Abstract

Osteoarthritis is the most common type of arthritis and is considered one of the 10 main causes of disability in the world. The main aim of this study was to compare the effects of a quadriceps strengthening exercise course with a combined exercise course (resistance, stretching, open and closed chain) on pain, balance, quality of life, and the strength ratio of quadriceps to hamstring in women 50-60 years old with knee osteoarthritis.

In this semi-experimental research, 45 women with osteoarthritis, were selected as available with full knowledge of the work implementation steps and randomly divided into three groups of quadriceps strengthening exercises, Combined and control exercises. Before starting the exercises the VAS pain questionnaire,, the global and localized WHOQOL-BREF questionnaire,, the Sharpend-Romberg test, and the standing and walking time test were used, , for the pre-test. A dynamometer was also used to collect the required information on the ratio. Exercise protocols were completed for 4 weeks, 5 sessions per week. All the tests were repeated at the post-test. Descriptive statistics and ANOVA statistical methods were used to investigate the research variables.

Pain index, static and dynamic balance, and quadriceps-to-hamstring strength ratio significantly decreased both quadriceps strengthening and combined training groups. No significant changes were observed in the control group.

So, both exercise protocols have improved all factors in 50 to 60-year-old women with knee osteoarthritis, and using these two exercise protocols is recommended for that
