Low levels of physical activity (PA) are ubiquitous among patients with end-stage renal disease. The purpose of the study was to examine the role of brief inpatient intradialytic exercise (IDE) in improving antecedents of PA participation.
A patient with chronic kidney disease completed 1 exercise session using a leg ergometer, while undergoing dialysis. Under the supervision of a physical therapist, the patient performed an exercise protocol that included 3 phases: (1) 15 minutes of continuous intradialytic aerobic activity, (2) followed by a 15-minute passive rest break, and (3) a second 15-minute continuous bout of intradialytic aerobic activity using a leg ergometer. Pedaling speed was based on the patient comfort level while attempting to reach an exercise intensity of 13 on the Borg scale. Self-report pretest and posttest surveys, including fear avoidance, exercise self-efficacy, chronic disease self-efficacy, attitude, and intention to exercise, were completed.
The largest positive change in scores was intention to exercise in the next 3 months (Δ = 250%; raw change 5 points), the number of days she intended to exercise next week (Δ = 250%; raw change 5 points), followed by intention to exercise next month (Δ = 75%; 3 points), fear avoidance (Δ = 40%; 6 points), intention to exercise next week (Δ = 20%; 1 point), chronic disease self-efficacy (Δ = 20%; 0.7 of a point), general exercise self-efficacy (Δ = 5.7%; 0.2 of a point), and attitude toward exercise (Δ = 5.6%; 0.7 of a point).
Participation in 1 IDE session by a patient with chronic kidney disease led to improvement in determinants of self-efficacy and intention to engage in PA. This case study supports further examination of a brief inpatient intervention with an IDE bout to increase PA.
