- Description
- Background: A weight bearing ankle equinus has adverse effects on forefoot plantar pressure variables in older adults with diabetes, but it is unclear if this is also the case in older adults without diabetes. Methods: 40 older adults with diabetes (88% type 2, mean diabetes duration 17.6 ± 14.8 years) and 40 older adults without diabetes, matched for age (±3 years), sex and BMI (±2 BMI units) were included (63% female, mean age 72 ± 4 years, BMI 30 ± 4 kg/m2). Primary outcomes were prevalence of a weight bearing equinus and evaluation of barefoot forefoot plantar pressures in older adults with and without diabetes. Findings: A weight bearing equinus was present in 37.5% and 27.5% of the diabetes and non-diabetes group respectively with no significant difference between groups (p = 0.470). People with diabetes and equinus displayed higher peak pressure (808 versus 540 kPa, p = 0.065) and significantly higher pressure-time integral (86 versus 68 kPa/s, p = 0.030) than people with diabetes and no equinus group. The non-diabetes equinus group had significantly higher peak pressure (665 versus 567 kPa, p = 0.035) than those with no diabetes and no equinus, but no difference in pressure-time integral. Interpretation: A high prevalence of a weight bearing equinus was detected in older adults with and without diabetes, with associated increases in plantar pressures. As an equinus has been associated with many foot pathologies this study's findings suggest that clinicians should check for the presence of a weight bearing ankle equinus in all older adults.
