This study used a quasi-experimental research design with pretest-posttest control groups and aimed to examine the effects of a physical activity promoting program on self-efficacy for physical activity, the severity of knee osteoarthritis, and balance among persons with knee osteoarthritis.The program was developed based on the self-efficacy theory. The study recruited 78 persons with knee osteoarthritis who sought care service at an outpatient clinic. The sample was randomly assigned either to the experimental (n = 39) or control group (n = 39). Those in the experimental group received the physical activity promoting program, while those in the control group received routine care. The instruments used in this study included the Demographic Questionnaire, the Self-Efficacy Scale for Physical Activity, the Severity of Knee Osteoarthritis Questionnaire and the Timed Up and Go Test. Data were analyzed using descriptive statistics, independent sample t-test, and repeated measures ANOVA. The results showed that the experimental group had a significantly higher mean score of self-efficacy for physical activity and a significantly lower mean score of the severity of knee osteoarthritis at weeks 4 and 8 after receiving the program than did the control group. Although the physical activity program could not change the balance significantly, the experimental group improved its mean score for balance over time. The findings suggested that the program should be applied to enhance the perceived self-efficacy for physical activity, balance, and reduced the severity of knee
osteoarthritis in persons with knee osteoarthritis. The healthcare team should use this program continuously for decreasing the severity of knee osteoarthritis and increasing balance to prevent falls among persons with knee osteoarthritis.
