Introduction: The aim of the study is to determine the effect of a course of resistance and quadriceps strengthening exercises on pain, walking speed, quality of life and balance in elderly women with knee osteoarthritis.
Research Method: The research method was semi-experimental and pre-test, post-test. The statistical population included 45 women with an average age of 65 years in Borujerd city, who were randomly divided into three groups (group one: resistance exercises, group two: quadriceps strengthening exercises, and group three: control). Pain variables were assessed with (VAS), walking speed with the rise time and treadmill test, quality of life with WHOQOL-BREF questionnaire, static and dynamic balance tests with the Sharpand and Romberg tests. The subjects in the intervention group performed the exercise 5 sessions per week for 4 weeks. The control group did not receive any intervention during this period. Data analysis was performed with SPSS software (version 26) and two-way ANOVA test, and for the difference between the pre-test and post-test groups, the paired t-test was performed at a significance level of p <0.05.
Results: The results of the paired t-test showed that both resistance and quadriceps strengthening exercise groups significantly improved pain intensity and quality of life compared to the control group after the intervention (p <0.001). However, there was no significant improvement in walking speed, static and dynamic balance compared to the control group (p <0.05).
Conclusion: According to the effectiveness of research findings, both exercise protocols are suggested to improve these factors in elderly women with knee osteoarthritis.
