Comparing open kinetic chain with closed kinetic chain exercise on quadriceps strength and functional status of women with osteoarthritic knees

Abstract

Aim. The objective of this study is to show the effectiveness of close kinetic chain exercise (CKC) over open kinetic chain exercise (OKC), on female osteoarthritic knee.
Method. Thirty female osteoarthritic patients were selected on the basis of their inclusion and exclusion criteria and they were randomly divided into two groups of 15 patients in each group. Group A was provided with CKC while group B was given OKC exercises. The readings were taken on day 0 and day 35 during the 5 weeks study.
Result. The result of the effectiveness of CKC over OKC is obtained through WOMAC scale and Strain gauge. Through these two scales the strength and functional activity of the quadriceps muscle is evaluated.
Conclusion. The study shows that closed kinetic chain exercises are more effective than open kinetic chain exercises on female osteoarthritic knees.
