Abstract
Toe deformities are highly prevalent in older people with up to 74% of older men and women having some degree of hallux valgus [1]. Despite the well documented hypotheses that atrophied, or weak toe flexor muscles are associated with the formation of toe deformities [2], there has been little evidence to support this theory. Only one study has directly compared the toe flexor strength of individuals with toe deformities to those without, revealing that older people with hallux valgus have reduced hallux strength compared to those without the deformity [3]. Therefore, to further investigate the pathomechanics of hallux valgus, this study aimed to determine whether the size of the abductor hallucis muscle differed in older women with and without hallux valgus deformity.
Highlights
Forty-four older adults (60+ years) were recruited to participate in the study. Each participant had their feet assessed by the Chief Investigator (KJM), with hallux valgus severity rated using the Manchester Scale [4]
Muscle cross-sectional area (CSA) was measured using Image J software with the assessor blinded to group allocation
Toe deformities are highly prevalent in older people with up to 74% of older men and women having some degree of hallux valgus [1]
Summary
Toe deformities are highly prevalent in older people with up to 74% of older men and women having some degree of hallux valgus [1]. Forty-four older adults (60+ years) were recruited to participate in the study.
