Evaluation of factors affecting hallux valgus in elderly females

Abstract

[Purpose] The purpose of this study was to evaluate factors affecting hallux valgus in elderly females, with attention paid to the foot shape. [SubjectsandMethods] The subjects consisted of 176 females (mean age, 73.8±5.7 years) in the community who belonged to a health club for the elderly and underwent a physical fitness test. To identify factors affecting hallux valgus, the following items were evaluated: age,height,body weight, Body Mass Index, and foot/toe morphological variables (foot length, foot width,first-toe angle, fifth-toe angle, spread foot angle, and the ground contact states of the sole and toes) measured using a foot pressure distribution measurement system. In addition,the presence or absence of hallux valgus and floating toes was determined. [Results] As a result of stepwise multiple regression analysis, only the foot width was identified as a factor affecting hallux valgus. [Conclusion] For the health of the foot and toes, the size of shoes should be selected with consideration given to not only the length but also width of the foot.
