The Relationship Between Pain, Muscle Strength and Lower Extremity Function in Patients with Knee Osteoarthritis

Abstract

Objective: Osteoarthritis OA is a problem causing functional disability and impairing quality of life. The presence of factors that may cause functional disability is important for OA patients. Therefore, we aimed to investigate the relationship between pain, muscle strength and lower extremity function in patients with osteoarthritis.Methods: A total of 58 patients 5 male, 53 female with a mean age of 60.63 ± 8.50 were included in the study. Pain level by Visual Pain Scale VAS , muscle strength by Jamar Hand Held Dynamometer, and lower extremity functional level by Lower Extremity Functional Scale were evaluated. Results: The mean VAS value at rest was 3.54±0.33, while the mean VAS value during the activity was 6.28±0.28. The lower extremity functional scale results were 36.01±1.87 points. When comparing the muscle strength of the knee with and without OA, while there is a difference between the extension muscle strengths, no difference was found between flexion muscle strengths p=.001, p=.580 . Knee OA knee muscle strength was positively correlated with non-OA knee muscle strength and lower extremity functional scale p
