The aim of the study is to compare factors associated with physical performance in older individuals with severe knee osteoarthritis and those with less-severe osteoarthritis. This is an ancillary cross-sectional study to a population-based cohort study focusing on Koreans age 65 years or older. The analysis included 553 subjects with information about knee pain, depressive symptoms, and comorbidities collected by self-reported questionnaire, and body weight, knee osteoarthritis severity, muscle strength, and physical measures by observer-rated tests. Stepwise logistic regression analyses were performed with physical performance as an outcome variable and the others as independent variables across radiographic knee osteoarthritis severity. In the minimal-to-moderate-severity group, muscle strength, knee pain, BMI, and age were related to poor performance (OR [CI] 0.81 [0.73-0.90], 1.12 [1.03-1.21], 0.87 [0.79-0.96], and 1.09 [1.05-1.14], respectively). In the severe group, muscle strength was the only factor significantly associated with poor performance (OR [CI] 0.72 [0.58-0.89]). Muscle strength, knee pain, and BMI were important determinants of physical performance in the older population with knee osteoarthritis. In severe knee osteoarthritis patients, muscle strength was the only significant determinant.

BACKGROUND: Although sports participation is allowed to most adult patients with corrected tetralogy of Fallot, a reduced exercise tolerance and reduced perceived physical functioning is often present in these patients. We aimed to investigate daily physical activity in adults with tetralogy of Fallot and to investigate the underlying determinants of physical activity in daily life. METHODS: We studied 73 patients with tetralogy of Fallot (53 male; mean age 27.3 ± 7.9 years) who underwent echocardiography and cardiopulmonary exercise testing, and who completed questionnaires about physical activity and perceived health status. All variables were compared with data from a general population. Relationships were studied by Pearson or Spearman correlation coefficients with correction for multiple testing. RESULTS: Patients were significantly less active compared with the general population (p > 0.05), 55% of all patients were sedentary, 27% had an active or moderately active lifestyle, and 18% of the group had a vigorously active lifestyle. Peak oxygen uptake (71 ± 16%; p < 0.0001) was significantly reduced and related to reduced physical activity levels (r = 0.229; p = 0.017) and perceived physical functioning (r = 0.361; p = 0.002). CONCLUSIONS: Adult patients with tetralogy of Fallot have a sedentary lifestyle and are less active than the general population. Inactivity significantly contributes to reduced exercise capacity, in addition to the impairment based on the cardiac condition. Moreover, reduced exercise capacity and the intensity of sports performed in daily life are related to perceived physical functioning. Individual patient counselling on physical activity might be a low-cost, high-benefit measure to be taken in this patient population. HubMed – rehab
