Quadriceps muscle strength in patients with knee osteoarthritis

Abstract

  Osteoarthritis is degenerative disease mainly affects weight bearing joints. Usually patients with knee osteoarthritis have pain, stiffness and functional limitation. This functional limitation might be caused by muscle weakness specially in quadriceps muscle. The hand held dynamometer is widely used in the clinical setting as a valid and reliable outcome measure, which used in this study to measure quadriceps muscle strength during supported and unsupported sitting. It can be concluded that subjects produce greater force in supported sitting than in unsupported sitting.
