Therapy study Group. The purpose of this study was to determine the incidence of forefoot varus, forefoot valgus, subtalar varus, subtalar valgus, and tibiofibular varum in healthy females between the ages of 18 and 30 years. Fifty-eight females had both lower extremities evaluated to determine their foot type. Chi-square testing was used to determine significance between extremities for both the forefoot and rearfoot deformity groups. The relationship between left or right extremities for forefoot or rearfoot deformities was not significant. The forefoot valgus deformity was the most common forefoot imbalance in this sample. Rearfoot varus was present in 97 (83.6%) of the feet surveyed. Eighteen (31%) of the subjects had a different forefoot or rearfoot foot type bilaterally.J Orthop Sports Phys Ther 1988;9(12):406-109.
