Effectiveness of close kinetic chain exercise versus open kinetic chain exercise in patients with knee joint osteoarthritis: a comparative study

Abstract

Purpose: The purpose of the study was to find out the effectiveness of close kinetic chain exercise versus open kinetic chain exercise in patients with knee joint osteoarthritis. Objectives: To find out the effectiveness of close kinetic chain exercise versus open kinetic in patients with knee joint osteoarthritis. Methodology: An experimental study design was selected to carry out the research. The experimental study had conduct to find out the objectives. Results: In this research, 20 participants were included in this study. 10 in the close kinetic chain exercise along with conventional physiotherapy group (experimental group) and 10 in the open kinetic chain exercise along with conventional physiotherapy (control group). Each participant of both experimental and control group scored on Numeric Pain Rating Scale (NPRS) and WOMAC before and after completion of treatment. Mann Whitney U test applied to the post-test pain score of the participants in the experimental group and control group were revealed a statistically significant difference at the level of (P= 0.001, U= 14.00). Disability reduction of the Numerical Pain Rating Scale (NPRS) in the experimental group was statistically significantly higher than the control group (U= 14.00, P = 0.005). Following application of treatment the study found that the experimental group showed a significant improvement (p<0.05) in case of knee osteoarthritis. In this research, close kinetic chain exercise along with conventional physiotherapy was more effective than open kinetic chain exercise along with conventional physiotherapy. Conclusion: The result of this experimental study has identified the effectiveness of Close Kinetic Chain exercise along with conventional physiotherapy is better treatment than Open Kinetic Chain exercise along with conventional physiotherapy alone for reducing pain and disability in osteoarthritis patient.
