| Abstract: | [Purpose] To clarify the relationship between lower extremity function and activities of daily living and characterize lower extremity function in hospitalized middle-aged and older adults with subacute cardiovascular disease. [Participants and Methods] The Short Physical Performance Battery, 6-minute walk distance, and functional independence measure tests were conducted in 79 inpatients with subacute cardiovascular disease (mean age, 76.7 ± 11.9 years; 34 females). Multiple regression analysis used the functional independence measure score as the dependent variable and the Short Physical Performance Battery and 6-minute walk distance scores as independent variables. Cross-tabulations were performed for each age group, and patients who performed the Short Physical Performance Battery and 6-minute walk distance tests were divided into two groups by their respective cutoff values. [Results] Only the Short Physical Performance Battery (β=0.568) and 6-minute walk distance (β=0.479) scores were adopted as significant independent variables in each multiple regression model. The age <75 years group had the most patients with both good lower extremity function and aerobic capacity, whereas the age ≥75 years group had the most patients with both functions impaired. [Conclusion] Although cardiovascular disease is generally associated with decreased aerobic capacity, many older patients with cardiovascular disease in this study had decreased lower extremity function, too. |
