The purpose of this study was to investigate the effects of Korea traditional dance-based step exercise using device on balance confidence and quality of life in the elderly. The subjects were 52 elderly women, who random assigned in one of Korea traditional dance-based stepping(18), walking(8), and control group(26). The participants of intervention programs did exercise 40-minute per day, twice per a week, during 12 weeks. They responded to Activities-specific Balance Confidence(ABC) and health-related quality of life scale(SF-8) after completing exercise intervention. Collected data were analyzed using One-way ANOVA and Pearson correlations through SPSS 17.0 version. The results were as follows. First, the group of Korea traditional dance-based stepping(M=89.55) had higher in the score of balance confidence than walking(M=72.81) and control group(M=53.05)(F=22.62, p<.05). Second, exercise intervention groups of Korea traditional dance-based stepping(M=16.00) and walking(M=19.50) had lower in the score of quality of life than control group(M=25.19)(F=15.74, p<.05). However, there was no significant difference in quality of life between intervention groups. Finally, there was significant correlations between balance confidence and quality of life in total case(r=.692, p<.05) and walking group(r=-.823, p<.05). These results means that Korea traditional dance-based step exercise using device is more effective intervention than walking in terms of balance confidence in elderly.
