Abstract: [Purpose] This study aims to explore the impacts of lower extremity exercise on the factor, the symptoms of knee osteoarthritis and the purpose of its treatments such as pain, stiffness, physical function, balance, and the quality of life. [Participants and Methods] Electronic bibliographic data of Medline and PubMed were examined to identify studies on Randomized Controlled Trials (RCT). 22,099 publications were identified and 21 studies met inclusion and exclusion criteria. The quality assessment, Cochrane’s risk of bias was used in all examined studies. [Results]21 studies were adequate for inclusion criteria. The meta-analysis based on the random effect model was employed to testify the effectiveness of lower extremity exercise on pain, stiffness, physical function, the quality of life, and balance of patients who suffer from knee osteoarthritis. Findings showed that lower extremity exercise contributed to reducing pain (effect size .20; 95% confidence interval .06 – .34) and improving physical function(effect size .14; 95% confidence interval .01- .27). In addition, lower extremity exercise helped to significantly improve stiffness, balance, and the quality of life. However, it was statistically insufficient due to severe deviations of studies (effect size .20; 95% confidence interval -.0.13 – .53).(effect size .11; 95% confidence interval -0.02 – .25). (effect size .16; 95% confidence interval -0.01 – .32). [Conclusion] Lower extremity exercise had affirmative effects on lowering pain which patients with knee osteoarthritis and improving stiffness, physical function, balance, and the quality of life all of which patients with knee osteoarthritis have in spite of the fact that stiffness, balance, and the quality of life were not statistically positive because of big deviations among studies.
