BACKGROUND: To our knowledge, hand dominance and side of foot disorders has not been described in the literature. We sought to evaluate whether hand dominance was associated with ipsilateral foot disorders in community-dwelling older men and women.
METHODS: Data were from the Framingham Foot Study (N = 2,089, examined 2002-2008). Hand preference for writing was used to classify hand dominance. Foot disorders and side of disorders were based on validated foot examination findings. Generalized linear models with generalized estimating equations were used to estimate odds ratios and 95% confidence intervals, accounting for intraperson variability.
RESULTS: Left-handed people were less likely to have foot pain or any foot disorders ipsilateral but were more likely to have hallux valgus ipsilateral to the left hand. Among right-handed people, the following statistically significant increased odds of having an ipsilateral versus contralateral foot disorder were seen: 30% for Morton's neuroma, 18% for hammer toes, 21% for lesser toe deformity, and a twofold increased odds of any foot disorder; there was a 17% decreased odds for Tailor's bunion and an 11% decreased odds for pes cavus.
CONCLUSIONS: For the 2,089 study participants, certain forefoot disorders were shown to be ipsilateral and others were contralateral to the dominant hand. Future studies should examine whether the same biological mechanism that explains ipsilateral hand and foot preference may explain ipsilateral hand dominance and forefoot disorders.
