Abstract

PURPOSE
The purpose of this study was to identify the effects of reinforced walking exercise on dyspnea-fatigue symptoms, daily activities, walking ability and health related quality of life (HRQoL) in heart failure patients.
METHODS
This study used a randomized controlled trial design. The participants (experimental group=16, control group=25) were recruited from a university hospital in Kyeong-nam area. Data were collected from March to September, 2015. The reinforced walking exercise included goal setting and feedback (telephone and text message) provided for 12 weeks. Dyspnea-Fatigue Index, Korean Activity Scale/Index (KASI), six-minute walking distance (6MWD) and HRQoL were measured. Data were analyzed using descriptive statistics, t-test, Fisher's exact test, χ2 test, and Kolmogrove-Smirnov test.
RESULTS
Prior to the intervention there were no differences in the research variables between two groups. The exercise compliance in the experimental group was 100% (walking for 50 minutes per day, 5 times per week). The experimental group had improved dyspnea-fatigue symptoms (t=8.63, p<.001), daily activities (t=-4.92, p<.001), longer 6MWD (t=-5.66, p<.001), and increased HRQoL (t=-9.05, p<.001) compared to the control group.
CONCLUSION
The reinforced walking exercise could be a cost-effective intervention in heart failure patient, which could enhance patients' outcomes, such as improving dyspnea-fatigue symptoms, daily activities, walking ability, and quality of life.
