Purpose: The purpose of this study was to examine the effect of a progressive lower-extremity exercise program on pain, efficacy of exercise, and the life satisfaction among older women with TKRA. Methods: This study was a nonequivalent control group non synchronized design and was conducted from 12 September 2012 to 05 February 2014 in G-university hospital located in J-city. The sample was composed of an experimental group (n=20) and a control group (n=20). The progressive lower extremity exercise program was applied to the experimental group for 13 days. NRS scale was used to measure the pain, self-efficacy of exercise was measured by Exercise Self Efficacy, and life satisfaction was measured by 8 item questionnaire. Results: The experimental group was significantly lower in the degree of pain (F=73.53, p<.001), higher in the degree of self-efficacy of exercise (F=61.42, p<.001) and life satisfaction (F=80.91, p<.001) than the control group. Conclusion: The progressive lower-extremity exercise program for TKRA patients was useful to reduce pain and improve self-efficacy of exercise and life satisfaction, To reduce the pain and th improve the life satisfaction of older women with TKRA, we need to provide the progressive exercise at bedside during the postoperative recovery phase.
