This study was designed to compare effects of open-chain and close-chain kinetics on proprioception, muscles’ strength and functionality on individual with knee osteoarthritis. Eight-week experimental study was conducted on twenty-five participants. Participants were randomized into two groups. The first group was involved in close-chain exercises (kinesthesia and balance exercises). The second group was involved in open-chain exercises in form strengthening exercises. Their knee proprioception, functional performances, severity of osteoarthritis, muscles’ strength and pain were assessed pre-exercise and post-exercise intervention. Twenty-five participants completed this study giving 16.67% attrition rate. Their mean age was 62.7 ± 8.5 years. The close-chain group showed significantly better improvement than the open-chain group in physical function, energy, role limitation, pain and severity of osteoarthritis. The close-chain group performed significantly better in all performances and proprioception after interventions. It was concluded that close-chain kinematics is more effective in improving proprioception functional performances in individuals with knee osteoarthritis.
