Thesis Proposal Kristin Curcione Daemen College Abstract Daily physical activity can improve exercise tolerance and functional capacity in individuals with congestive heart failure (CHF). Previous measurement of functional capacity has been determined via a 6-minute walk test. This study examines the effect of a pedometer as a comparative tool to the 6-minute walk test for measurement of functional capacity as well as a motivational tool to increase physical activity in adults with chronic heart failure (HF). A randomized trial consisting of 40 participants will be implemented. Of the 40 participants, twenty will be randomized to a pedometer with step-based goal group, and the other twenty participants will be randomized to…show more content…
Introduction Over six million American’s have a diagnosis of heart failure with a projected 670,000 new cases per year (Braunwald, 2012). People over the age of 70 carry the greatest burden of chronic disease, disability, and health care use (Guralnik, Leveielle, Hirsch, Ferrucci, & Fried, 1997). Participation in physical activity is crucial for health, and walking accounts for much of the physical activity undertaken by sedentary individuals and those with chronic diseases (Buchner & Wagner, 1992). Pedometers can be a useful motivational tool to encourage increased walking as they are cheap and easy to use. Pedometers are simple and inexpensive body-worn motion sensors that are readily being used by researchers and practitioners to assess and motivate physical activity behaviors (Bravata et al, 2007). Valid assessment of physical activity is important to researcher and clinicians interested in surveillance, screening, evaluation, and intervention. Statement of the Research Problem/Purpose/Hypothesis/Questions The prevalence of heart failure continues to rise and can be classified as a clinical syndrome defined by characteristic symptoms and physical findings (Redfield et al, 2003). The aim of this study is to evaluate the effectiveness of the use of pedometers plus a theory-based step-goal intervention to assist patients with congestive heart failure to recognize activity ability and to accumulate increasing amounts of physical activity, mainly
