The Relationship between Physical Activity Levels and Functional Capacity in Patients with Advanced Chronic Kidney Disease

The purpose of this study is to assess whether the functional capacity of patients with chronic kidney disease stage V (CKD-5D) is different depending on their physical activity levels. We also compared functional capacity, quality of life, and symptoms of depression depending on treatment modalities (HD vs. PD). A Cross-sectional study included 52 patients (35HD and 17PD; males 61.5%, mean age 71 years). The main measurements were physical activity level using the Human Activity Profile questionnaire (HAP), muscle strength, functional capacity, health-related quality of life (HRQoL), and depressive symptomatology. The functional tests and physical activity levels correlated significantly. Participants on HD with low physical activity levels were older (*p ≤ .039) and had worst physical function (*p ≤ .01). The HAP is a useful tool to detect subjects with low functional capacity; there were no differences between the therapy modalities in terms of functional capacity, HRQoL, or depressive symptomatology.
