Effect of Open Kinetic Chain on Functional Activities of Patients with Knee Osteoarthritis

Abstract

In doing daily activities, limbs of the lower extremities are the most important parts of the body. The knee is the main joint to support the body that the joint cartilage becomes inflamed which can cause pain so it can interfere to its functional activities. Nowadays, our society cannot be separated from all physical activities that involve personal or group activities. Walking, squatting, going up and down stairs, and even running are the most physical activities done by the society. Osteoarthritis is a process of degeneration and repairmen of connective tissue, cartilage, synovium, and subchondral bone. Interventions can be given in the form of exercises improving the ability of functional activities, namely open kinetic chain which this exercise can accelerate blood circulation, prevent contractures, increase muscle strength or muscle strength, relax muscles and knee joints. The aim of this study was to determine the effect of open kinetic chain exercise and increased functional activity on knee osteoarthritis. This study used a quasi-experimental and one group pre and post-test design. The sample of this study was 12 people who had been characterized by the inclusion and exclusion criteria. Measurement of the functional activity value was carried out by women and the results of the study were analyzed using the repeated ANOVA measurable test. The data analysis test showed that the open kinetic chain can increase functional activity on knee osteoarthritis from time to time with an increasing average value of 12% in patients’ functional activity within 3 treatments and 24% within 6 treatments.
