To use HRT in the assessment of individuals with peripheral arterial occlusive disease (PAOD), its ability to detect differences in the functional performance of patients with PAOD must be verified.Aim: To verify whether the test is sensitive in differentiating between individuals with PAOD with distinct functional capacities.Materials and methods: A transversal study in which individuals with PAOD were assessed using the HRT, the Walking Impairment Questionnaire (WIQ), and the Shuttle Walk Test. The following variables were analyzed: number of plantar flexions performed in the HRT (time in seconds) and velocity (plantar flexions per second) when performing plantar flexions up to the point of volunteer fatigue, maximum distance walked in the Shuttle Walk Test, and scores obtained in each WIQ domain.Results: Twenty-five individuals (14 male) were included in the study, with a mean age of 63.36 ± 9.83 years. The variables number of plantar flexions and time to perform the HRT were sensitive enough to differentiate between distinct functional capacities in individuals with PAOD (P = 0.003 and P = 0.009, respectively). However, this result was not found for the variable of velocity in the HRT. The number of plantar flexions in the HRT was sensitive enough to differentiate individuals of extreme classes on the WIQ domain, stairs (P = 0.008).Conclusion: The HRT can be applied in clinical practice as a valid assessment of the distinct function capacities of individuals with PAOD.Keywords: peripheral arterial disease, heel-rise test, walking impairment questionnaire, functional capacity, shuttle walk test
